Final answer:
Jacks have predatory adaptations such as camouflage to blend into their environment and enhanced senses like vision to locate prey, making them efficient hunters. Prey might evolve various defence mechanisms such as coloration or toxins in response.
Step-by-step explanation:
Predators and prey have adaptations to predation that evolve through natural selection to enhance survival and reproductive success. For example, predators such as jacks commonly have adaptations like camouflage, which enables them to blend into their environment to sneak up on or entrap their prey. Prey, on the other hand, may evolve camouflaged coloration, sharp spines, or toxins as defensive adaptations.
Other predatory adaptations include enhanced senses such as excellent vision or hearing, which aid in locating prey. Physical characteristics like a sharp, hooked beak or strong legs with clawed feet enable predators like lions to efficiently capture and subdue their prey. These traits are often prominent in species that are active hunters during the day or night.
