Question

which statement about biomes is true?
a. different biomes share similar plants and wildlife.
b. each biome has only one ecosystem.
c. there are only three biomes on the earth.
d. biomes are determined by climate zones.

Explanation:

• Option A: Different biomes have distinct plant and animal communities, not similar ones. So A is incorrect.
• Option B: A biome can contain multiple ecosystems. For example, a forest biome has many different forest ecosystems. So B is incorrect.
• Option C: There are more than three biomes on Earth (e.g., tundra, desert, forest, grassland, aquatic, etc.). So C is incorrect.
• Option D: Biomes are largely determined by climate zones (temperature, precipitation patterns), which influence the types of plants and animals that can thrive there. So D is correct.

Answer:

D. Biomes are determined by climate zones.
