    Solution:

    The neural organisation is very simple in lower invertebrates. For example, in Hydra (Cnidaria) it is composed of a network of neurons. The neural system is better organised in insects  (Arthropoda), where a brain is present along with a number of ganglia and neural tissues. Star fishes of Echinodermata have a nerve ring and radial nerves. Members of Porifera are devoid of neurons.
