Succession
What are the two types of succession
What is primary and secondary
the process of turning from liquid into vapor
What is evaporation
When nitrogen returns to the atmosphere
What is Denitrification
What are the two main processes that move carbon through the cycle
What is photosynthesis and respiration
Why is Phosphorous important for living organisms
What is gives them energy
A chemical substance that an organism needs to obtain from its environment in order to survive
What is Nutrient
The four main components of the water cycle
What is condensation, evaporation, precipitation, and transpiration
What do animals produce that returns nitrogen to the soil?
What is Waste
What gas is the main form of carbon in the atmosphere
What is the main reservoir of phosphorus in the environment
What is rocks/sediment
The first organisms, typically plants, to colonize a barren or disturbed area, initiating the process of ecological succession
What is Pioneer species
Water which collects as droplets on a cold surface when humid air is in contact with it
What is Condensation
The capture and conversion of nitrogen into a form that is useable by plants
What is Nitrogen Fixation
What process do plants use to absorb carbon dioxide
What is Photosynthesis
How does phosphorous return to the soil after an organism dies
What is decomposition
The stable, mature community that results when there is little change in species composition
What is Climax community
The continuous movement of water on earth's surface often seen between two bodies of water
What is runoff
Between 5 and 10 billion kg per year of Nitrogen is fixed by lightning strikes, but most fixation is done by
What is Bacteria
How does the concentration of carbon dioxide in the atmosphere affect climate?
What is heats it up
What process releases phosphorus from rocks
What is the exchange of matter through the biosphere
What is the Biogeochemical Cycle
The part of the leaf that releases water vapor back into the atmosphere
What do plants absorb from the soil to get nitrogen
What type of fuel releases carbon when burned
What is Fossil
Which human activity adds excess phosphorus to water bodies
What is fertilization
