Elephants have very large heads that necessitate the need for a short, thick neck. Their short, heavily muscled neck prevents them from lowering their head to the ground to graze on grass or drink water from a pond. Elephants have evolved long trunks to reach grass and water. Which kind of selection is responsible for elephants' long trunks? O Stabilizing O Diversifying Directional

Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.
