Question

write the direction of flow of energy in an ecosystem​

Answer 1

Answer:

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.

Answer 2

The direction of flow of energy in an ecosystem​

Explanation:

• Energy flow in an ecosystem is unidirectional.

Plants obtain energy from the Sun and transform it into chemical energy through the process of photosynthesis.

This energy is then transformed further in herbivores and carnivores at various trophic levels.

In these animals, the chemical energy is mostly transformed into mechanical energy and heat.

The heat part is lost to the atmosphere at each trophic level.

At each trophic level about 90 percent of the energy is used up and only 10 percent of the energy is transferred to the next trophic level.
