Imagine if all the mammals disappeared then then animals would go extinct and will humans be next? Burmese pythons have both positive and negative effects on the Florida everglades ecosystem. Burmese Pythons eat common animals in this ecosystem. This ecosystem common animals percentages are decreasing and also their population too. Finally, Burmese Pythons affect future animals and the natural food chain.
of food per day for some large male otters. Their diet being mainly sea urchins, the sea otters keep the urchin population under control which allows for other life within the kelp ecosystem to survive and create a balanced ecosystem. Without the sea otters in a kelp ecosystem, the sea urchins can take over and disrupt the ecosystem by killing out some algae species and some fish which live in the
In the article, “Rescue in the Rainforest” Mackenzie Carro states, “As a result, all sorts of organisms make their homes on sloths' bodies. One type of algae lives nowhere on the planet except on sloth fur. A kind of moth also makes its home on the sloth. When the moths die, their bodies decompose in the sloth’s fur, providing a meal for the algae.” This text is explaining how the sloths are home to many creatures, and how they can easily die if the sloth population drops down to zero.
In both of these articles by Christine Dell’Amore and Matt Miller, they discuss how these top predators impact the island, why they are they important, and should humans interfere? On the island of Isle Royale, there is a variety of animals that mostly just consume vegetation; therefore, they need wolves to balance out the food chain. But, the island is only accessible during the winter when stable ice bridges are created. Unfortunately, the ice bridges have not been forming due to warmer winters. Leaving a small count of wolves on the island with no new genes to mix in.
Sadly, many Americans believe that losing the wolves would not be a bad thing for the prey’s sake, but in all reality losing the wolves would be devastating. One major thing that is present in all ecosystems, the place in which animals live, is a trophic cascade. A trophic cascade is explained in the essay as a “sequence of impacts down the food chain” (578). Hannibal gives the reader this example: “…In Wyoming’s Yellowstone National Park … wolves were virtually wiped out in the 1920’s and reintroduced in the ‘90s. Since the wolves have come back, scientists have noted an unexpected improvement in many of the park’s degraded stream areas”
Sea otters live in shallow coastal waters near the northern pacific. These marine animals live close to states like Washington, Oregon, and northern California. They spend most of their time in the water, but scavenge land for food sources like plants or small animals. Otters can also hide in kelp forest to hide from predators. They live in shallow water in the northern pacific for ultimate food sources and access to land.
Eagles, hawks, roadrunners, coyotes and foxes are predators
In a way they are correct however, the wolves started the growth of the ecosystem again. More birds began to come because the terrain regained strength causing trees to be healthy and stronger. The birds made habitats there causing hawks and other prey to come due to the increase of birds. Beavers began to build dens in the rivers again which also provided a home for amphibians, otters, and other animals. The circle of life began to blossom again and it all started with the wolves contribution to the ecosystem.

“ The non native tortoises are eating the fruit produced by the ebony trees and dispersing their seed all over the island. Over a decade after the Aldabra tortoises were introduced researchers are nothing that the endangered ebony forests are beginning to recover” (J. Francis Wolfe). This shows and proves that the invasive species Aldabra tortoises are helping grow back the ebony trees. Also in the text it states, “ Not only do the tortoises facilitate the spreading of the seed, they are also aiding in the germination process due to the seeds passing through their digestive systems.” Thus explains that the tortoises don't just help on way, they help out in many ways.
Animals in the order Carnivora only eat meat and feed on other animals. The sea otters are part of this order. The order Carnivora consists of twelve families, nine of which live on the land. The family of this mammal is called the mustelidae. Being meat eaters, carnivores are on top of the food chain and they form the highest trophic levels within ecosystems.
Past and present occurrences involving gray wolves have led us to perceive them as having a negative impact on the environment. Gray wolves have a negative impact on the environment because of their vicious attacks and attempted attacks. Although this certain type of wolf is very resourceful and well researched, they use it to their advantage to fight off their prey. Unfortunately, their prey is not always another animal, but a human being. Their violent behavior is what makes them a negative impact on the environment.
1911, Southern sea otters swam on every coast near the Pacific, Including the Sea of Japan. They lived in large kelp forests near shores and would usually stay on the surface of the water only diving when food was necessary. Being the most important part of the food chain, sea otters kept anything that would eat the seaweed like snails, and sea urchin populations in check so the kelp forests wouldn 't die out. Southern sea otter populations near the west were unknown, but the American east coast has around “15,000 otters through 1911 to 1928 and growth kept going”(The Monterey Bay Aquarium).
Sea mammals are an important species in general, so Alaskans like to keep them protected. An office named “Marine Mammals Management” was created to keep these species safe (Fishing in Alaska). One of the most important sea mammals would be the sea otter. These little creatures play a huge ecological role for the environment. Big game animals can be from a dozen of a different animals.
Hence, deforestation increases. This is another effect of overpopulation that impacts the worsening of the environment [2]. For example decreased forest size increases the amount of carbon in the environment. More specifically, deforestation affects the wildlife and results in biodiversity loss and species extinction [1].
