The amphibian population has been decreasing for over twenty years now. Amphibians are the most extinct species at around sixty six percent of all the species being endangered. The leading problems for this include “habitat loss, disease, invasive species, overexploitation, and chemical pollution (Olson).” As the air and water temperature increases, the more frogs get affected by global warming causing frogs to mate latter affecting the survival rate of their babies.
Warmer temperatures are also causing ponds and lakes to become shallow, which affects frogs eggs and also affecting frogs survival rates. Humans play a big role in frogs decrease and one of the main reasons is by altering their habitats. Altering habitats removes the homes of many

Another big amphibian killer is pesticides. Pesticides have shown to decrease the amphibian population greatley. A study was conducted and has shown to kill one hundred percent of all frogs that got exposed to common pesticides used to spray plants with. Pollution can also affect amphibians, but mainly maile frogs. Male frogs have been tested and have shown to have undeveloped sperm in the testes after exposed to pollution. Undeveloped sperm would lead to not being able to reproduce which would lead to a big decrease of frogs in the area. Out of two hundred and thirty three male frogs tested, about thirteen percent of them have undeveloped sperm.
Effects on other organisms/ecosystems/humans Frogs are needed in the ecosystem for five main reasons, the first on being to play their role in the food chain. Frogs “provide a very efficient transfer of solar energy.” They eat plants for energy which allows their predators to eat them for energy. Frogs are also a good pest control option, they eat insects that may carry diseases and help us get rid of

You can educate yourself to know what not to do to help increase the frogs population. For example, help decrease pollution, don't disrupt or destroy habitats, and don't go hunting for frogs. Watch what you throw away, and make sure you dispose of it properly. The public is also asked not to flush medicine down the toilet, because it could end up in a stream at a frogs home. Also support going green, go help plant some trees or try to recycle. There are many different programs that people have created to try and help preserve frogs you could help or donate money to.
Conclusion
So it would make sense for us to try to preserve a species that helps us so much. They have helped us get rid of diseases that would harm the human body through insects. We also use their skin to research and learn from for our own needs to benefit our bodies. Frogs are taken to labs and used as lab rats against new medicine and drugs before it is released to the
There are some nice adaptations for the Strawberry dart frog. They can extract toxic alkaloids from variance of mites, ants, millipedes, and beetles. When they extract these poisons, they store it in compounds in glands on their skin. Lisa Lester says that when the frog feels threatened, they can release the toxins stored in their glands at the enemy. (Lisa Lester, “Strawberry Poison Frogs Feed Their Babies Poison Eggs”)
Coqui frogs are harming Hawaii's environment as they begin to reproduce faster than ever. Female coquis can deposit up to 28 eggs every eight weeks (Singer et al). The environment is not able to work efficiently when these little creatures are constantly reproducing. Coqui frogs are a serious threat to native insect population because they are consuming and removing insects from forest floor to treetops (Van Valkenburg). Insects have always been the major food source for birds and with coquis around, they have to compete and search for food. When Coqui frogs feed off of mites, ant...
The Gray Tree Frog can be found anywhere ranging from southern Ontario in Canada to the southern coast in the United States. Usually it is not found west of Texas or Manitoba, Canada. The can be found at Rice Creek Field Station. The best habitat is shallow water situated close to diverse stands of willows, oaks, and pines (Craighead, 2004, p. 2). The location of water and plenty of vegetation, which not only shades the forest but also covers the ground with broken brushwood, is what needed for the frog’s ultimate survival is.
To begin with, the first characteristic that describes Hop Frog is that he is unfortunate of being a fool. One way Hop Frog is unfortunate of being a fool is that he is bullied

