2.6 Adaptations

Describe how organisms adapt to their environment.

• Organisms adapt to their environment over time, both in short- and long-term scales, via incremental changes at the genetic level.
• Environmental changes, either sudden or gradual, may threaten a species’ survival, requiring individuals to alter behaviors, move, or perish.
• Enduring understanding ERT-2: Ecosystems have structure and diversity that change over time.
