2. Water becoming liquid (or solid) and falling from clouds.

1. What is evaporation?

2. What is precipitation?

200

1. Water going from the soil to groundwater due to gravity.

300

Nitrogen cycle in an aquarium. (4 steps)

What is 1. Decomposers -> Ammonia, 2. Bacteria fix Ammonia -> Nitrite, 3. Bacteria fix Nitrite -> Nitrate, 4. Water Changes get out Nitrate?

400

1. Can use Nitrate in an aquarium.
