3. Population & Community Ecology

The maximum number of organisms in a particular population that an area can support.

All of the communities (biotic factors) and nonliving things

(abiotic factors) in a given area and the interactions among

them.

Two organisms fight over a mate. This is an example of

what type of interaction?

A large geographical area defined by climate and dominant plant and animal species.

All the pathways in a community that trace the flow of energy through trophic levels.

All offspring of a rabbit population survive and reproduce to the limits of its reproductive capability in the absence of limiting factors. This is an example of what type of growth?

Precipitation, fire, and freezing temperatures are examples of what type of limiting factors.

All the different species interacting with each other in a forest.

A type of interaction where one organism is harmed (could be death) and the other organism benefits.

• Commensalism

• Amensalism

• Mutualism

• Parasitism

• Predation

All the organisms involved benefit from the interaction.

• Commensalism

• Competition

• Mutualism

• Parasitism

• Predation
