100
The 3 phases of the water cycle.
What is evaporation, condensation, and precipitation?
100
These are 2 ways carbon enters the atmosphere.
What is by breathing or respiration and combustion or burning?
100
The most important part of the nitrogen cycle.
What is bacteria?

Level 1of the Trophic Pyramid
What are producers?
100
The smallest branch of ecology
What is a species?
200
This is hot air
What is water vapor?
200
Carbon Dioxide is absorbed by
What is producers?
200
the process by which nitrogen is removed from the atmosphere and transformed into a biologically available substance is called
What is nitrogen fixation?
200
Level 2 of the Trophic Pyramid
What is the primary consumers?
200
The second level of the ecological hierarchy
What are populations?
300
When water vapor reaches cooler places they join together and again change into water.
What is condensation?
300
Carbon is passed along the food chain when
What is when animals feed on plants?
300
These are responsible for transforming the protein in the animal waste and dead plants and animals into biologically available nitrogen in soil.
What is nitrifying bacteria?
300
Level 3 of the Trophic Pyramid
What are secondary consumers?
300
Groups (populations) of different organisms inhabiting a location
What are communities?
400
When water droplets form bigger droplets and fall down from the sky.
What is precipitation?
400
The last stage of the carbon cycle.
What is The dead organisms (dead animals and plants) are eaten by decomposers in the ground? The carbon that was in their bodies is then returned to the atmosphere as carbon dioxide. In some circumstances, the process of decomposition is prevented. The decomposed plants and animals may then be available as fossil fuel in the future for combustion?
400
Nitrogen is released back into the atmosphere by
What is de-nitrifying bacteria?
400
Level 4 of the Trophic Pyramid
What is tertiary consumers?
400
All living organisms in an area and the nonliving factors of those places too.
What are ecosystems?
500
These are 2 ways that humans disrupt the water cycle.
What is reducing the amount of runoff that reaches the oceans? What is adding pollutants to the water which eventually shows up in rain?
500
2 ways humans negatively influence the carbon cycle.
What is burning fossil fuels? What is deforestation?
500
Ways in which humans disrupt the nitrogen cycle.
What is through the use of fertilizers and chemical additives in soil, and through the burning of fossil fuels?
500
An example of tertiary consumer

500
Parts of the planet that contain living organisms.
What are biospheres?
