2.1 Species & Populations

2.1 Species & Populations NOTES

Significant Ideas:

• A species interacts with its abiotic and biotic environments, and its niche is described by these interactions.

• Populations change and respond to interactions with the environment.

• Any system has a carrying capacity for a given species.

Applications & Skills:

• Interpret graphical representations or models of factors that affect an organism's niche. Examples include predator-prey relationships, competition, and organism abundance over time.

• Explain population growth curves in terms of numbers and rates.
