Study Notes
Composition of the Atmosphere
- CO2 and O2 are found in the atmosphere, with O2 making up approximately 21% and CO2 making up a small percentage.
- The atmosphere is composed of 78% nitrogen gas (N2), 21% oxygen gas (O2), and small percentages of other gases.
Law of Conservation of Matter
- The Law of Conservation of Matter states that matter cannot be created or destroyed, only converted from one form to another.
Nutrient Uptake by Plants
- Plants draw up nutrients (elements) from the soil.
Disease Transmission
- The source of transmission for diseases is not specified in the text.
Water Cycle
- Evaporation and condensation cause water vapor to cool and fall to earth as rain.
Biogeochemical/Nutrient Cycle
- The biogeochemical/nutrient cycle involves the flow of nutrients between reservoirs, including the soil, atmosphere, and living organisms.
- Nutrients are drawn up by plants from the soil, used by living organisms, and eventually returned to the soil through decomposition.
Plant Role in Water Cycle
- Plants play a crucial role in the water cycle by releasing water vapor into the atmosphere through transpiration.
- Water is returned to the atmosphere through transpiration, allowing the water cycle to continue.
Gas Cycles
- Inorganic gases, such as CO2 and O2, cycle through living things through processes including photosynthesis and respiration.
- CO2 is taken up by plants during photosynthesis and released back into the atmosphere through respiration.
Condensation and Precipitation
- Condensation occurs when water vapor in the air cools and changes state from a gas to a liquid.
- Precipitation occurs when condensed water droplets in the air become too heavy to remain suspended, falling to the earth as rain.
