Describe animal interactions that affect populations in the tundra ecosystem.

Interferes with each other number/count and hence affects the activities physical or chemical associated with it .

Explanation:

There are several varieties of animals in the tundra region in which some are extremely dangerous animals such as polar bear which feed on both flesh and plants such as seals, fish, birds, caribou, musk oxen, berries, and leaves. They are extremely powerful with huge diet. The species on which it feed has a slow growth rate as compared to the rate at which they are fed upon. Thus, the population of these lower level animals is in danger. Along with it several animals hibernate for a long period due to extreme cold and hence the population of species on which they feed upon grow tremendously

Also some species of animals feed on microorganism that are the only source of disintegrating dead bodies of animals and plants. Excessive feeding on such microorganism may lead to problem of improper or incomplete or slow dead organic matter disintegration
