Matter And Energy In Ecosystems Review Amplify

What is Cellular Respiration

• the ability to make things move or change

• the chemical reaction between oxygen and glucose that releases energy into the cells

• the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)

• The process of converting sunlight into chemical energy

What is photosynthesis

• a starting substance that is part of a chemical reaction

• an ending substance that is made during a chemical reaction

• a set of interacting parts forming a complex whole

• the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)

General Questions about the unit next. Type in ready to move on.

(a)  

Koalas are eating leaves on a sunny day. What is happening to the carbon in the air around the living things in the forest? Is carbon moving into the air, moving out of the air, or both?

• give off carbon to the air. Giving off carbon allows them to make energy storage molecules.

• give off carbon to the air. Giving off carbon uses up energy-storage molecules

• take in carbon from the air. The carbon is used to make energy-storage molecules

• take in carbon from the air. The carbon is used to break down energy storage molecules.

Saket has an aquarium with water, plants, and fish that eat the plants. It is sealed so no material can get in or out, and has glass sides that allow sunlight to come in. The aquarium can also be covered to prevent light from entering.

The amount of carbon in the aquarium’s water started out high. Now, the amount of carbon in the water is decreasing.

Is the aquarium now in sunlight or is it covered? What is happening to the number of energy storage molecules in the plants and fish as a result?

• The aquarium is now in sunlight, and there are more energy storage molecules in the plants and fish.

• The aquarium is now in sunlight, and there are fewer energy storage molecules in the plants and fish.

• The aquarium is now covered so no light can get in, and there are more energy storage molecules in the plants and fish.

• The aquarium is now covered so no light can get in, and there are fewer energy storage molecules in the plants and fish.

This tortoise is eating cacti on a sunny day. Is carbon moving into the air, moving out of the air, or both?

• Carbon is only moving into the air; it is not moving out of the air.

• Carbon is not moving into the air; it is only moving out of the air.

• Carbon is not moving anywhere

• Carbon is moving into the air and out of the air at the same time.
