Question

a food chain shows the flow of energy from one organism to another. where did this energy come from in the first place? What will happen if the first source of energy will not be there?​

Answer 1

Answer:

Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... An example of energy flow in an ecosystem would begin with the autotrophs that take energy from the sun. Herbivores then feed on the autotrophs and change the energy from the plant into energy that they can use.

Explanation:

• Energy flows into an ecosystem as a result of the capture of solar energy by plants, and through a food chain and food web. ... In ecology, energy flow is the flow of energy through a food chain. Energy passes from trophic level to trophic level, and each time about 90% of the energy is lost.
• A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem.

Answer 2

Answer:

firstly it is impossible that first source of energy will not be there. secondly the first (producers) are autotroph (who can prepare their food themselves)and contain autotrophic nutrition . they get raw material from surrounding.

hope it helps
