What is on top of the food web?

The top of the food web is occupied by apex predators. These are animals that have no natural predators in their ecosystem.

Here are some examples of apex predators:

* Land: Lions, tigers, wolves, polar bears, great white sharks

* Sea: Orcas, sharks, tuna, marlin

* Air: Hawks, eagles, owls

It's important to note that "top" can be a bit relative depending on the ecosystem and the scale you're looking at. For example, a wolf may be an apex predator in its forest environment, but it's prey for a larger predator like a bear.

The concept of apex predators is crucial for maintaining a healthy ecosystem. They help to regulate populations of other species, keeping the balance within the food web.
