- Photosynthesis
- the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen
- Producer
- an organism that can make organic molecules from inorganic molecules; a photosynthetic or chemosynthetic autotroph that serves as the basic food source in an ecosystem
- Consumer
- an organism that eats other organisms or organic matter instead of producing its own nutrients or obtaining nutrients from inorganic sources
- Decomposer
- an organism that feeds by breaking down organic matter from dead organisms; examples include bacteria and fungi
- Cellular Respiration
- the process by which cells produce energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide
- Food Chain
- the pathway of energy transfer through various stages as a result of the feeding patterns of a series of organisms
- Food Web
- a diagram that shows the feeding relationships between organisms in an ecosystem
- Trophic Level
- one of the steps in a food chain or food pyramid; examples include producers and primary, secondary, and tertiary consumers
- Carbon Cycle
- the movement of carbon from the nonliving environment into living things and back
- Nitrogen Cycle
- the process in which nitrogen circulates among the air, soil, water, plants, and animals in an ecosystem
- Phosphorus Cycle
- the cyclic movement of phosphorus in different chemical forms from the environment to organisms and then back to the environment
- Ecological Succession
- a gradual process of change and replacement in a community
- Primary Succession
- succession that begins in an area that previously did not support life
- Secondary Succession
- the process by which one community replaces another community that has been partially or totally destroyed
- Pioneer Species
- a species that colonizes an uninhabited area and that starts an ecological cycle in which many other species become established
- Climax Community
- a final, stable community in equilibrium with the environment
