Ecology Review 1

Water is constantly moving between the atmosphere & Earth.

• Water Cycle

• Carbon Cycle

• Nitrogen Cycle

• Phosphorus Cycle

4 main processes move carbon:

• Water Cycle

• Carbon Cycle

• Nitrogen Cycle

• Phosphorus Cycle

The atmosphere is the main reservoir of nitrogen; it also cycles through the soil and tissues of living organisms.

• Water Cycle

• Carbon Cycle

• Nitrogen Cycle

• Phosphorus Cycle

Phosphorus in biosphere cycles among the land, ocean sediments and living organisms

• Water Cycle

• Carbon Cycle

• Nitrogen Cycle

• Phosphorus Cycle

Select all the ways that Move Carbon (Select ALL that apply)

• Biological processes, such as photosynthesis, respiration and decomposition

• Burial and decomposition of dead organisms and their conversion under pressure (fossil fuel)

• Geochemical processes, such as erosion and volcanic activity release CO2

• Mining, cutting and burning forests, burning fossil fuels

Nitrogen is _________ abundant element found in the earth’s atmosphere

• Most

• Least

How do Humans Impact The Phosphorus Cycle (CLICK ALL THAT APPLY)

• Humans can alter the phosphorus cycle by the cutting of tropical rain forests

• Agricultural runoff provides much of the phosphate found in waterways

• Humans Pave over land

• Humans Burn Coal

The Phosphorus Cycle does not include which state of matter?

• Solid

• Liquid

• Gas

Which Spheres does the Phosphorus Cycle not play a significant role in?

• Biosphere

• Hydrosphere

• Geosphere

• Atmopshere

Study of the interactions among organisms and between organisms and their environment

• Ecology

• Biology

• Environmental

• Meteorology
