Question

In desert grasslands, which type of animals are relatively more abundant
A. Diurnal
B. Arboreal
C. Aquatic
D. Fossorial

Answer 1

Hint: These are the types of animals which generally dig the soil to live underground. The mode of existence is generally subterranean type. These habitats are ideal for grazing and digging or for fossil animals such as sheep, rabbits, mice, owls, rats, etc. These animals live underground in burrows (at low temperature)

Complete answer:
Grazing animals abound in desert grasslands which are adapted to live underground in burrows (at low temperatures). Desert animals prefer to live below the surface of the earth. These animals are called fossorials.

Additional information: Animals that reside permanently or for most of their lives in burrows or below the surface of the earth are called burrowing animals or fossils and their mode of existence is described as subterranean or subterranean. In the desert grasslands, what types of Fossorial animals are relatively more abundant. In desert grasslands, temperatures are relatively high, so animals have to adapt to the temperature.
Most of the fossil animals that live in these areas are adapted to live underground where the temperature is relatively low inside the burrows.
So, the correct answer is ‘Fossorial’.

Note: In deserts, animals prefer to live below the surface of the earth. These animals are called fossorial. Animals that reside permanently or for most of their lives in burrows or below the surface of the earth are called burrowing or ditched animals and their mode of existence is described as underground or underground. In the desert biome, vegetation is sparse and the soil sandy. In desert grasslands, there is a hot summer, a cold winter, and seasonal rains (25-75 cm). Precipitation does not form forests and exceeds the amount that induces desert formation.
