Define Ecosystem
All the living things in an area and the way they affect each other and the environment.
Define Environment
The air, water, land in or on which people, animals and plants live. The conditions that affect a plant or animal in a habitat.
Define habitat
The natural environment in which an animal or plant normally lives.
Abiotic factors
Non-living factors in the environment.
Biotic factors
Living factors in an environment/
Define Food Chain
The flow of energy from organism to organism in a series of feeding relationships.
Define Food Web
The relationship between all the living things in a particular area, when thinking about how the eat each other. (multiple food chains).
Define Producer
An organism that is able to manufacture their own food (e.g. by the process of photosynthesis).
Define Consumer
Organism that must eat other organisms to get energy and nutrients they need.
Define Herbivore
Organism that consumes (eats) plants.
Define Carnivore
Organism that consumes (eats) meat.
Define Omnivore
Organism that consumes (eats) plants and meat.
Define Interdependence
Depending on each other for survival.
Define Predator
An animal that hunts, kills, and eats other animals.
Define Prey
An animal that is hunted and killed for food by another animal.
Define Competition
A situation in which the various organisms living in the same area try to compete for a limited supply of food, water, space.
Define Commensalism
A relationship between two species in which one gets an advantage from living closely with the other and the other is not affected by it.
Define Mutualism
A relationship between two organisms in which they live together and benefit each other.
Define Parasitism
A relationship between two organisms in which one benefits (parasite) and the other is harmed (host).
Define Host
A plant or animal that another plant or animal lives on as a parasite.
Define Parasite
An animal or plant that lives on or in another animal or plant of a different type and feeds from it
Define Adaptation
A characteristic that helps an organism survive in its environment.
