Question

The energy pyramid below shows a possible

Answer 1

Energy transfer is not an efficient process.

Explanation:

There is less amount of energy in the top of the energy pyramid than at the bottom because energy transfer is not an efficient process. During the process of energy transferring, some amount is lost and some are converted to other forms of energy.

• The sun is the ultimate source of energy for all life in the solar system.
• When autotrophs takes this energy, they produce food from it.
• They use light energy from the sun to produce chemical energy in food.
• Even this conversion process waste precious amount of energy.
• As one goes up the pyramid, more energy is lost during the process of converting from one form to another.

Answer 2

Answer:

The correct answer is option A: "Energy is lost between each trophic level as heat".

Explanation:

The energy pyramid describes the amount of energy available at different trophic levels, where the producers have 1000 kilocalories of energy and the tertiary consumers have only 0.7 kilocalories. The energy lost between each trophic level is explained by the lost of energy as heat. When the organisms at a trophic level are consumed by the next trophic level, energy is lost in the form of metabolic heat. I attached the missing image.
