Organisms interact with one another in an ecological relationship called co-evolution. Bird, bee, bat and plants are related phyloger evolutionary influence of the two species affected the organism's interactions to the environment. Plants are always visited by some animals like bee, bird and bat. The flowers are very attractive to these animals as source of food he plants to survive. The pattern of evolution can be traced in co-evolution. The two species are closely related having the same ancestor which interac symbiotic relationship. Animals like bee, bird or bat visits their favorite flowers to say 'hello'. In response, the flower welcome them, provide food which the nteraction benefits both. Co-evolution is a process which involves two species of different ancestors. The two species respond to changes that exerted an e These two species are connected to one another through ecological interactions.
Anatomy and Physiology of Special Sensory Organs
Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neurons are trained to find out modifications in the external and internal conditions so that a person's body can react to that change. A stimulus is the first signal that is recognized by any sensory receptor of the body. Stimulus is an impulse generated when there is a change in the surroundings of a person. For example, a heated environment will alert the brain through the thermal sensory organs and generate a reflex accordingly.
Sensory Receptors
The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory receptors are an important part of the sensory system. These receptors are specialized epidermal cells that respond to external environmental stimuli. These receptors consist of structural and support cells that form the peripheral unit of the receptor and the neural dendrites which receive and detect the external stimuli.
