100

The difference between how matter and energy flow through the environment.

What is matter is recycled and energy flows in one direction from producers to consumers?

100
The process of water being absorbed into the ground.
What is infiltration?
200
Rain, snow, and hail are forms of ___.
What is precipitation?
200
These carbon reservoirs can be dug up from the ground and burned as a source of energy.
What are fossil fuels?
200

What are bacteria (bonus points for fungi)?

200

The way most animals acquire their Carbon and Nitrogen.

What is consuming food.

200

The carbon-based molecule produced by plants.

What is glucose?

300
The process that converts water vapor to liquid water and is responsible for creating clouds.
What is condensation?
300
The process by which carbon dioxide is released by a living organism into the atmosphere.
What is cellular respiration?
300

The process that some bacteria use to convert nitrogen gas from the atmosphere into a useable form of ammonia.

What is nitrogen fixation?

300

Three possible solutions to increase oxygen content in an ecosystem.

What are increasing the number of producers, increasing light for photosynthesis, and decreasing the number of consumers?

300
The process that involves water that is not absorbed into the ground, but instead runs along the surface.
What is surface run-off?
400
Evaporation of water from plant parts is called ___.
What is transpiration?
400

These living things perform cellular respiration to convert glucose into usable energy.

What are ALL living things (including plants)!

400

The most abundant element in the earth's atmosphere.

What is nitrogen?

400

Three ways to decrease Nitrogen-based waste in an ecosystem.

What are increase bacterial activity, remove consumers, increase number of producers, decrease decaying organic matter.

400

The process by which plants take in atmospheric carbon and release atmospheric oxygen.

What is photosynthesis?

500
A large reservoir of water below Earth's surface.
What is groundwater?

500

The process that some bacteria use to convert useable nitrates back into unusable nitrogen gas.

What is denitrification?

500

The primary cause of nutrient (carbon, nitrogen, oxygen, water) imbalance in nature.

What is human activity?
