Digestion takes place within the cell (intracellular digestion)- Protozoans, Sponges. Some Invertebrate species can produce their own food by growing bacteria and cells inside their bodies. Protozoans, Sponges, Coelenterates and many worms have a direct diffusion of gases. Some species of invertebrates, such as grasshoppers, crickets or cicadas, produce songs to attract females and reproduce. Some of them reproduce through asexual mode and some reproduce through both the modes. Vertebrates are members of the subphylum Vertebrata, the clade Craniata, and the phylum Chordata. (2 marks).

Annelids exchange gases through moist skin. (1 mark). Most multicellular organisms have symmetrical body designs, whether they are radial, bilateral, or spherical. Both fossil and genomic evidence suggests that vertebrates arose during the Cambrian explosion.The Cambrian explosion was the relatively brief span of time during the Cambrian period during which many animal groups appeared and rapidly diversified. Most of the vertebrates have an advanced nervous system that makes them smarter. Invertebrates lack a backbone and have soft bodies due to the lack of an internal skeleton (endoskeleton) to provide support. This hypothesis is further supported by the fossil of a 530 million-year-old organism with a brain and eyes like a vertebrate, but without the skull found in a craniate. Invertebrates animals include a diverse group including sea stars, earthworms, jellyfish, sea urchins, sponges, lobsters, crabs, insects, spiders, snails, clams, and squids.
