Carbon cycle: Ecology The combined processes, including photosynthesis, decomposition, and respiration, by which carbon as a component of various compounds cycles between its major reservoirs—the atmosphere, oceans, and living organisms.
Carrying Capacity: The maximum number of persons or things that a vehicle or a receptacle can carry
Cellular Respiration: The series of metabolic processes by which living cells produce energy through the oxidation of organic substances.
Consumer: An organism that generally obtains food by feeding on other organisms or organic matter
Dependent Variable: A dependent variable is what you measure in the experiment and what is affected during the experiment
Ecological Niche: the status of an organism within its environment and community
ecosystem: An ecological community together with its environment, functioning as a unit
