Question

3 what is biodiversity? a the number of protected areas in a country b the variety of different ecosystems on earth c the variety of life, including species, genes, and ecosystems d the amount of rainfall in an ecosystem

Explanation:

• Option A: Protected areas' number is not biodiversity. Biodiversity is about life's variety, not protected areas count.
• Option B: Biodiversity includes more than just ecosystems (also species, genes), so this is incomplete.
• Option C: Biodiversity is defined as the variety of life at all levels - species (different organisms), genes (genetic variation within species), and ecosystems (different habitats/ecosystems), so this matches the definition.
• Option D: Rainfall amount is a climate/ecosystem factor, not biodiversity.

Answer:

C. The variety of life, including species, genes, and ecosystems
