Environmental Science Chapter 5

the process by which organisms use oxygen to release the chemical energy of sugars producing carbon dioxide and water.

• Food Chain

A linear series of feeding relationships of organisms.

• Food Chain

a diagram that shows the feeding relationships and energy flow of possible paths in which nutrients pass from organism to organism in an ecosystem.

• Phosphorous Cycle

• Nitrogen Cycle

• Food Chain

• Food Web

the process in which plants algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen.

• Phosphorus Cycle

• Cellular Respiration

• Photosynthesis

• Eating

a species that colonizes an uninhabited area and that starts an ecological cycle in which many other species become established.
