Quiz Answer Key and Fun Facts

1. By what process do plants create food?

Answer: Photosynthesis

Plants are not the only organisms to use photosynthesis; some bacteria do so as well.

2. What gas is a byproduct of the process that plants use to make food in nature?

Answer: Oxygen

Most of the world's oxygen supply comes from plants.

3. Plants need nitrogen in order to grow. Nitrogen in the air is not usable by plants. What is the most common process by which nitrogen is made available to plants?

Answer: Bacterial action

Many plants have nodules on their roots where nitrifying bacteria live.

4. What is an organism that breaks down dead organisms called?

Answer: Decomposer

Without decomposers, the Earth would be covered in many feet of dead stuff- yuck!

5. Ultimately, all of the energy in all life cycles on land originally came from the ...

Answer: Sun

Yep. The plants turned the sun's energy into food.

6. In what phase of the water cycle does rain fall?

Answer: Precipitation

Snow, sleet, and any other forms of water falling from the sky are also precipitation.

7. In the rock cycle, which kind of rocks are made from rocks that undergo heat and pressure?

Answer: Metamorphic rocks

Marble is an example of a metamorphic rock.

8. If a pesticide is released into the Arctic that accumulates in body cells, which of the following organisms is apt to have the highest pesticide levels?

Answer: Polar bear

The polar bear gets all the pesticide in the seals, which got all of the pesticide from the fish, which got it from the algae...

9. Under the surface of the Earth, hot molten rock rises, cools, then sinks. This process is called...

Answer: Convection

A convection oven uses the same principle!

10. The state in which organisms maintain internal equilibrium is called...

Answer: Homeostasis

Without this, they would quickly die.
