100

All the living and nonliving parts in an area.

What is an ecosystem?

100
The process by which plants use sunlight to make sugar from water and carbon dioxide.
What is photosynthesis?
100

Diagram that compares the amount of energy available at each level in the feeding order.

What is an energy pyramid?

100
Evaporation, condensation, precipitation.
What is the water cycle?
100

Non-living factors.

What are abiotic factors?

200

The place where a species live.

What is a habitat?

200

An organism that uses sunlight as energy.

What is a producer?

200
A combination of all food chains in a community.
What is a food web?
200
This element is a part of all proteins and makes up 80% of the air we breathe.
What is nitrogen?
200

All the populations living together in one area.

What is a community?

300

The role of a species in an ecosystem.

What is a niche?

300
Consumer that gets its energy from other consumers.
What is a carnivore?
300
Organisms at each level of the energy pyramid eat those in these levels.
What are the levels below them?
300
Opposite of photosynthesis.
What is respiration?
300
Consumers that get their energy from producers and consumers?
What is an omnivore?
400
Feeds on bodies of recently dead organisms.
What is a scavenger?
400
Include fungi and other single celled organisms.
What is a decomposer?
400

Energy in an energy pyramid is lost as this.

What is heat?

400
This is how animals return water to their ecosystem.
What is through their waste?
400
During respiration, organisms produce these 2 things.
What is carbon dioxide and water?
500
These tiny organisms carry out most of the photosynthesis on the earth.
What is plankton?
500
Consumers give off this that producers need.
What is carbon dioxide?
500
A food web clearly shows how organisms are independent/dependent on each other.
What is dependent?
500
How nitrogen compounds can be turned back into nitrogen gas.
What is through bacteria in soil?
500
This can cause nitrogen gas in the air to combine with other substances to form nitrogen compounds.
What is lightning?
