Answer: (D)

Verified step by step guidance

1. Understand the concept of species diversity: Species diversity refers to the variety of different species within a given ecosystem or area. It is one of the components of biodiversity, alongside genetic diversity and ecosystem diversity.
2. Analyze the options provided: Each option represents a different aspect of biodiversity. For example, genetic variation within a population refers to genetic diversity, while the number of ecosystems in a region refers to ecosystem diversity.
3. Focus on the correct definition: Species diversity specifically involves the presence of multiple species coexisting in the same area, contributing to the overall variety of life forms.
4. Evaluate the correct answer: A forest containing oak, pine, and maple trees represents species diversity because it includes multiple species of trees within the same ecosystem.
5. Conclude: The other options do not represent species diversity because they either focus on genetic diversity (variation within a population) or ecosystem diversity (number of ecosystems in a region).
