A relationship within certain populations that work together for a common goal.

• Community

• Competition

• Cooperation

• Commensalism

The part of the Earth where living organism are found.

• Biosphere

• Community

• Population

• Ecosystem

The maximum number of organisms that can be supported in a given environment.

• Climax Community

• Limiting Factor

• Exponential Growth

• Carrying Capacity

A symbiotic relationship in which only one species benefits but the other is neither helped nor harmed.

• Commensalism

• Symbiosis

• Mutualism

• Parasitism

Match the following

• Climax Community

• A stable and mature community

• Immigration

• An animal that eats only other animals

• Herbivore

• A process in which individuals enter a population

• Carnivore

Match the following.

• Limiting Factor

• A community of living organisms plus their nonliving environment.

• Community

• All the different populations of different species living in the same place at the same time.

• Competition

• Things that limit how many organisms can live in a population.

• Ecosystem

• An area with distinct characteristics where an organism lives.

• Habitat

• The interaction among organisms to better obtain resources or mating opportunities over others in order to survive.
