The fish and their pray would have nothing to feed on and die themselves.
we would die, too
The animals will died and move to to areas
Microscopic plants and animals. When they died, they sank to the bottom of the oceans, where they rotted, and under pressure, turned into oil.
they died
the food chain would be totally messed up other animals would be eating different animals making predation worse and causing the popluation to decrease. hope that helps Astred
All of the animals would die. Cuz the animal that ate the plankton would die then the next species would die.
They died.
If all the animals died off you could possibly just eat plants, except that at least some plants are dependent upon animals to reproduce (some seeds won't germinate unless they pass through the gut of an animal, and others need to be pollinated by animals). And anyway, if ALL the animals died, you'd be dead too, because human beings are animals.
They would die too, for various reasons, as plants have many impacts on the environment to make it habitable for other life, and of course they are food sources.
I would cry :'(
they would have died sadly
It would decompose
