Science Quiz: Interactions in the Environment

A producer is:

• The non-living things in an ecosystem.

• A living organism that makes its own food through the process of photosynthesis.

• A system of interconnected food chains in an ecosystem.

• Organisms that need to eat other organisms to get energy.

A population is:

• When an ecosystem in sustainable/stable equilibrium.

• The wide range of living organisms on Earth.

• The natural home of an animal or plant to which they are adapted. (desert, pond, rain forest)

• The number of a specific organism in a particular area

A habitat is:

• The natural home of an animal or plant to which they are adapted.

• The living things in an ecosystem.

• A variety of living organisms interacting with each other in a specific ecosystem.

• The ability of an ecosystem to maintain a survivable balance independent of outside help.

Ecological balance is:

• Is when organisms reinhabit an area that once had, or still has living organisms on it.

• Is when organisms gradually come to inhabit an area that has no, and has never had any living things on it.

• A system of interconnected food chains in an ecosystem

• When an ecosystem in sustainable/stable equilibrium.

Biotic refers to:

• The living things in an ecosystem.

• The non-living things in an ecosystem.

• The ability of an ecosystem to maintain a survivable balance independent of outside help.

• A non-native organism introduced to a habitat that does harm to the organisms native to the habitat.

Abiotic refers to:

• The living things in an ecosystem.

• The non-living things in an ecosystem,

• An organism that in imminent danger of extinction.

• A non-native organism introduced to a habitat that does harm to the organisms native to the habitat.

A decomposer is:

• Organisms that need to eat other organisms to get energy.

• A living organism that makes its own food through the process of photosynthesis.

• A living organism that breaks down dead matter to return nutrients to the carbon cycle.

• A non-native organism introduced to a habitat that does harm to the organisms native to the habitat.

Biodiversity is:

• The ability of an ecosystem to maintain a survivable balance independent of outside help.

• A community consisting of the living and non-living things in an environment, and their interactions.

• Is when organisms reinhabit an area that once had, or still has living organisms on it.

• The wide range of living organisms on Earth.

Sustainability is:

• The ability of an ecosystem to maintain a survivable balance independent of outside help.

• When an ecosystem in sustainable/stable equilibrium.

• A variety of living organisms interacting with each other in a specific ecosystem.

• A system of interconnected food chains in an ecosystem.

A food web is:

• The wide range of living organisms on Earth.

• The natural home of an animal or plant to which they are adapted.

• A system of interconnected food chains in an ecosystem.

• A variety of living organisms interacting with each other in a specific ecosystem.
