Question

In food chains, the flow of energy is ALWAYS _________.
A) one-way.
B) reversible.
C) two-way.
D) uncontrolled.

Answer 1

A) one-way , explanation: the sun supports most of the earths ecosystems. Plants create chemical energy from abiotic factors that include solar energy. Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level.

Answer 2

In food chains, the flow of energy is always one way or unidirectional.

WHAT IS A FOOD CHAIN:

Food chain is a linear relationship that shows how organisms feed on one another to obtain energy in an ecosystem.

When an organism feeds on another organism, the energy is transferred. This flow of energy is however, unidirectional or one way.

This means that the energy flows in the direction of the producer (grass) to the tertiary consumer (frog) only.

Therefore, in food chains, the flow of energy is always one way or unidirectional.