Species are decreasing and becoming extinct over time due to climate warming. Animals and plants have developed and diversified from earlier forms to become more complex organisms. Not only have living organisms changed, but so has the Earth. Over time, the world itself has changed drastically, not just the climate but the way it looks as well. The ice on the arctic is melting, causing oceans to become more acidic, oceans became deserts and pollution from our everyday lives are affecting the ozone. It all adds up and changes the world negatively. When the world changes, so do the animals within it. Climate warming has been a big part of the change we see in the population of different species. The speed of climate change is excelling, which

Different Perspectives Witness riveting stories of betrayal and revenge, where characters navigate troubling paths filled with deception, leading to unexpected and thrilling outcomes. The story “The Cask of Amontillado” written by Edgar Allan Poe is an unsettling tale about two characters, Montresor, and Fortunato, who are exploring the catacombs of Montresor. Montresor tricks Fortunato into his trap, additionally he starts to close off the opening and throws his flambeau in. The movie “The Count of Monte-Cristo” produced by Kevin Reynolds is based on two characters who are friends at first; however, the antagonist Fernand betrays the protagonist Edmond Dantes. Even though Edmond, also known as The Count of Monte Cristo, finds the treasure,
Frogs are needed for everyday life. They are part of pond life. Each animal is important because even in the pond, there is a food chain. Frogs are amphibians, animals that spend half of their lives under water, and remainder on land. The first frog appeared in the early Jurassic period about 200 million years ago.

Frogs are amphibians in the order Anura. The order Anura is broken down into 22 different families of frogs and toads. Although they belong to the same order, frogs and toads are different in a lot of ways. Some of the more distinct differences are their skin and where they live. Frogs usually have smooth moist skin and toads usually have dry watery looking skin. Frogs spend most of their lives in or near water and toads spend more time on land. Amphibian means "double life." Frogs and toads each have two parts to their lives: when they live on water and when they live land. A frog's life starts in the water when it is hatched from an egg as a tadpole. A tadpole looks very different from an adult frog. A tadpole has a tail, no limbs, and breathes through gills. After a while the tadpole goes through metamorphosis. During the change the frog grows limbs, the tail disappears, it uses lungs to breathe, and it doesn't have to live in water anymore. As a tadpole, the frog feeds mostly on vegetation. The tadpoles have a small rasping mouth suited especially for scraping algea from the bottom of ponds. Depending on the species, it can take a few weeks to a year or more for the tadpoles to become fully grown. Not all frogs hatch as tadpoles. Some species of frogs hatch as froglets. Froglets look just like adult frogs but are a lot smaller. Froglets don't go through a metamophosis. Most species that hatch as froglets are found in dry places. Frogs who live in dry places where rains are seasonal have to grow up quickly because a tadpole will die if their temporary pond dries up. Adult frogs can live in water or on land, but it always needs to be near water so its respiratory organs don't dry out.
Amphibians; a declining population Around the world many animals are being affected by their changing environments, with some of the most important ones being amphibians. Currently amphibians are being killed off at an astounding rate. This decline can be contributed to many things, such as disease, habitat loss, pollution and climate change. Over the last couple decades over 40% of amphibians have officially begun to suffer population loss. This has led countless organizations to pursue a solution to this problem.
Many scientists were fascinated by the creatures that seemed to disappear from the forests of Queensland every year and during this time were thought to be hibernating. Although before they had a chance to study them in further detail the frogs became extinct.
Global warming is one of the most serious problems that people all over the world are dealing with. In fact, however, many people may not realize that global warming also affects animals as badly as it does to human. All Americans should help protect animals from global warming because global warming changes animals’ habitats, decreases food supplies of animals, and even shortens animals’ lifespan.
Global warming is a serious problem with two major effects which are increasing in sea level and degradation of wild lives. Increase in sea level is affecting the entire landmass of the earth. According to NASA, the polar ice cap is melting at the alarming rate of nine percent per decade. Arctic ice thickness has decreased 40 percent since the 1960s (Oskin). The amount of water is more than the land in our planet. If this global warming continues at this pace, soon there will be no ground left on earth. The terrestrial animals will be exterminated from the earth if glo...
