In the context of major terrestrial biomes, which ecosystem is generally considered the most biodiverse (highest species richness)?
A

C
Hot desert
D
Temperate deciduous forest
Verified step by step guidance1
Step 1: Understand the concept of biodiversity, which refers to the variety and variability of life forms within a given ecosystem, biome, or the entire Earth. Species richness is one measure of biodiversity, indicating the number of different species present.
Step 2: Review the characteristics of each biome listed: Tundra, Hot desert, Temperate deciduous forest, and Tropical rainforest. Consider factors such as climate, temperature, precipitation, and how these influence the ability of the biome to support diverse life forms.
Step 3: Recognize that tropical rainforests have warm temperatures year-round and receive high amounts of rainfall, creating ideal conditions for a wide variety of plants and animals to thrive.
Step 4: Compare this to other biomes like tundra and deserts, which have extreme conditions (cold or dry) that limit the number of species able to survive there, resulting in lower species richness.
Step 5: Conclude that among the options, the tropical rainforest is generally considered the most biodiverse terrestrial biome due to its favorable climate and complex habitat structure supporting the highest species richness.
