An Ecosystem is a community and its physical environment together. All the populations of organisms living together in an environment make up a community.
A niche describes how the species meet its needs and how it affects other organisms. For example: Salt grass provides a home for snails to live on. Salt grass also provides protection for baby fish and shrimp among its underwater stems.
Every organism has adaptations that help it compete for resources. For example: a cheetah has speed so it can captures its prey.
A place in an ecosystem where a population lives. For example frogs live in ponds. That is its habitat.
This is when an organism or animal no longer exists. It was wiped out.
Where animals compete for the resources in an ecosystem such as food. Animals are in competition for the same food. For example: Hyenas and Cheetahs hunt the same type of animals for food.
Behavior that an organism inherits. For Example: Animals have an instint to survive or protect themselves from danger.
Everything a living organism needs in order to survive. For example: food, soil, weather, landform, air, and water.

Chemicals used to kill a wide variety of unwanted plants or animal pests. The use of these chemicals can damage the ecosystem.
All the individuals of the same kind of living thing in the same environment. For example: A mound of ants in an ant hill.

The path of food from one living thing to another.
A living thing that eats other living things. All animals are consumers.
What are the parts of an ecosystem?
Community (all the populations that live there)
Habitat (home where the animal lives)
Everything around a living thing.
A living thing that breaks down dead things for food.
