Question

What are the advantages of invertebrates?

Answer 1

Answer:

Invertebrates probably have the advantage of being able to fit or squeeze into smaller spaces (they lack a rigid backbone). A backbone would probably contribute a significant amount of mass and require a large amount of energy to maintain; therefore, invertebrates probably require substantially less energy to function.

Answer 2

Answer:

Invertebrates are hugely diverse, constituting the vast majority of species on the Earth and with a large proportion yet to be identified. They are crucial components of food webs and fulfil many ecosystems services, such as pollination, decomposition and nutrient release.
