Final answer:
Serval cats utilize auditory and visual receptors, spiders use mechanoreceptors, chameleons have specialized visual receptors including the ability to see polarized light, and male silkworm moths possess chemoreceptors for detecting female pheromones.
Step-by-step explanation:
The various types of receptors that organisms use to perceive stimuli are highly specialized and adapted to their environment and behaviors. In the case of serval cats, they might utilize auditory receptors sensitive to the rustling of prey in the underbrush, as well as visual receptors attuned to movement. Spiders generally rely on mechanoreceptors on their legs to detect vibrations on their web, signaling the presence of prey. Chameleons have very distinct visual receptors, allowing them to perceive small changes in their environment necessary to hunt insects; they can also detect polarized light. The male silkworm moth is known for its chemoreceptors that are sensitive to the pheromones released by female moths over long distances. These chemoreceptors are an example of receptors that respond to chemical stimuli such as ions and macromolecules that diffuse across cell membranes.
