Answer 1

Answer:

hus, the correct answer is 'Both Assertion and Reason are correct

Explanation:

Energy flow is the amount of energy that flows from one trophic level to another trophic level in an ecosystem. It is unidirectional. In any given ecosystem, flow of energy occurs through different trophic levels. Producers or plants obtain their energy from the sun by photosynthesis. The primary consumers (herbivores) obtain their energy from the producers. The secondary consumers (carnivores) obtained their energy by using herbivores as a source of food and so on.  The energy present at each successive trophic level is 10% of the previous trophic level. The energy is released into the atmosphere in the form of heat energy. It cannot be reused.
