100

It has mass and takes up space

What is matter?

100

An organism that uses energy and matter from the environment to make its own food.

What is a producer?

100

A process in which atoms are rearranged to  produce new substances.

What is a chemical reaction?

100

A process that uses oxygen to release the energy stored in food molecules.

What is cellular respiration?

100

A pathway that energy and nutrients can follow through an ecosystem.

What is a food chain?

200

They are the building blocks of matter.

What are atoms?

200

An organism that gets its energy from breaking down the remains of other organisms that have died.

What is a decomposer.

200

It uses symbols to show the relationship between the starting materials and the materials produced in the chemical reaction.

What is a chemical equation?

200

Producers, consumers and some other types of organisms use this.

What is cellular respiration?

200

Interconnected food chains are called these.

What is a food web?

300

It is made up of two or more atoms.

What is a molecule?

300

An organism that gets its energy and matter from eating other organisms.

What is a consumer?

300

They are the building blocks of living things.

What are carbon molecules?

300

The first stage of cellular respiration takes place here.

What is the cytoplasm?

300

A representation of energy available at each level of a food web.

What is an energy pyramid?

400

Two hydrogen atoms and one oxygen atom makes this.

What is water?

400

Without these, matter that makes up organisms would not be recycled back to the nonliving environment.

What are decomposers?
400

It can form bonds with other carbon atoms or with different atoms

What is a carbon atom?

400

The second stage of cellular respiration takes place here.

What is the mitochondria?

400

It is essential to life becasue all cells are made up of these molecules.

What is the carbon cycle?

500

Oxygen and carbon are these.

What are elements?

500

Three things that use energy from sunlight to make sugar molecules.

What are plants, algae and bacteria.

500

A series of chemical reactions in which the cells of producers use energy from the sun to make carbon-based food molecules called sugars.

What is photosynthesis?

500

Energy is released these stages of cellular respiration

What is all stages?

500

Cells use this to build many molecules.

What is nitrogen?
