Questions: Chapter 11 Multiple Choice Question 3 Part A The greatest species diversity is found in which of the following groups? insects birds mammals flowering plants fish

The answer is the first one: insects.

Explanation for each option:

• Insects: Insects are the most diverse group of organisms on Earth, with over a million described species and potentially millions more undiscovered. They represent the largest portion of biodiversity in terms of species count.

• Birds: While birds are diverse, with around 10,000 known species, they do not come close to the diversity seen in insects.

• Mammals: Mammals have approximately 6,400 species, which is significantly less than the diversity found in insects.

• Flowering plants: Flowering plants, or angiosperms, are highly diverse, with an estimated 300,000 species. However, this number is still less than the diversity found in insects.

• Fish: Fish are diverse, with around 34,000 species, but again, this is far fewer than the number of insect species.

Summary: Insects have the greatest species diversity among the groups listed, making them the most diverse group of organisms on the planet.
