Chapter 3.3 Cycles In Nature Flashcards
How does matter move among the living and nonliving parts of an ecosystem?
Matter is recycled within and between ecosystems through biogeochemical cycles.
What are biogeochemical cycles?
Elements, compounds and other forms of matter are passed from one organism to another and from one part of the bioshpere to another
What do biogeochemical cycles connect?
Biological, geological and chemical aspects
What are the componencts of the water cycle?
Condensation Transpiration Evaporation Precipitation Runoff Percolation
What is the energy source of the water cycle?
The sun
What are the components of the carbon cycle?
Carbon dioxide (CO2) in the atmosphere Photosynthesis Food Waste Respiration Fuel combustion Decomposition
What four processes move carbon?
- Biological processes such as photosynthesis, respiration and decomposition
- Burial and decomposition of dead organisms and their conversion under pressur (fossil fuel)
- Geochemical processes such as erosion and volcanic activity release CO2
- Mining, cutting and burning forests, burning fossil fuels
What are two other cycles in nature?
Nitrogen cycle
Phosphorous cycle
Where is nitrogen found?
The main reservoir is the atmosphere.
It is also cycles through the soil and tissues of living organisms.
Where does phosphorous cycle?
Among the land, ocean sediments and living organisms
