• Biology

• Science

• Ecology

• Zoology

the natural home or environment of an animal, plant, or other organism.

• Habitat

• Niche

• Community

• Biome

Largest number of individuals of a population that a environment can support

• Limiting Factors

• Population Peak

• Carrying Capacity

• Exponential Growth

All the different populations that live together in an area

• Community

• Population

• Ecosystem

• Organism

An ecological succession that begins in an area where no biotic community previously existed

• Primary Succession

• Secondary Succession

• Tertiary Succession

• Climax Community

A limiting factor of a population wherein large, dense populations are more strongly affected than small, less crowded ones. (examples include disease, predation, and competition for resources)

• Density dependent factor

• Density independent factor

• Growth factor

• Growth promoter

A relationship between two organisms of different species where one benefits and the other is harmed (+/-)

• Mutualism

• Parasitism

• Commensalism

• Competition

Full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions

• Habitat

• Niche

• Ecosystem

• Limiting Factor

the struggle between organisms to survive in a habitat with limited resources. It becomes more intense if their niches are similar.

• Competition

• Mutualism

• Predation

• Parasitism

organism that obtains energy from the foods it consumes; also called a consumer

• Omnivore

• Heterotroph

• Autotroph

• Decomposer
