AP Environmental Science Unit (# 2) Student Notes 2.1 ENDURING UNDERSTANDING: Ecosystems have structure and diversity that change over time. LEARNING OBJECTIVE ERT-2.A Explain levels of biodiversity and their importance to ecosystems. ESSENTIAL KNOWLEDGE: Biodiversity in an ecosystem includes genetic, species, and habitat diversity. Biodiversity – variety of different species Species – set of individuals who can mate and produce fertile offspring o 8 million to 100 million species o About 2 million identified o Unidentified species are mostly in rain forests and oceans o Species Diversity : o Number of different species and their relative abundances in a given area.
