The different types of components of an ecosystem are connected. it is very important to know, because a change in the amount of abiotic resources available or a change in the size of anyone in a certain population of organisms can have impact on the size of the other populations found in that ecosystem. Also the interactions that take place between the organisms that are found in an ecosystem can change the characteristics of some populations. One example that characteristics can be influenced by population interactions include the proportion of individuals within a population to have a specific traits or the average height or weight of the members of that population. One type of interaction that can result in a change in the characteristics of a population is a predation. It often has strong influence on the characteristics of a prey population. biologist study how the characteristics of a specific prey population change in the response to a specific type of predation and to understand how different types of interactions can result in a change in the characteristics of a population. The two types of predations is hunting or sit and wait. My task was to answer the guiding question of why will the characteristics of a bug population change in a different way in the response of the different predations. While i was playing with the bug simulations …show more content…
. I decided to conduct my investigation in this way because the graphs backed up my evidence and it help me out with my argument because everything that I was arguing was proved right by the
To conduct the experiment, the beetles were massed, then attached to a petri dish with a 30 centimeter piece of dental floss. The beetle’s mass was the independent variable. Afterwards, the floss was tied to the beetle’s midsection with a slip knot. Then, the beetle was placed on a piece of fabric with the petri dish attached to it. As soon as the beetle was able to move with one paperclip inside the petri dish, more were added, one by one, until it could not move any further. After the beetle could not pull any more, the paperclips were massed and the results were recorded. The dependent variable was the mass that the beetles could pull. No control group was included in this experiment.
The next topic for discussion in this paper is ecology. This will include, preferred habitats and interactions with abiotic and biotic elements of the environment.
In conclusion the experiment was carried out and had great success proving my prediction to be correct and enabling solid and valid results which were able to be put in a graph. I believe my prediction could have been more accurate or more backed up if I had made a quantitative prediction. Though what I believed would happen did happen during the experiment which helped to understand the graph and the results which led me to be able to write a thorough report on them.
The humorous essay City Critters makes it clear that humans with their creation of vast amounts of waste have a great deal of responsibility for the pest problem in cities by. In this essay I will discuss how humans could be pest to.
The processes of predation affect virtually every species to some degree or another. Predation can be defined as when members of one species eat (and/or kill) those of another species. The specific type of predation between wolves and large ungulates involves carnivores preying on herbivores. Predation can have many possible effects on the interrelations of populations. To draw any correlations between the effects of these predator-prey interactions requires studies of a long duration, and statistical analysis of large data sets representative of the populations as a whole.
a.) Choosing organisms from four different trophic levels of this four web as examples, explain how energy is obtained at each trophic level. Since energy is a necessary part of how an organism survives, how it obtains it’s energy is crucial. When you look at an ecosystem, and all the organisms living within that ecosystem, you can link many of the species together by their dependence on each other. Scientists will look at these links to see how they depend on each other, or in other words, where their main source of energy and nutrition is.
This experiment that was executed was about breeding fruit flies (Drosophila). The purpose of this experiment was to further understand autosomal and sex linked traits. The reason that fruit flies were used was due to the minimal cost, the minimal space they take up, their simple living requirements, and their short lifespan. We crossed females with wings and sepia eyes, which was a mutation, and apterous males with red eyes. The absence of wings is also a mutation.
The objective of this experiment is to determine what genes are responsible for the white-eye color in two strains of Drosophila melanogaster, known as the common fruit fly. Drosophila is used as the experimental organism for many reasons which include its small size, easy maintenance, short 10 day generation time, and a fully sequenced genome. The characteristics of the wild type, which is the most common phenotype found in nature, include brick red eyes, long wings, gray/tan body, and smooth bristles. Of course, there are mutations that occur that cause specific traits to deviate from the wild-type phenotype. These traits include wing length, bristle shape, body color, and eye color.

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
As environments and conditions change, the organisms living there must also change. Developing defensive mechanisms such as mimicry, camouflage, and chemical combat increases the chance for survival. Adaptation is necessary for organisms to survive predation.

Seventh, in some groups of insects, truly social behavior has evolved. Social behavior will allow a large population to survive through difficult periods via cooperation in food gathering, food storage, temperature control, and colony
Arthropods are in the kingdom Animalia which is in the subphylum Arthropoda. A species can be classified as an Arthropod if they have an exoskeleton, a coelom, and if they are mostly dioecious. An “ exoskeleton is an external skeleton made of chitin. [A] coelom is fluid filled cavity between organs and body wall” (Babin,2017). Examples of Arthropods are: spiders, ticks, millipedes, and centipedes. The objective of this experiment was to find Arthropods and test. Different habitats were established to see which will produce a greater amount of Arthropod. It was believed that the Arthropod diversity of a shaded area will be more that that of an area near a canal. The shaded area would have more arthropod diversity because more plants would be around it. Since there will be leaves and trees, plant diversity will be greater. Also, having “ plant diversity can positively affect arthropod{s}” ( Bennett and Gratton, 2013) because there will be more arthropods to utilize.
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.
