Explain why it is more energy efficient (in terms of the amount of total NPP required) to eat a pound of tofu (bean curd) than a pound of hamburger.

Hello everyone and welcome to today's video. So wish of the following consumers will receive more energy in a food chain. Before we jump into this problem, I want to go over a few key aspects that we need in order to solve it. Let's begin by visualizing a food chain in a food chain. We have the primary producers at the bottom and these primary producers are going to hold 100% of all the energy created in the food chain. Then these energy is transferred to the primary consumers in the form of an attempt of the original amount of energy. This energy is then passed again and this energy is then passed again until it reaches the apex predator Which received the least amount of energy. So when it comes to a food chain, the primary consumers which feed directly on these primary producers are going to be receiving the highest amount of energy in the form of 10% of the whole energy of the food chain. So we need to identify among our answer choices, the organism that is going to feed directly into these primary producers or these plants. And if we look at our answer choices, the only vegetarian or the only organism that is going to fit directly in the on plants is going to be the grasshopper. If we create this as a food chain, we're going to see that the grasshopper is fed on by the rats, which is fed on by the snake. And this is in turn fed on by the eagle. So the eagle here will be our apex predator and will receive the least amount of energy. And our grasshopper would be our primary consumer, and it will be receiving the most amount of energy. That is the end of the video. And I really hope this helped you.
