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
Amy Y. Conry Davis states, “Deforestation and human population growth is responsible for sloth habitat loss.” Plus, in the exact same article it declares, “They depend on trees as the main staples of their diet as well as shelter.” The first cite evidence is saying how deforestation and human overpopulation growth is using up a bunch of resources that sloths need to survive off of, and if there is too many people it leads to more wood that needs to be used, and using to much wood will desamate the trees and the organisms inside them. The second cited evidence is giving the same explanation as the first cited evidence states, but is mostly lenient on deforestation, sloths, and how they need trees in their daily life for basic necessities. All of that combined together explains how deforestation and humans overpopulating puts a grave threat to sloths and
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.
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.
2a. If sunlight were to disappear almost completely, it would leave lasting effects on many organisms such as an earthworm, a shark, a maple tree, a saguaro cactus, or a teenager. While looking at an earth worm, the short term effects would be beginning to see more of the species during the day. Earthworms are nocturnal, so they live beneath the surface when it is daylight and come out once the sun goes down. Because of this in the long run, the earthworm species would eventually become overpopulated; they would be above the surface more, so they would have more time to reproduce.
The Hawaiian monk seal, or Monachus schauinslandi, was one of the original species to be placed under the Endangered Species Act that was enacted in 1973. As of 2010, the population of the monk seal is approximately 1,100, with an annual decrease of approximately 4.5%. The Hawaiian monk seal is primarily found on the Northwestern Hawaiian Islands that are made up of coral reef atolls, seamounts, banks, and shoals. This is due to the fact that the monk seals primarily forage on the barrier reefs of the atolls, on submerged reefs, and on banks further from the atolls (Curtice et al, 2011). The monk seals primarily like to look for food on the surface of the ocean floor and will search for food in depths up to 500 meters.

“ 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.
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”
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].
