The Amur leopard is a critically endangered animal that is currently population the temperate forests in The Far East of Russia and the Northeast Chinese Convinces. Sadly the Amur Leopard faces harsh winters with extreme cold and crucially hot summers. Studies have shown that there is an estimated amount of 60 Amur leopards left of its species in the world. The ecosystem for the Amur Leopard inhabits many abiotic and biotic factors. Amur Leopards prey is all Biotic. Such as Roe Deer, Sika Deers, small Wild Boars, Hares, Badgers, and Raccoon Dogs. other things such as trees and plants are also biotic factors in the area of the Amur Leopard. Abiotic factors in the ecosystem make up of soil, water, and rocks. A symbiotic relationship that The food web that the Amur Leopard’s food chain has 3 concepts, Commensalism, Mutualism, Parasitism. Parasitism is when the Amur Leopard eats a carcass that has worms, the worms then feed off of the leopard. An example of Mutualism s, when the Leopard is done eating, it leaves the carcass and the scavengers come and finish it off, this is mutualism because both the Leopard and the scavengers get fed. An example of Commensalism is when the Leopard sleeps in a tree the leopard benefits and the tree is not affected. The Amur Leopard has to deal with many limiting factors in order to survive on a daily basis. One of the most common and obvious is overhunting of prey and poaching. The Amur leopard is the top predator in its landscape. They're a crucial role for keeping the right balance of species in their area. It also affects the health of the forests and wider environment, which provides local wildlife and people with food, water, and other resources. The Amur Leopard is the apex predator of its environment. Which means that the Amur Leopard has no natural predator, although very vulnerable to humans. Playing the role as the top predator is very important because the top predator has the responsibility to make sure that all animals and animal populations are in check. If the Amur Leopard becomes extinct, there will be many negative impacts on the ecosystem. Without the Amur Leopard, the animals they prey on may have less control over their potential population growth and may overgraze their proffered plant choices, which will affect that ecosystem's biodiversity. Also, without the Amur Leopard there to even out the populations, there will be too many tertiary consumers so the secondary consumers will become less, which is not good for the food chain, nor the biodiversity in the Amur Leopard's habitat. If the Amur Leopard disappears from the food chain, because those animals of the animals that are no longer preyed on by the Amur Leopard will overgraze their proffered plant choice, this is the main effect the Amur Leopard's extinction will have on the environment. The trophic level that the Amur leopard is placed on is level 4. According to the "Rule of Ten", only 10% of the energy is transferred from one organism to another.
