Study Notes
Phosphorus Cycle
- Phosphate is released into the soil and water through weathering of rocks and volcanic activity.
- Phosphorus in water can settle at the bottom of bodies or be incorporated into sediments.
Carbon Cycle
- Carbon moves from the atmosphere to plants through photosynthesis.
- Animals breathe out carbon dioxide as a waste product of respiration.
- Plants take in carbon dioxide during photosynthesis.
- Carbon is transferred from plants to animals through the food chain.
- Decay of organic matter releases carbon dioxide back into the air.
- Microorganisms break down organic matter, releasing carbon dioxide back into the air.
- Buried carbon from dead plants and animals becomes fossil fuels like coal, oil, and natural gas.
Nitrogen Cycle
- Nitrogen is converted to nitrogen gas through denitrification.
- Assimilation is the process by which organisms use nitrogen.
Respiration
- Respiration is the process by which organisms break down organic matter to release energy for cellular activities.
- Respiration supports diverse respiratory processes and maintains oxygen balance within ecosystems.
- Respiration is economically important to modern humans, in the form of fossil fuels.
