Explain in short plz. Asap. Thanks   Imagine a population of cacti living on an imaginary island called Plantopia. These cacti evolved to stop producing spines because there are no herbivores on Plantopia. Every year, a few cactus seeds are washed onto the shores of Plantopia from the mainland. There are many large herbivores on the mainland. (Tip: Try drawing the scenario to help you visualize it.) Name three mechanisms of evolutionary change ( 3 of mutation, natural selection, genetic drift, and gene flow.) that may be acting on alleles for spine production on Plantopia. For each mechanism, explain what effect it may have on spine production, and whether this change is adaptive or non-adaptive

Ecological Interactions

The study of the ecological interactions between living beings and their physical environment, including humans, is ecology. It aims to understand the crucial links between plants and animals and the world around them. Ecology also gives knowledge on the advantages of ecosystems and how we may use Earth resources to ensure that future generations have a healthy environment.
