Best Answer

Because invertebrates are animals without backbones, they differ from vertebrates.

They are to digest when eaten.

Invertebrates are important because they start the food chain e.g amphopods eat algae under the arctic ice cap and they get eaten by a vertebrate that gets eaten by a larger vertebrate.... and so on. So invertebrates basically power most food chains.
