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.
More food, more people, lower cost, more goods
Generally the lower in a food chain an organism is the more abundant it is.
Eating lower on the food chain provides more food energy because energy is lost as it moves through each trophic level. When animals consume other animals, they are absorbing energy that has already been partially used by the prey. By consuming plants directly, less energy is lost, resulting in more food energy available for consumption.
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.
More food, more people, lower cost, more goods
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.
Eating organisms lower in the food chain, such as plants or primary consumers, offers several advantages. These organisms generally provide a more energy-efficient source of nutrition, as less energy is lost through metabolic processes compared to consuming higher trophic levels. Additionally, lower food chain organisms are often more abundant and easier to access, allowing for a more sustainable and reliable food source. This can lead to a reduced ecological footprint and lower impact on food webs.
A food chain is more relative. A food pyramid is more empirical. The food pyramid is more useful in determining food groups and needs.
Less energy and effort is required to produce them. This is not necessarily an advantage for you personally as opposed to for the community of humans as a whole, though it does mean they tend to cost less.
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
