Question

the flow of energy in an ecosystem is single​

Answer 1

Explanation:

Only 10% of energy is passed from one trophic level to the other. The energy that is obtained by the producers from the sun does not revert to the Sun and the energy passed to the herbivores does not return to the producers. ... Therefore, the flow of energy through an ecosystem is always 'one way'.

Answer 2

Answer:

plants gives energy from sun by process of photo synthesis so energy transfer from sun to plant ( producer ) . herbivores eat plants so energy transfer from plants to herbivores . carnivorous eats herbivores so energy transfer from herbivores to carnivorous .mixed consumer (omnivorous) eats carnivorous so energy transfer from carnivorous to omnivorous .apex consumer eats omnivorous so energy transfer from Omnivorous to apex consumer.

so energy is one way . energy transferition law :- energy nor be created nor be destory but it can transfer from one form to another so energy remains constant .
