Birthnate of endangered species the birthrate of an endan- gered species of whales in year t is f(t) whales/year. this species of whales is dying at the rate of g(t) whales/year in year t. what does the function f(t) = f(t) - g(t) represent?

The birth rate of the endangered species of whale is given by the function f(t), where t is time in years. The death rate of the species of whale is given by the function g(t). The surviving numbers of the endangered species of the whale can be figured out by looking at the difference between the birth rate and the death rate. This growth rate is given by the function, y(t) = f(t) - g(t). The recovery of an endangered species can be assessed by the slope of the growth rate function. Negative slope indicates higher deaths and positive slope indicates more births.

explanation:

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
