What your class asks

This lesson asks you to understand biodiversity as the diversity of life on Earth: the variety of organisms within a species, among the species of a community, and among communities and the habitats that support them. It also asks you to describe how variety within a species is essential for its survival. The museum holds no record that serves these expectations yet, so this lesson offers none; your class brings its own examples and sources. 1
