Biodiversity and Ecosystem Stability

Biodiversity and Ecosystem Stability

What is it?

Biodiversity includes genetic, species and ecosystem variety. It supports ecosystem functions and options for recovery, although stability depends on interaction patterns as well as species count.

In simple words

• Biodiversity includes genetic, species and ecosystem variety. It supports ecosystem functions and options for recovery, although stability depends on interaction patterns as well as species count.
• Understanding biodiversity and ecosystem stability connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.
• A complete answer on biodiversity and ecosystem stability links the starting condition to its mechanism and outcome.

Important terms

Biodiversity and ecosystem stability: Biodiversity includes genetic, species and ecosystem variety. It supports ecosystem functions and options for recovery, although stability depends on interaction patterns as well as species count.

Mechanism: Start with the trigger or starting condition, follow the biological structures and signals in order, and finish with the response or product. For biodiversity and ecosystem stability, the central relationship is: Biodiversity includes genetic, species and ecosystem variety. It supports ecosystem functions and options for recovery, although stability depends on interaction patterns as well as species count.

Biological significance: Understanding biodiversity and ecosystem stability connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.

What you should learn

• Define biodiversity and ecosystem stability in accurate biological language.
• Explain the mechanism or relationship involved in biodiversity and ecosystem stability.
• Apply biodiversity and ecosystem stability to a comparison, prediction or Federal Board exam question.

Examples

• Identify the starting condition
• Name the active structure or molecule
• Trace the direction of change
