How do animals survive in the mountains?

Animals survive in the mountains by physically having thick fur and wool to protect themselves from extreme temperatures. Mountain animals also typically have hooves that help them climb the slopes of hills. Some Mountain Animals also have large lungs and a heart that help them compensate for the scarcity of oxygen at high altitudes.

What are common features of mountain animals?

The common features and characteristics of mountain animals include having thick fur as well as hard hooves. Mountain animals are also typically larger in size to not lose heat quickly as well as cool down. Animals that frequent this type of environment adapt physically to withstand and thrive within these conditions.

Which animals can you ride on a mountain?

The animals that you can ride on a mountain include donkeys and mules. They are often used to ride on a mountain by humans since they can easily be saddled and ridden in a similar manner to horses. Donkeys and mules are also gentle and steady footed.

How do forest animals adapt to the changing seasons?

Forest animals adapt to the changing seasons to be able to withstand the cold winters and hot summer temperatures. Forest animals adapt by either hibernating or migrating to warmer weather during the cold. During the warm summer seasons, forest animals typically find an abundance of food and find ways to stay cool.

How do animals help trees?

Animals help trees because they breathe oxygen and exhale carbon dioxide while plants take in carbon dioxide and emit oxygen back into their surrounding air. Plants also serve as food and shelter for animals. Plants rely on animals for seed dispersal and pollination. Plants also help with filtering water that animals drink.

How do forest fires affect animals?

Forest fires affect animals as they alter the 3 sources that animals rely on the most – food, water, and shelter. Forest fires often cause animals to move away from the areas they are used to in search of a new shelter.
