What would happen if the first link was removed from the food chain?

Answer 1

All herbivorous animals (animals that eat only plants) would die, because they would have nothing to eat. Bigger animals that eat the herbivorous animals would die, because there would be no small animals to eat. Humans would not have any meat because all the big and small animals are now dead. We would all have to be vegetarians, and because there are no longer any plants (including vegetables and fruit) we would also starve.

But plants produce oxygen, so we would all choke to death before we could starve.

Answer 2

The shark is at the top of the food chain, so the number of fish that it eats may increase. The number of sick and injured fish would also increase since sharks often 'clean up' the populations, sickness could become more widespread in the oceans. Most likely another type of animal(s) would fill the role of a shark.

Answer 3

If the first link in a food chain were removed, it would disrupt the entire chain, leading to a decrease in population of the organisms at each successive trophic level. This could result in imbalances in the ecosystem, affecting the overall functioning and stability of the food web.

Answer 4

If one link is removed, the link which ate the removed one will probably look for a new specie to eat, or become a endangered animal, and then die of starvation.
