a the interactions between different species and abiotic factors in an ecological community.
b the diverse range of ecosystems occupied by species within the biosphere.
c the total number of different species present in a particular ecosystem.
d the variety of genes present in a population of organisms.

Explanation:

• Option A: Describes ecosystem - level interactions (biotic - abiotic), not species diversity.
• Option B: Refers to ecosystem diversity (range of ecosystems), not species diversity.
• Option C: Species diversity is about the number of different species in an ecosystem. This option correctly focuses on species within an ecosystem.
• Option D: Describes genetic diversity (variety of genes in a population), not species diversity.

Answer:

C. The total number of different species present in a particular ecosystem.
