Recommended: Human impact on ecosystem
Predators, prey, and scavengers that are native to the same area will not harm the population of each other’s species nor harm the environment if unprovoked. The food chain, if undisrupted, is a complex system of animals that remained perfectly stable before humans intervened and began to damage ecosystems and the population of animals that live in a specific ecosystem. As humans began to intervene, species began to die off at a more rapid pace that affected all ecosystems around the world. Many animal relationships that were doing perfectly fine for long periods of time ended up being disrupted by extinction or being forced out of a certain area. When one species is harmed or killed off, it hurts every species in the food chain because animals lose a predator and the population becomes uncontrolled, predators lose a type of prey and they can no longer support themselves, and scavengers lose a food source because of the fact that they no longer have the ability to eat that type of animal. Predators, prey, and scavengers are all necessary …show more content…
There must be more prey than predators due to the fact that many types of predator may eat one type of prey. Scavengers also eat the unfinished remains of other animals killed by predators before decomposers had the chance to start decompose the carcass of the animal. By eating the remains of animals that had previously been killed, it prevents overhunting and species extinction. Scavengers are also viewed as prey to many predators due to their presumable inability to fight back when attacked by a larger and more skilled predator. Scavengers are crucial to the ecosystem because they provide food for predators and clean up after predators. All parts of an ecosystem, assuming they are indigenous to the area are necessary because they all help each
Figure 2 shows that the Panda is yet again a Primary Consumer or the Food Chain. Like the other Figures (diagrams), the tiger is the main apex predator of the food chain. In addition, the maggots are also included because they are scavengers who break down dead plants and animals. An arrow from the Decomposer attached with the Producer show that the plants would get essential nutrients from the maggots, otherwise dead matter and waste would pile up.
For example the canopies of kelp provide shelter for many organisms . Because the kelp is able to float, it creates a canopy. This canopy has warm temperatures and slow water currents, providing a home to defenseless young. This is important because the kelp is able to protect many organisms from predators and rough storms (6). Kelp is also the base of the food chain. Since kelp is the base of the food chain many organisms eat kelp and other animals eat them.This is important because without the kelp all the primary consumers would starve having no other food source (5). Finally each part of kelp is home to a different species. Because each part of kelp is home to a different species, many species breed in them. This is important because if the kelp where gone there would be no place for the organisms to breed downsizing their population (4). Overall kelp is providing food and shelter to many
1) Inspiration: Grey wolves are considered as apex predators, meaning that they are at the top of the food chain. Grey
The California condor or, Gymnogyps californianus, for instance, it has a hooked beak so that they can dig into the carcasses left by previous predators. Unlike its close looking cousins like the eagle or vultures, the condors don’t have a good sense of smell so they depend on their eyes to see their prey. They consume mostly large mammals on which they can eat for days. The California condor is often called "nature’s cleanup crew", because they eat all the dead carcasses left behind. Being scavengers, Condors don’t kill their food; instead they depend on other predators in the area to kill the animals so they can consume the remains.
Predators called prudent predators select prey of the highest quality and will switch prey when other foods become more profitable. Prudent predators show preference for the prey they consume, in order to maximise net energy gain per unit time. An important factor in predation-prey interactions is the rate at which individual predators can capture individual prey items. The response of the predator consumption rate to increases in prey density is called the functional response
Predation could limit the prey distribution and decrease abundance. Such limitation may be desirable in the case of pest species, or undesirable to some individuals as with game animals or endangered species. Predation may also act as a major selective force. The effects of predator prey coevolution can explain many evolutionary adaptations in both predator and prey species. The effects of wolf predation on species of large ungulates have proven to be controversial and elusive.
Native plants in any given area have adapted to all the other organisms in a given area and genetically diverse ecosystems are generally maintained.
...rganisms’ populations to decrease as well. On the other hand, if the predator’s population was to decrease drastically, then the prey’s population would come to a rise. There may then not be enough food available for the prey. This could also cause populations to decrease.
