The phytoplankton transforms light energy into 100,000 kcal (by photosynthesis of course). How much energy would you expect to be available in the elephant seal's food if the
elephant seal eats the squid, which eats krill, which eats phytoplankton?
O 100 kcal
100,000 kcal
10,000 kcal

A niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.

O The predatory animals that eat the shellfish will move on to find food sources elsewhere. O The predatory animals will most likely die due to a lack of food sources necessary to sustain life. There will be no change to the predatory animals due to a decrease in the shelled marine life. The predatory animals will adapt to the change in food sources and eat alternative prey that is available. O The predatory animals will produce more offspring that will be able to survive in the changing ecosystem.arrow_forward
