Answer: energy flows in one direction, and nutrients recycle.
Explanation:
The options are:
• energy flows in one direction, and nutrients recycle.
• energy is limited in the biosphere, and nutrients are always available.
• nutrients flow in one direction, and energy recycles.
• energy forms chemical compounds, and nutrients are lost as heat.
There's difference between the movements of energy and the nutrients through living systems due to the fact that energy flows in one direction, and nutrients recycle.
In order to maintain ecological balance, it should be noted that the energy flow in the ecosystem is vital. The producers produces the food through photosynthesis.
Then, energy is passed from one trophic level to another trophic level. Energy flows in only one direction which brings about the difference in the movements of energy and nutrients through living systems
