Producers, primarily plants and algae, convert solar energy into chemical energy through photosynthesis. This chemical energy stored in organic molecules then flows through the ecosystem as consumers eat producers or other consumers.
The primary source of energy in an ecosystem is

- Which of the following is not true about the eco-system?
- Assertion (A): Unlike temperate forests, the tropical rain forests, if cleared, can yield productive farm-land that can support intensive agriculture for several years even without chemical fertilizers. Reason (R): The primary productivity of the tropical rain forest is very high when compared to that of the temperature forests.
