adaptibility of animals?????

[param]

What are the problems faced by animals that live in dry soil?

Diffrentiate the adaptibility of insects and mamals to live on land???????

any help will be appreciated.........

At the soil part, do you mean like worms? Because usually animals don't have much business with the soil
Whell, adaptability is usually reduced to finding food. Mamals are a lot bigger than insects so they require more food. In tough regions where food is scarce insects can live and mamals can't

or do you mean in deserts and such- where it would be the lack of water mainly, and lack of food (thats why you get so many more insects in the wild because they dont need that much)- But mammals also face the problems of heat and humidity.(i.e storing water)
