The release of energy from glucose or another organic substrate in the presence of oxygen.

The release of energy from glucose or another organic substrate in the absence of oxygen.

Organisms that convert inorganic forms of energy to organic forms of energy.

the rate at which energy is used by an organism at complete rest

process by which tissue concentrations of chemicals in organisms at one trophic level exceed tissue concentrations in organisms at the next lower trophic level in a food chain

The mass of a species or group of species.

Animals that eat other animals for energy

Organisms that get food energy from dead parts of other organisms.

Organisms that eat detritus

Dead or decaying organic matter that is consumed by detritivores

The percentage of energy from one trophic level that is incorporated in the next level; consistent with the second principle of thermodynamics

Animals that obtain most of their body heat from the environment.

Animals that obtain most of their body heat from internal metabolic processes.

A diagram that compares the amount of energy available at each position, or level, in the feeding order.

The simplest representation of energy flow in a community

Interconnected feeding relationships in an ecosystem.

Organisms in the second trophic position that eat autotrophs.

A state in which the metabolic rate slows by as much as 99 percent.

An evolutionary strategy in which organisms allocate a relatively small fraction of their energy budget toward reproduction.

The use of energy to maintain order in a living system.

A growth process in which juveniles increase in size and change in form to the point at which they are capable of reproduction.
