Food Chains/Webs
Feeding level in a food chain or web
What is trophic level?
Biomass produced over time in an ecosystem
What is productivity
Phase of the water cycle where water returns from the atmosphere to Earth
What is precipitation
Form of atmospheric carbon
Carbon dioxide
Type of succession that occurs in an area that has never had soil
What is primary succession
Organism that fixes energy
What is primary producer
Total amount of energy fixed during photosynthesis
What is gross primary productivity
Phase of the water cycle where water flows down a hill back to a body of water
What is surface run off
A natural structure that holds more carbon than it releases
What is carbon sink
Type of succession that occurs after a disturbance
What is secondary succession
Process by which producers fix energy
What is photosynthesis
Form of carbon taken in to be used during photosynthesis
Phase of the water cycle where water goes INTO the soil
Infiltration
Step of the carbon cycle where carbon is fixed from an unusable to a usable form
What is photosynthesis
The slower of the two types of succession
What is primary succession
How much energy gets passed to the next trophic level (on average)
What is 10%
Graphical representation of the mass of each trophic level in an ecosystem
What is pyramid of biomass
Phase of the water cycle where water moves THROUGH the soil
Through flow
Three steps of the carbon cycle that plants directly contribute to
Photosynthesis, respiration, decomposition
Species that first move in during succession
What is pioneer species
Highest number of trophic levels that can be observed in a marine ecosystem
What is 5
The amount of energy a producer fixes minus what it needs to live
What is net primary productivity
Phase of the water cycle where precipitation is caught by plants or ground litter
Interception
Step of the carbon cycle ALL living things contribute to
What is respiration
Final stage of succession
