3 important questions on The flux of energy and matter through ecosystems - The flux of matter through ecosystems - Nutrient budgets in terrestrial ecosystems
What are the sources of the carbon and nitrogen content of terrestrial communities?
Carbon dioxide and gaseous nitrogen from the atmosphere.
Rain contains chemicals derived from which 3 sources?
- Trace gasses, such as oxides of sulfur ans nitrogen.
- Aerosols, produced when tiny water droplets from the oceans evaporate in the atmosphere and leave behind particles rich in sodium, magnesium, chloride and sulfate.
- Dust particles from fires, volcanoes and windstorms, often rich in calcium, potassium and sulfate.
What links the nutrient budget of terrestrial and aquatic communities?
- The movement of water under the force of gravity.
- Terrestrial systems lose dissolved nutrients into streams and ground waters; aquatic systems gain nutrients from streamflow and underground water discharge.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
