Question

5 deserts are fascinating ecosystems. Because they have so little water, any animal or plant that lives in a desert must be suited for the climate. The kangaroo rat does not drink any water. It gets moisture from seeds. Cacti and other desert plants have root systems that spread out over a large area just below the ground's surface. These roots quickly collect any rain that falls then they store it in stems that can expand to hold a considerable amount of moisture. The spines on the cacti keep desert animals from getting to the water.

The paragraph tells mainly
(A) how the kangaroo rat gets moisture.
(B) how animals and plants survive in the desert.
(C) about the widespread root systems of desert plants.
(D) about why the desert has so little water.​

Answer 1

B

Step-by-step explanation:

The answer can't be A because the passage also gives a lot of information about how cacti and plants get water. It can't be C because the passage also focuses on how kangaroo rats get water. It also can't be D because the passage never explains WHY the desert has little water, just that it does.

The answer is B because the passage explains how animals (kangaroo rats) and plants (cacti) survive in the dry desert.
