Fats <span>are the most highly concentrated source of energy in the body. It is broken down in cellular respiration.

The answer would be A.
hope this helped :)
The amount of total energy at each trophic level decreases as it moves through, so 90% is lost at each level. This means that only 10 percent of the energy at any trophic level is transferred to the next level; and the rest is lost as heat.
In this case, if a plant ecosystem has 3000000 kilocalories (kcal) of energy, about 300000 kcal will be transferred to primary consumers (for example grass hoppers). If the red-tailed hawks are tertiary consumers, they will get 3000 kcal of energy.
This could be the different times you did the experiment
All of the above. Each cell is working and helping in different specialized ways in the body.
