Ecosystems Review

The term "organism" is what is used to refer to:

• A place where living & non-living things interact with each other

• The process where certain organisms use water, sunlight, & carbon dioxide to produce their own food

• One of the non-living parts of an ecosystem

• An individual living thing

A habitat is:

• The location in which an organism lives, and which provides the organism everything that it needs to survive

• The process where certain organisms use water, sunlight, & carbon dioxide to produce their own food

• A non-living part of an ecosystem

• A living part of an ecosystem

A biotic factor in an ecosystem is:

• A living part of that ecosystem

• A non-living part of that ecosystem

• The process where certain organisms use water, sunlight, & carbon dioxide to produce their own food

• The location in which an organism lives, and which provides the organism everything that it needs to survive

An abiotic factor in an ecosystem is:

• A living part of that ecosystem

• A non-living part of that ecosystem

• The process where certain organisms use water, sunlight, & carbon dioxide to produce their own food

• The location in which an organism lives, and which provides the organism everything that it needs to survive

What are resources in an ecosystem?

• A living part of that ecosystem

• The things that an organism gets from its environment which it needs in order to survive, grow, & reproduce

• The process where certain organisms use water, sunlight, & carbon dioxide to produce their own food
