What is the term for a relationship where both species benefit?

• Parasitism

• Commensalism

Identify the relationship where one organism benefits and the other is neither helped nor harmed.

• Mutualism

• Parasitism

• Commensalism

• Predation

Analyze how limiting factors can influence the carrying capacity of an ecosystem.

• Limiting factors increase the carrying capacity by providing more resources.

• Limiting factors decrease the carrying capacity by restricting resources.

• Limiting factors have no effect on carrying capacity.

• Limiting factors only affect non-living components of the ecosystem.
