The process by which primary producers use sunlight to convert carbon dioxide and water into sugars, releasing oxygen

An organism that can capture energy from the sun or chemicals and store it also called an autotroph

Organisms that rely on other organisms for energy and nutrients that are also called heterotrophs

An organism that breaks down nonliving matter into simple parts that can then be taken up and reused by primary producers

The process by which organisms use oxygen to release the chemical energy of sugars such as glucose, releasing carbon dioxide and water as a by-product

A linear series of feeding relationships

A visual map of feeding relationships and energy flow, showing the many paths by which energy and nutrients pass among organisms as they consume one another

The rank in a feeding hierarchy

is a process by which carbon is cycled between the atmosphere, land, water, and organisms.

can fix atmospheric nitrogen in to useful from called ammonia.

a process in which nitrogen is crucial between the atmosphere, soil, and organism depends upon these bacteria to supply nitrogen.

is the movement of phosphorus from the environment to organism and then back to the environment

is a gradual process of change and replacement of some or all the species in the community

The somewhat predictable series of changes in a community that follows a disturbance so serve that no vegetation or soil life remains

The somewhat predictable series of changes in a community that follows a disturbance

Species that colonize the newly exposed land first

is a final and stable community
