Question

The movement of energy and nutrients through living systems differs in that way
A. Energy recycles while nutrients flow in two directions
B. Nutrients recycle while energy flows in one direction
C. Nutrients are lost as heat while energy forms chemical compounds.
D. Nutrients are constantly available while energy is limited
E. Nutrients are lost as heat while energy is limited.

Answer 1

Hint:- In ecology, energy flow also called caloric flow, refers to the flow of energy through the food chain, And the focus of the study is ecological energetics. A general energy flow scenario follows solar energy. Solar energy is fixed by photoautotrophs, called primary producers like green plants.

Complete step-by-step solution:-
- The energy flow in the ecosystem is important to maintain ecological balance. The producers synthesise food by the process of photosynthesis. A part the energy stored within the plants, the meaning energy is utilised by the plants in their growth and development.
- Energy is passed from one trophic level to the next trophic level.Hence energy flows in one direction through successive trophic levels in a food chain. Nutrients are produced from the matter. The matter may be organic or inorganic. The organic and inorganic matter is produced, exchanged and mood within the ecosystem and this is called cycling. Hence nutrients are recycled.
- The movement of energy and nutrients through living systems are different because energy flows in only one direction. Nutrients flow in one direction and energy recycles
The energy flow in the ecosystem is important to maintain an ecological balance. Energy forms chemical compounds, and nutrients are lost as heat.
So from above discussion we can conclude that correct answer is option B Nutrients recycle while energy flows in one direction.

Note:- Energy flow refers to the flow of energy through food chains. Energy is passed from one trophic level to the next trophic level.Hence energy flows in one direction through successive trophic levels in a food chain. Nutrients are produced from the matter. The matter may be organic or inorganic.
