Answer: d. Why do biomes with low rainfall have low biodiversity?
Explanation:
A biome can be defined as naturally occurring community of fauna and flora in a particular region, example forest.
The environment has a major role over the development of biome. The abiotic environmental factors like water, air, soil and others can exert an influence over the biome.
The biomes with low rainfall will influence the growth of plants or floral species in a biome. The biome will experience low plant growth in absence of adequate rainfall the living plant species will die in scarcity of water. Here, rainfall is the environmental pressure.
Based on the above description, option. d is the correct question that a teacher should ask to teach the influence of environmental pressure of a biome.
