Diversity in ecosystems has to do with a combination of keystone species, symbiosis, and adaptations. First of all, in my keystone species presentation about grizzly bears I said, “grizzly bears control the population of moose, elk, and other hoofed animals which allow other plants to grow.” If grizzly bears did not exist the population of those animals would increase. And that would lead to there being less plants in those areas which means there would be less animals that live in the trees like birds. Also, they help make more berry bushes so that there is more food. The ecosystem would change dramatically if there were no more grizzly bears. Next, in the Data Nugget about coral bleaching the algae living coral is what makes coral the different
