A community of living things (plants; animals; microbes) interacting with each other and their non-living environment (air; water; soil).

A non-living part of an ecosystem such as sunlight; temperature; water; or soil.

A group of organisms that can breed and produce fertile offspring.

Any individual living thing like a plant; animal; fungus; or bacteria.

All the individuals of the same species living in a specific area.

The process by which plants and some other organisms use sunlight to make food (glucose) from carbon dioxide and water.

An organism like a plant or algae that makes its own food through photosynthesis.

An organism like fungi or bacteria that breaks down dead plants and animals and recycles nutrients back into the environment.

The process by which living things break down food (glucose) to release energy.

A simple sequence showing how energy and nutrients flow from one organism to another through eating.

A network of many connected food chains showing how different organisms eat and are eaten.

A step or level in a food chain or web (e.g. producers; herbivores; carnivores).

Ecological succession that starts in places where no life existed before like after a volcanic eruption.

Ecological succession that happens in an area where an ecosystem once existed but was disturbed like after a forest fire.

The first organisms (like mosses or lichens) to grow in a new or disturbed area during succession.

A stable mature ecosystem with little change in species over time reached at the end of succession.

The movement of carbon through living things; the atmosphere; oceans; and the Earth.

The process that moves nitrogen through the environment including bacteria turning nitrogen into forms plants can use.

The movement of phosphorus through rocks; water; soil; and living things.

Ecological succession

The natural gradual change in an ecosystem’s plants and animals over time.

Term	Definition
Ecosystem	A community of living things (plants; animals; microbes) interacting with each other and their non-living environment (air; water; soil).
Abiotic factor	A non-living part of an ecosystem such as sunlight; temperature; water; or soil.
Species	A group of organisms that can breed and produce fertile offspring.
Organism	Any individual living thing like a plant; animal; fungus; or bacteria.
Population	All the individuals of the same species living in a specific area.
Photosynthesis	The process by which plants and some other organisms use sunlight to make food (glucose) from carbon dioxide and water.
Producer	An organism like a plant or algae that makes its own food through photosynthesis.
Decomposer	An organism like fungi or bacteria that breaks down dead plants and animals and recycles nutrients back into the environment.
Cellular respiration	The process by which living things break down food (glucose) to release energy.
Food chain	A simple sequence showing how energy and nutrients flow from one organism to another through eating.
Food web	A network of many connected food chains showing how different organisms eat and are eaten.
Trophic level	A step or level in a food chain or web (e.g. producers; herbivores; carnivores).
Primary succession	Ecological succession that starts in places where no life existed before like after a volcanic eruption.
Secondary succession	Ecological succession that happens in an area where an ecosystem once existed but was disturbed like after a forest fire.
Pioneer species	The first organisms (like mosses or lichens) to grow in a new or disturbed area during succession.
Climax community	A stable mature ecosystem with little change in species over time reached at the end of succession.
Carbon cycle	The movement of carbon through living things; the atmosphere; oceans; and the Earth.
Nitrogen cycle	The process that moves nitrogen through the environment including bacteria turning nitrogen into forms plants can use.
Phosphorous cycle	The movement of phosphorus through rocks; water; soil; and living things.
Ecological succession	The natural gradual change in an ecosystem’s plants and animals over time.
