A researcher claims that studying a single isolated ecosystem is sufficient to understand the global biosphere. Which of the following is the strongest counter-argument to this claim?
- 1Ecosystems are closed systems that do not exchange matter with others.
- 2The biosphere relies on essential linkages among ecosystems via global biogeochemical cycles of matter and energy flows.✓
- 3The biosphere contains only terrestrial ecosystems, so studying one forest ecosystem is adequate.
- 4Individual organisms only, not ecosystems, determine biosphere-level processes.
Correct answer
The biosphere relies on essential linkages among ecosystems via global biogeochemical cycles of matter and energy flows.
