Topic 8.6: Biodiversity
Learning Objective: 8.6.A
Describe the relationship between ecosystem diversity and its resilience to changes in the environment.
Essential Knowledge: 8.6.A.1
Natural and artificial ecosystems with fewer component parts, and with little diversity among the parts, are often less resilient to changes in the environment.
Essential Knowledge: 8.6.A.2
Keystone species, producers, and essential abiotic and biotic factors contribute to maintaining the diversity of an ecosystem.
Learning Objective: 8.6.B
Explain how the addition or removal of any component of an ecosystem will affect its overall short-term and long-term structure.
Essential Knowledge: 8.6.B.1
The effects of keystone species on the ecosystem are disproportionate relative to their abundance in the ecosystem. When they are removed from the ecosystem, it often collapses.
