Question

As the sun shines on Earth, plants use its energy to complete the process of photosynthesis. Energy is transformed during the process into chemical energy in the form of sugars, such as carbohydrates. However, the energy available at top consumers is much less than that produced by autotrophs. Why is this so?


There are fewer top consumers than producers in a food web.

There are more producers than consumers in the food web.

Primary and secondary consumers compete for food.

Most of the energy is used for life's processes.

Answer 1

Answer:

The top of the food chain consumes the least amount of energy because producers that are eaten by the first consumers in a food chain only receive about 10% of the energy that the autotrophs have. As you go up the food chain, 90% of the energy that the prey contains is not consumed. This is why the top consumer receives the least amount of energy from autotrophs.

Explanation:

Answer 2

Energy is transformed during the process into chemical energy in the form of sugars, such as carbohydrates. However, the energy available at top consumers is much less than that produced by autotrophs. this is so because Most of the energy is used for life's processes in the food web.

How does the energy gets consumed in a food web?

• The energy pyramid depicts the movement of energy from one trophic level to the next in the food chain.
• Raymond Lindeman proposed this law, which is known as the 10% energy law.
• According to the 10% law, 90% of the captured energy is lost as heat in the previous level, leaving just 10% for the subsequent level.

• Because only around 10% of the energy is transferred on to the next trophic level, this is the case.
• The remaining energy leaves the food chain in a variety of ways:
• During respiration, it is released as heat energy. It's employed in life/biological processes like movement.

hence Most of the energy is used for life's processes.
