Answer 2

Tundra is a biome characterised by temperature below -25° Fahrenheit and permafrost ( frozen soil sub layer ) . It is of two types, alpine and arctic. Tundra animals are adapted to living in very cold temperatures. They also have the ability to raise offspring during very short summer time. Some of them migrate to warmer areas during harsh winters while others hibernate.

Many types of mammals, fish, birds and insects are found in tundra biome. Reptiles and amphibians are absent due to extreme cold climate. These animals interact with each other in many ways. They compete with each other for resources and also hunt each other for food. Competition is more harsh since resources are very limited here.

A typical example of such animal interactions is the food web present here. Plant species ( producers ) are consumed by herbivores like musk, oxen pikas etc. These herbivores are hunted by secondary consumers like brown bears and arctic foxes.
