why are desert soils low in organic matter?

a. the temperatures are too high.

b. there are too many grazing animals.

c. there are not enough plants.

d. there are not enough minerals.

A. The temperatures are too high.

Explanation:

A desert is a region with extremes of temperatures and little to no rainfall.

Organic matter are the remains of organisms that have died. They are a very important component of soils.

Where temperatures are very extreme, there would be little to no life. Only special organisms that have evolved to adapt will survive such region.

Due to the low amount of plant and animal lives owing from the high temperature of deserts, little to no organic matter forms.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

the answer would be knowledge about cars!
