which of the following statements about levels of biodiversity is correct?

The correct statement about levels of biodiversity is the one that says biodiversity is described at three main levels: genetic diversity, species diversity, and ecosystem diversity.

The three levels in simple terms

• Genetic diversity – variation in genes within a species (for example, different varieties of rice or dogs).

• Species diversity – variety and number of different species in a given area (e.g., a rainforest with hundreds of tree and animal species).

• Ecosystem diversity – variety of ecosystems or habitats in a region (forests, grasslands, wetlands, deserts, coral reefs, etc.).

So if your options look something like:

• genetic, species, biome
• molecular, species, biome
• genetic, population, ecosystem
• genetic, species, ecosystem

…the correct option is:

genetic, species, ecosystem.
