Question

a desert biome receives very little rainfall. which adaptation in plants is most likely a response to this physical factor? little amounts of chlorophyll to conserve energy during the hottest season. shallow roots that absorb water quickly after rainfall. broad, flat leaves to capture less sunlight. large, brightly colored flowers attract pollinators year - round.

Explanation:

In a desert with little rainfall, plants need to efficiently obtain water when it is available. Shallow roots can quickly absorb water from the surface - layer soil after rainfall. Little chlorophyll would limit photosynthesis and is not a typical water - related adaptation. Broad, flat leaves increase water loss through transpiration. Large, brightly colored flowers are more related to reproduction and not to water - conservation in a dry environment.

Answer:

Shallow roots that absorb water quickly after rainfall.
