It is more beneficial to eat lower on the food chain, for a few reasons.
1. Our food has not traveled from all over in order to get to our plate, meaning less exhaust fumes, less chemicals in our bodies.
2. The food lower on the food chain has been grown locally, and fully organic, without any additives or chemicals. The food you are eating has come straight from the farm.
There are a few other reasons, if you are still interested read the Omnivores Dilemma. Very good book, the whole book answers your question.
There's more at the top of the food chain because there's more animals and food lower down.
Biomass refers to the food available for the next trophic level in a food chain. There is a higher biomass on the lower levels of the food chain, hence eating on those levels would provide more food energy.
More food, more people, lower cost, more goods
Generally the lower in a food chain an organism is the more abundant it is.
Foods that are lower on the food chain are more abundant than those higher up. If people ate mostly vegetables there would be a lot more animals to eat in the world.

Typically, the food chain is like a pyramid more than a chain. The lower on the food chain an organism is, the more of them that there are, because the lower organisms are usually smaller so it takes more of them to feed the larger ones at the top. ie sardines eat plankton, tuna eat sardines, and sharks eat the tuna.....each one is bigger than the other so there are more plankton than tuna, and more tuna than sharks.
A food chain is more relative. A food pyramid is more empirical. The food pyramid is more useful in determining food groups and needs.
the difference is that a food chain is smaller then a food web because a food web is more animals then a food chain
its just a more complicated form of a food chain
b/c animals in which the birds are eating are being affected by the pesticides which kills them. If the animals at the lower part of the food chain start to grow extinct then there will be no more food for the animals at the top of the food chains which means they will more than likely die off or become extinct
Plants and insects belong to more than one food chain
