Lichens look like moss. but they’re actually two organisms—usually fungi and algae—that live together in a mutualistic relationship. the fungi provide a sheltered place for the algae to grow and reproduce. what do you think the algae offer that the fungi can’t do?

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
