Topic 2.1: Introduction to Biodiversity
Learning Objective: ERT-2.A
Explain levels of biodiversity and their importance to ecosystems.
Essential Knowledge: ERT-2.A.1
Biodiversity in an ecosystem includes genetic, species, and habitat diversity.
Essential Knowledge: ERT-2.A.2
The more genetically diverse a population is, the better it can respond to environmental stressors. Additionally, a population bottleneck can lead to a loss of genetic diversity.
Essential Knowledge: ERT-2.A.3
Ecosystems that have a larger number of species are more likely to recover from disruptions.
Essential Knowledge: ERT-2.A.4
Loss of habitat leads to a loss of specialist species, followed by a loss of generalist species. It also leads to reduced numbers of species that have large territorial requirements.
Essential Knowledge: ERT-2.A.5
Species richness refers to the number of different species found in an ecosystem.
