Question

choose the correct option , in a food chain ,there is (a) bidirectional flow of energy (b) zig zag flow of energy (c) multi directional flow of energy (d) unidirectional flow of energy.

​

Answer 1

Answer:

(d). unidirectional flow of energy.

The flow of energy in an ecosystem is always linear ie uni direction. At each energy step in food chain, the energy received by the organisms is used for its own metabolism and maintenance. The left over energy is passed to next higher trophic level. Thus the energy flow decreases with successive trophic level.

Answer 2

(d)$\large\bf\red{Unidirectional\: flow\: of\: energy}$

$\large\mathfrak\blue{Explanation☞}$

The flow of energy is from prey to predator and it cannot be in the reverse direction. Hence the flow of energy is unidirectional.
