Study Notes
Ecosystems: Cycles of Matter
- Transpiration: Water evaporates from plant leaves, returning to the atmosphere.
- Oxygen-Carbon Cycle: Living things use energy and release gas as waste. This cycle explains the circulation of these gases.
- Nitrogen Cycle: A continuous circulation between soil, organisms, and air.
- Water Cycle: Includes water vapor changing from gas to liquid (condensation).
- Nitrogen in the Soil: Plants absorb nitrogen from the soil; animals consume plants for nitrogen intake. Animals do not directly absorb nitrogen from the soil.
-
Water Cycle Steps (in order):
- Energy from the sun causes water to evaporate.
- Water vapor cools and condenses to form clouds.
- Droplets combine in clouds to grow larger.
- Large water droplets fall to the ground.
- Photosynthesis & Respiration: Green plants use sunlight, water, and carbon dioxide to create food, releasing oxygen. Animals utilize oxygen for energy, releasing carbon dioxide as waste.
- Runoff: Rainwater flowing over Earth's surface, gathering in lakes and rivers.
