Enable members of the phylum to survive and reproduce.Explanation: The body plans to evolve as it enables the members of the phylum to survive and reproduce. The changes in the body occurs with respect to the change in the environment. This change helps the organism to survive in a better way. These organisms reproduce and their population adapt the changes in the environment due to evolution.

Option A,C and E.Explanation:Nematodes are round worm that live in either marine, dressage or terrestrial habitats. They are also called segmented worm. They are characterised by long, thin, tube-like appearance that have neither distinct head or tail and the rest of the body is bilaterally symmetrical. Nematodes are mostly microscopic and some are parasitic that are found nealrt everywhere. They cause diseases in both plants and animals. Examples are ascaris, hookworm, pinworms e.t.c.Nematodes are multicellular and have digestive tracts.

Option B, C, and D. Explanation:Phylum cnidaria are group of animals in the animal kingdom that live in aquatic habitat mostly living in marine. They have specialized cells called cnidocytes of nematocysts organelles that help in stinging and capturing prey. Their bodies is consist of mesoglea found between to epithelium layers. They are radially symmetrical .They have two majory body forms, swimming Medusa and sessile polyps. Cnidarians are diploblastic animals. Cnidaria can reproduce sexually.

Option B,C, D and E.Explanation:Phylum cnidaria are group of animal species found mostly in aquatic habitats and most of they live in marine habitat. They have cnidocytes, specialized cells used for capturing prey which contain nematocysts organelles. They have mesoglea present between two layers of epithelium. They are radially symmetrical with tentacles surrounding their mouth. They have two body forms, the swimming Medusa and the sessile polyps.Nematocysts is stinging organelles found in cnidaria and other animals for stinging their prey.Sea anemone is a member if phylum echinodermata.

Option C and E are correct.Explanation:Phylum molluscs are invertebrates species. They are the second largest phylum in the animal kingdom .Most mollusc live in marine and others live in freshwater and terrestrial habitat. Molluscs are ceoomates and they have three universal structures which are the mantle (breathing and excretion),radula and nervous system. The molluscs include snail, oyster,clams, periwinkles,octopus, squid e.t.c.The larvae of molluscs are bilateral symmetrical while the adults are asymmetrical. Molluscs can produce shell, the presence of shell is an inclusion in the phylum.Molluscs have three body part, the head, visceral mass and muscular foot

Option E.Explanation:Phylum porifera are group of organisms that live in aquatic habitats both marine and freshwater. They are diploblastic I.e they have two germ layers. They are assymetrical . They have round or vase-like or sac- like shape. They are multicellular and have bodies full of pores. They lack tissues and organs. Sponges are members of the phylum porifera.

Option EExplanation:Most of all poriferans/ sponges are suspension or filter feeders. Suspension feeders are organisms that each food materials which are suspended in their environment ie sea water, while filter feeders filter their food source from water by drawing water containing bacteria and organic matter in through their ostia(pores). Substrate feeders at organism that live in or on their food source.Members of the poriferans do hava an ectoderm (epidermis) and an endoderm including a non-cellular late that is present in between the two layers. No, they do not belong to the phylum cnidaria but porifera. Cnidarians including hydra, sex anemones, jellyfish etc and these have features that different from that of the sponges e.g the presence of nematocysts in cnidariansSponges can reproduce both sexually and asexually. Sexually by releasing larva fertilized in the sponge into water where they float around for some days and then proceed to adhere to a solid surface and begin their growth into adults. Asexually by buddingThey are multicellular, lack tissues, are animals, lack organs and are asymmetrical. These are th distinguish features of poriferans

Options A, B, C, D at correctExplanation:Cnidarians are a branch of invertebrates characterised by by a radially symmetric body including a saclike internal cavity and nematocysts; stinging structures that aids in feeding. They are also known as coelentrates. They are diploblastic (2 body layer). They also reproduce asexually by various mean including budding. Example include sea anemones, hydra, corals, jellyfish etc
