– Why can birds & other animals eat berries that are poisonous & potential fatal to humans?

In: Biology

Because they have different physiologies to us. For instance, they may produce different chemicals in their livers which breaks the poison down into chemicals which aren’t poisonous to them.

There are things which we can eat which kill other animals.

Think of yourself as a factory.

Factories are not interchangeable. You can’t just go to a textile processing factory, throw a ton of soybeans onto the conveyor belt and expect that you’ll get soybean oil out of them. If you try, it’s just going to gum up the works and screw everything up.

Now, animals are much closer to each other in makeup than soybean and textile factories. It’s more like we’re all cotton processing plants – but there are still significant differences. If you try to process dyes in a factory that isn’t equipped to handle it, you’ll still get a mess.

So it is with animals. We have some similarities, most animals can process what most other animals can to *some* extent, but there are still significant differences.

This is only case for some berries but , the poisonous part is usualy stone , which doesnt get ingested by birds but simply goes trough their digestive system unharmed
