Explain the biogeochemical/nutrient cycle and how nutrients flow between reservoirs.

<p>The biogeochemical/nutrient cycle refers to the path that atoms take from the living (biotic) to the non-living (abiotic) world and back again. Nutrients (elements) can flow between reservoirs through a variety of pathways.</p> Signup and view all the answers

Describe the role of plants in the water cycle and how water is returned to the atmosphere.

<p>Plants absorb water through their roots for photosynthesis and release water through transpiration. This water returns to the atmosphere.</p> Signup and view all the answers

What are the percentages of nitrogen gas (N2), oxygen gas (O2), and other gases in the atmosphere?

<p>78% nitrogen gas (N2), 21% oxygen gas (O2), and 1% other gases (H2O, CO2, N2O).</p> Signup and view all the answers

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.
