Flashcard: Ecosystem Biology and Sustainability — 10 carte

Nitrogen cycle — key step?

Nitrogen fixation by bacteria

Ecosystem components?

Biotic and abiotic interacting components.

Food web — structure?

Interconnected feeding relationships

Photosynthesis — role?

Converts solar energy to chemical energy.

Photosynthesis — process?

Converts light energy to chemical energy

Food chains vs food webs?

Linear vs complex feeding relationships.

Energy transfer efficiency?

Approximately 10% between trophic levels.

Biogeochemical cycles?

Water, carbon, nitrogen cycles.

Limiting factors?

Regulate populations: resources, predation, competition.

Biodiversity — importance?

Vital for stability; loss leads to extinctions.
