2. A population of flowers was separated into two subpopulations when a new river cut through the plain in which they were growing. The number of interbreeding events per year for the two subpopulations of flowers is shown in this graph. Twenty-four years after they were separated, can you conclude that the two subpopulations of flowers have become new species? Justify your answer. Number of interbreeding events 120 100 80 60 40 20 0 6 12 18 Years after new waterway 24

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.
