2. Which organisms have the least amount of energy available? Explain why. square

The organisms that have the least amount of energy available are typically the organisms at the highest trophic level in a food chain or food web. This is because energy is lost at each trophic level as it is transferred from one level to the next.<br /><br />In a food chain, energy is transferred from producers (such as plants) to primary consumers (such as herbivores), to secondary consumers (such as carnivores), and so on. At each trophic level, only a small percentage of the energy (typically around 10%) is transferred to the next level, while the rest is lost as heat or used for metabolic processes. This means that the amount of energy available decreases as you move up the food chain.<br /><br />Therefore, the organisms at the highest trophic level, such as top predators, have the least amount of energy available to them. This is because they are at the top of the food chain and have the least amount of energy transferred from the lower trophic levels.
