I’ll choose the question: "What happens to the amount of energy as it moves up through the trophic levels in a food web?"
As energy moves up through the trophic levels in a food web, it decreases or gets less. This happens because when plants and animals use energy for functions like moving or growing, they lose some of it as heat. For example, when a plant (which is a producer) gets eaten by a herbivore (like a rabbit), the rabbit doesn’t get all the energy from the plant. It only gets a small part of it because a lot is used for the rabbit’s own energy needs. Then, if a carnivore (like a fox) eats the rabbit, the fox also gets even less energy from the rabbit. So, by the time you get to the top of the food web, there’s not much energy left compared to what started with the plants. That’s why there are usually more plants than herbivores, and more herbivores than carnivores!
