Circular. The flow of energy in the ecosystem is unidirectional. The energy enters the plants (from the sun) through photosynthesis during the making of food. This energy is then passed on to the successive trophic levels in a food chain is only 10% and rest energy get lost as heat during transfer and life process.

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.
Flow of energy in an ecosystem is always _____. View Solution. Q4
Nonliving things or abiotic things include air, water, land. It is composed of organisms interacting within communities. The driving force for an ecosystem is solar energy. Producers use solar energy to synthesize their food by the process of photosynthesis. From producers, the energy is transferred to herbivores.
Unidirectional flow of energy and cycling of nutrients are the two most basic characteristics of all ecosystems. In most of the natural ecosystems energy comes from the sun, it is trapped by producers and then passed on to successive trophic levels in the form of food. Thus, a long the food chain, there is a loss of energy and only 10 percent ...
The available energy decreases at higher trophic level. Out of the total energy available at a particular trophic level, only 10% is passed on to the next trophic level, making it impossible for energy to flow in the reverse direction. The flow of energy in an ecosystem occurs in the following sequence:
Plants absorb 2% of sun energy for photosynthesis. With each trophic level, only 10% energy is transferred and 90% is lost as heat in respiration. The longer the food chains, the lesser is the energy transfer efficiency. To increase the energy transfer efficiency, food chains must be smaller and consumers should directly feed on producers.
Energy flow in ecosystem:- We know that plants and photosynthetic bacteria (autotrophs), fix suns' radiant energy to make food from simple inorganic materials. All organisms are dependent for their food on producers, either directly or indirectly. So we find unidirectional flow of energy from the sun to producers and then to consumers.
According to the energy transfer law, only 10% of energy is transferred from one trophic level to the other. So, the energy that is captured by the producers does not revert back to the sun and the energy transferred to the herbivores does not come back to the producers. It just keeps on moving to the next trophic level in a unidirectional way.
