Ecological succession

• The evolution of a biological community over time
• The variability of living things on the planet
• When soil and rock are worn away by processes such as wind, rain, and glaciation
• The study of the interactions of organisms with their environment

Ecology

• The study of the interactions of organisms with their environment
• The increasing concentration of a substance as it moves up through the food chain
• When a body of water is inundated with nutrients and has an overgrowth of algae and plants, thereby decreasing the availability of dissolved oxygen
• The living organisms in a particular geographical area interacting with their non-living environment

Ecosystem

• The living organisms in a particular geographical area interacting with their non-living environment
• An ecological community adapted to particular climate conditions
• The linear relationship showing the flow of energy in an ecosystem
• The factors such as, physical, chemical, and biological that act upon an organism

Environment

• The factors such as, physical, chemical, and biological that act upon an organism
• The living parts of a planet
• The intertwining relationships showing the flow of energy in an ecosystem
• When soil and rock are worn away by processes such as wind, rain, and glaciation

Erosion

• When soil and rock are worn away by processes such as wind, rain, and glaciation
• The living components of an ecosystem
• The role a species plays in its environment
• When a body of water is inundated with nutrients and has an overgrowth of algae and plants, thereby decreasing the availability of dissolved oxygen

Eutrophication

• When a body of water is inundated with nutrients and has an overgrowth of algae and plants, thereby decreasing the availability of dissolved oxygen
• The maximum population size a part of the environment can hold for a particular species
• The movement of nutrients in an ecosystem
• The linear relationship showing the flow of energy in an ecosystem

Food chains

• The linear relationship showing the flow of energy in an ecosystem
• The long-term averages of temperature and precipitation
• The chemicals that are necessary for organisms to grow and survive
• The intertwining relationships showing the flow of energy in an ecosystem

Food webs

• The intertwining relationships showing the flow of energy in an ecosystem
• A group of organisms of different species living in a particular geographical area
• A layer of O3 molecules in the atmosphere that block some of the harmful UV rays from the sun
• The role a species plays in its environment

Niche

• The role a species plays in its environment
• A negative interaction between organisms over a limited resource
• The number of a group of the same organisms living in a particular geographical area
• The movement of nutrients in an ecosystem

Nutrient cycles

• The movement of nutrients in an ecosystem
• An organism that must obtain energy by ingesting and breaking down another organism
• The plants, plankton, and microbes which are capable of using the light energy of the sun to convert it to chemical energy
• The chemicals that are necessary for organisms to grow and survive
