What are the animals that have no natural enemies in the food chain?

In farmland, there are many food chains, such as locusts eat rice, frogs eat locusts, snakes eat frogs, and eagles eat snakes is a food chain. Once there is a lack of one in this food chain, the food chain will change. So almost every kind of food chain has natural enemies, but some do not. What are the animals in the food chain that do not have natural enemies?

What are the animals that have no natural enemies in the food chain?

Animals without natural enemies in the food chain include great white sharks, tigers, polar bears, orcas, lions, Komodo dragons, Andean vultures, sperm whales and so on. These animals are so large and aggressive that few animals can attack them.

Second, what is the food chain?

The food chain is also called "nutrition chain". Refers to the chain relationship in which various organisms in an ecosystem are linked by food. For example, algae in ponds are food for water fleas, water fleas are food for fish, and fish are food for humans and water birds. As a result, algae, water fleas and fish in the pond form a food chain with people or waterbirds. According to the relationship between organisms and organisms, the food chain can be divided into predator food chain, carrion food chain (broken food chain), and parasitic food chain.

Predators such as grass → hare → snake → eagle. Cereal plant → insect → frog → snake. Big fish eat small fish, small fish eat shrimp rice, shrimp rice eat zooplankton, zooplankton eat green algae.

Carnivore (carrion food chain). A food chain based on bits and pieces of food. Such as leaf fragments and microalgae → shrimp (crab) → fish → fish birds that eat fish.

Parasitism is based on large animals, and small animals parasitize to large animals to form a food chain. Such as mammals → fleas → protozoa → bacteria → filtering viruses.

The biosphere is made up of the food chain and the food web. If one of them is broken, it will affect other organisms. First of all, the number of organisms that feed on them will be greatly reduced, or even extinct. Secondly, the number of organisms that feed on these organisms will also be greatly reduced, or even extinct, and then one after another, human beings will also be a member of the biosphere, and eventually human beings will be affected.
