I choose the question: "List the different trophic levels found in a food web."
In a food web, there are several different trophic levels, which basically tell you where an organism fits in the food chain. The first level is called the producers. These are usually plants that make their own food using sunlight. Then, there are the primary consumers, which are herbivores that eat the plants. After them, we have secondary consumers, which are usually carnivores that eat the primary consumers. Sometimes there are also tertiary consumers, which eat the secondary consumers. Finally, there are the decomposers, like fungi and bacteria, that break down dead plants and animals, returning nutrients to the soil. So, the levels go like this: producers, primary consumers, secondary consumers, tertiary consumers, and then decomposers at the end!
