Q4.25. In the r- vs. K-selection classification, which of the following best describes an r-selected species? Individuals grow larger, live longer, reproduce later, and invest more resources into each offspring.

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.
