Ecologists use survivorship curves to visualize how the number of individuals in a population drops off with time. by plotting the number of survivors per 1,000 individuals on a log scale versus time, three basic patterns emerge, seen here in the graph. most individuals in this population produce many thousands of offspring, most of whom die right away. relatively little effort or parental care is invested in each individual. once this initial period is over, survivorship is relatively constant.

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.
