Question 7

A group of engineers has created a biodome filled with air, plants, and animals. No material can get in or out, but sunlight can get in during the daytime.The walls of the biodome are made of a material that absorbs and locks away carbon dioxide from the air so it is not available to the living things inside. What do you predict will happen to carbon in the air over time? How could this affect the living things in the dome?

Accepted Answer

Since the walls of the biodome absorb and lock away carbon dioxide from all living things, then eventually there will not be any carbon in the air and the plants will not be able to do photosynthesis.

Answer

The amount of carbon dioxide will increase in the air since the animals can do cellular respiration.

Answer

Nothing will happen and nothing will change

Question 8

A scientist built a model ecosystem that contains air, plants, and animals that eat those plants. The model ecosystem is sealed so no material can get in or out, but the glass sides allow light in when the scientist switches the light on. When the scientist switches the light off, the model ecosystem is in the dark.The number of energy storage molecules in the plants and animals inside the model ecosystem started out high.Then the number of energy storage molecules began to decrease. Was the decrease because the light was switched on or because it was switched off? What happened to the amount of carbon dioxide in the air?

Accepted Answer

he scientist switched the light off, and there is more carbon dioxide in the air.

Answer

The scientist switched the light on, and there is less carbon dioxide in the air.

Answer

The scientist switched the light off, and there is less carbon dioxide in the air.

Question 17

Mr. Horris has a glass cube filled with water that contains tiny plants and fish that eat those plants. Nothing can get in or out, but light can get through the glass when it is placed in light. The number of ESMs in the plants and shrimp started out high, but then the glass cube was moved, and the number of energy storage molecules decreased. Was the glass cube moved into the light or into the dark? What happened to the amount of carbon in the water?
