Anything which we eat to live is called food. Food contains energy. The food (or energy) can be transferred from one organism to the other through food chains. The starting point of a food chain is a category of organisms called producers. Producers are‚ in fact‚ plants.

It is the pathway for electrochemical nerve impulses‚ which pass along axons of the peripheral organs. A neuron is a cell in the nervous system which plays many critical tasks like receiving sensory signals from the external and internal environments. Moreover‚ neurons join together these sensory responses to produce and transmit motor responses as a result of changes in membrane permeability
