The complex network of related food chains within an ecosystem.
Food web
A naturally occurring chemical compound composed of two oxygen atoms connected to a single carbon atom.
Carbon dioxide
All living things in a place and their relation to their environment.
Ecosystem
Plants or animals that take over in areas where they do not normally live.
Invasive
Bonus:
Place where animals or plants live and interact.
Habitat
A large community of plants and animals that occupy a distinct region such as a desert, a rainforest, or a freshwater lake.
Biome
An animal that feeds on organisms that have already died or that have been killed by another animal.
Scavenger
In form of nutrients and sunlight is what sustains plants and animals in living.
Energy
Substances such as proteins, minerals, or vitamins that are needed by people, animals, and plants to stay strong and healthy.
Nutrients
Relating to non-living organisms.
Abiotic
A graphical representation designed to show the number of animals in a food web.
Pyramid
The green substance in plants that uses light to manufacture food from carbon dioxide and water.

Carnivore
Relating to living organisms.
Biotic
An animal that eats both plants and meat.
Omnivore
An environmental factor that affects the survival of living things and restricts the size of a population.

A naturally occurring chemical compound composed of two oxygen atoms. It is normally found in its gas form.
Oxygen
An animal that only eats plants.
Herbivore
An ordered arrangement of animals and plants in which each feeds on the one below it in the chain.
Food chain
An organism, often a bacterium or fungus, that feeds on and breaks down dead plant or animal matter.
Decomposer
The specific role that a plant or animal has within an ecosystem.
Niche
A chemical process by which green plants and some other organisms make their food. Plants use energy from the Sun to turn water and carbon dioxide into food, and they produce oxygen as a by-product .
Photosynthesis
A group of living things that share certain traits and can produce offspring.