...and especially to the ecosystem with the killing of those animals and primarily the poisons that they use can totally destroy an ecosystem and do much more harm than good.
People today use hunting as a sport. Of course, not everyone agrees with hunting, but those who like to hunt justify their actions by saying that they are helping with the overpopulation of animals, like deer. The truth is that we are affecting the population of animals. Animal overpopulation can be due to the loss of an animal’s natural predator. Predators are extremely important in an ecosystem, and they are nature’s way of controlling the animal population. In William Stolzenburg’s book, Where the Wild Things Were: Life, Death, and Ecological Wreckage in a Land of Vanishing Predators, he addresses the importance of predators in an ecosystem. He discusses an experiment done by a zoologist named Robert T. Paine. Paine decided to do an experiment to see what happens when one disrupts an ecosystem. He conducted his experiment on rocks along the shore in which a species of starfish was the top predator. Paine’s experiment consisted of grabbing the starfish off the rocks and throwing them into the ocean. His results showed that one single species has a tremendous effect on its ecosystem. After getting rid of the top predator, about half of the species that
Humans are destructive. Not a lot of us think about how what we do affects the world around us. We almost act like we are the only ones on this planet. We go around polluting and destroying our world with no regard for our actions. The things that live out in the wild are paying the price for it. Every day that passes there is another animal or plant that is placed on an endangered list. This is happening at an alarming rate. Because of man’s desire to expand and conquer their surroundings, there are animals and plants that are on the brink of extinction that will not be around for our kids and future generations to enjoy if something is not done about it now. This problem has been going on for hundreds of years. There are animals and plants that can only been seen in paintings or early photography. It is because of our early ancestors that we have this problem today and we have to do more to prevent more animals and plants from disappearing forever.
7- MEETING THE AVENGERS 2225 When Asgardians decided to go all out, they went all out. He and Loki were surrounded by a dozen guards, who had apparently pulled out their Sunday best. And then dipped it in solid gold. Joining their little parade was some old geezer in elaborately layered robes. The chain of office draped over each of his shoulders was made up of numerous linked plates, surprisingly of engraved black metal rather than Asgard’s ever present gold.
Biodiversity loss can lead to extinction, and hurt human life. It is our responsibility to take care of the environment. We bring in machines that harm the environment and destroy animal life. We need to limit ourselves on how much land and resources we consume. There are major issues that are causing species to become extinct and hurt our way of life and other animals do to the change in food chain.
Everyone’s all seen those wildlife shows on tv. The shows on National Geographic and such, showing animals in beautiful environments, everything lush and growing and nothing at all wrong that could threaten these creatures and places. But, have anyone seen the other side? The side where all these beautiful creatures and plants starve, are decimated by predators that have never been there before, and sometime even become poisoned by their very own homes and habitats? Of course no one has. That doesn’t mean that its not happening. It is happening, and its happening everywhere. And guess who is to blame? People. Society. Humans as a race pollute the environment, hunt animals simply for their parts, fish way more than humans will ever need just for the sake of money, introduce new species to new places for our own gain, and even purposefully destroy entire regions just for human expansion. And its starting to take its toll. While it is true that nature is constantly in flux and certain species come and go, humans are causing more species to disappear in the past few hundred years then nature has ever caused since the age of the dinosaurs, and therefore it is up to humans to repair the damage caused, be it cleaning the environment and habitats of these creatures, or taking more direct action to protect and preserve the species that are on the brink of extinction.
Stray animals are dangerous reason being is children or elderly people can be bit while walking or playing around at parks. I live in Mercedes and at one point when I was walking from stars to the high school, and stray dog for no reason started growing at me and my instinct was to run until I got the a building. This can happen to anyone, they can be attacked trying to touch a stray or just simply walking by, or even worse a child can catch a disease. Also owners with their pets are also getting attacked by stray animals because they strays tend to be over protective of their territory, or they just want to fight with the pet of the owner.
