What organism relies on complex organic substances for nutrition?
How does carbon enter the biotic part of the ecosystem?
Carbon enters the biotic (living) part of the ecosystem through photosynthesis. Plants of the forests take the carbon in carbon dioxide and fix it in organic compound such as sugar, starch, cellulose and other carbohydrates. Respiration in plants returns carbon dioxide to the atmosphere.

How does energy move in ecosystem?
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next
How does energy leave the ecosystem?
Cycling Energy Energy does not cycle the way nutrients and atoms do. Energy enters the ecosystem from the Sun and exits after the organisms have taken as much as they need. Organisms release energy back into the biosphere as heat. Energy is different in that it comes into the biosphere and then leaves.
What controls the number of trophic levels in an ecosystem?
Explanation: In all ecosystem, first base level of pyramid will be occupied by producers, consumers occupy higher trophic levels. Energy is lost when it is transferred from one trophic level to the next. Approximately 10% of the stored energy of a trophic level could be transferred to the consumers of next level.
