Amur Tiger

Biome

Right now, the Amur tiger can only be found in the Sikhote-Alin range in the Primorski and Khabarovsk provinces of the Russian Far East, small pockets around the border of China, and possibly in North Korea. Therefore, they are mostly found in the Russian arctic tundra.

Role in the Food Chain

Due to the fact that Amur Tigers don't have any predators, their main role in the food chain is keeping the wild boar and deer population from over populating, which extremely helps the agriculture.

Why They Are Endangered

They are endangered due to illegal wildlife trade. Also, the increase of Russian logging has lead to the loss of their habitat. Right now it is estimated that there are 540 left. In the 1940s they were pushed to the edge of extinction but since Russia made the killing of these animals illegal, the population has grown.

What Happens if They Become Extinct

The increase in the Amur Tiger’s prey (deer and wild boar) would take a pivotal toll on the agriculture of the land. The harvest of the forest would struggle to survive.


Texas Wild Rice

Biome

Grows only in the freshwater of the San Marcos river. Texas Wild Rice is an aquatic plant that grows in the water with only its stem tips rising above the surface.

Why They Are Endangered

The loss and degrading of their natural habitat of or around the San Marcos river due to pollution and industrialization. The grass occurs in a relatively narrow range of water conditions, including temperature, pH, and turbidity, flow rates, and substrate types.


What Happens if They Become Extinct

It is known to provide habitat for the fountain darter, an endangered species of fish, as well as several other organisms; however, the full extent of its ecological role remains unclear. It will be nursed along by humans for the foreseeable future, but it may never regain its full glory.


Role in the Food Chain

The extinction of the Texas Wild Rice would soon lead to the extinction of the Fountain Darter, which would take a devastating toll on the predators of the Fountain Darter.
