The size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.
<h3>What do you mean by Adaptation?</h3>
Adaptation may be defined as the process of modifying one's characteristics to better suit a situation and survive more efficiently.
The size of the tube that produces nectar is just 27.9cm long, while the length of the proboscis of a moth is 30.5cm. It easily consumes the nectar and gets energy for survival as well as reproduction.
Therefore, the size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.

<span>1) Receptors are linked with sensory neurons that send any signals that the receptors pick up to the brain. If the signal requires some kind of response to maintain homeostasis, signals travel through motor neurons to effectors.</span>
<span>2) The organ that controls the regulation of body temperature is the hypothalamus while the process that allows us to maintain our core temperature is referred as thermoregulation.</span>
3) Controlling blood sugar levels with insulin is a negative feedback mechanism. Receptors in the body sense when blood sugar levels rise. To deal with that, the pancreas pumps insulin into the blood to lower it. Blood clotting is a positive feedback mechanism where platelets start to clump around an injury in a blood vessel and release chemicals that bring more platelets that end up doing the same thing to form a clot.
