Ecology, Mr. Bruton

Abiotic factor The nonliving parts of an organism’s environment.
biological community is made up of interacting populations in a certain area at a certain time.
biosphere is the portion of Earth that supports living things. It extends from high in the atmosphere to the bottom of the oceans.
biotic factor All the living organisms that inhabit an environment
commensalism is a symbiotic relationship in which one species benefits and the other species is neither harmed nor benefited.
Ecology is the study of interactions that take place between organisms and their environment.
ecosystem is made up of interacting populations in a biological community and the community’s abiotic factors.
Habitat is the place where an organism lives out its life.
Mutualism A symbiotic relationship in which both species benefit
niche is all strategies and adaptations a species uses in its environment—how it meets its specific needs for food and shelter, how and where it survives, and where it reproduces.
Parasitism A symbiotic relationship in which a member of one species derives benefit at the expense of another species
Population is a group of organ- isms, all of the same species, which interbreed and live in the same area at the same time.
Symbiosis The relationship in which there is a close and permanent association between organisms of different species
Autotroph An organism that uses light energy or energy stored in chemical com- pounds to make energy-rich compounds is a producer
Biomass is the total weight of living matter at each trophic level.
Decomposer break down the complex compounds of dead and decaying plants and animals into simpler molecules that can be more easily absorbed.
Food Chain is a simple model that scientists use to show how matter and energy move through an ecosystem.
Food Web shows all the possible feeding relationships at each trophic level in a community.
Heterotroph An organism that cannot make its own food and feeds on other organisms
Trophic Level Each organism in a food chain rep- resents a feeding step
