NEET BIOLOGY

Detailed explanation-1: -Explanation: This is because in a food chain, energy flow from one trophic level to another. The producer which include plants are the source of energy which they manufacture good in the presence of light energy from sun.

Detailed explanation-2: -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.

Detailed explanation-3: -The flow of energy in the ecosystem is unidirectional because the energy lost as heat from the living organisms of a food chain cannot be reused by plants in photosynthesis. During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the path.

Detailed explanation-4: -Which statement is correct with respect to the food chain? All the chains formed by nutritional relations is used to understand energy flow.

Detailed explanation-5: -According to the First Law of Thermodynamics, energy is neither created nor destroyed and only transferred or converted from one form to another. This principle holds true in ecosystems, where energy is constantly transferred across the food web.
