    It's called differential reproduction. There are a lot more smaller fishes than there are predators to eat them. In general, biomass increases by a factor of ten for each step down the food chain.

    Yeah, that is how it has been going for a very long time and the oceans were thriving and healthy. It is only in our century that the oceans are dying for all the plastics humans have thrown out and the pollution that causes climate change. But as for the oceans and the fish hunting for each other that has worked. But many fish eat plankton which is mainly plants. Nature is amazing and even though humans are slowly destroying it, we can still enjoy the beauty of it all around us . https://www.jw.org/en/library/magazines/awake-no6-...

    It's simple. There are many more smaller fish and their reproduction cycle is much shorter. That also applies to rabbits.

    Not all the smallest prey get eaten by bigger fish. Those that avoid being eaten lay millions of eggs. This ensures that the species survive.
