Aphotic Zone
Most ocean food chains depend on phytoplankton as primary producers. Where in the ocean do phytoplankton live?
a. throughout all ocean waters, because phytoplankton can tolerate a wide range of temperature and light conditions
b. within about 200 meters of the ocean shoreline, because phytoplankton depend on nutrients that wash into the water from land
c. within about 200 meters of the ocean surface, because phytoplankton require light to survive
d. attached to shells along the ocean floor, because phytoplankton cannot float
c. within about 200 meters of the ocean surface, because phytoplankton require light to survive
Scientists have observed the exponential growth of lionfish in the Caribbean Sea. Which of these predictions about the future of the lionfish population is the most likely to occur?
a. The lionfish population will continue growing exponentially indefinitely.
b. A limiting factor will cause the growth of the lionfish population to slow down, forming a pattern of logistic growth.
c. A limiting factor will cause the lionfish population to decline rapidly, and eventually decrease to near zero.
d. The lionfish population will enter a cycle of increasing and decreasing numbers, typical of many predators and prey.
b. A limiting factor will cause the growth of the lionfish population to slow down, forming a pattern of logistic growth.
A rabbit population is affected by parasitism and disease, both of which are density-dependent limiting factors. Which statement describes the effects of parasitism and disease on the rabbits?
a. Parasites and disease weaken or kill a constant percentage of the rabbit population, regardless of its density.
b. As the density of the rabbit population increases, parasites and disease weaken or kill a greater percentage of rabbits.
c. As the density of the rabbit population increases, parasites and disease weaken or kill a lesser percentage of rabbits.
d. Parasites and disease weaken or kill mostly the youngest and oldest rabbits, and not the rabbits of average age.
b. As the density of the rabbit population increases, parasites and disease weaken or kill a greater percentage of rabbits.

Jorge is exploring the ocean. On which of these journeys is he MOST LIKELY to pass from the photic zone into the aphotic zone?
a. a boat trip from the shore to the middle of the ocean
b. a boat trip from the middle of the ocean to the shore
c. a submarine dive from the surface into deep ocean water
d. a walk from the intertidal zone into shallow ocean water
c. a submarine dive from the surface into deep ocean water
Juanita is studying the food web of the open ocean. Which step would be most useful for her to follow to identify the primary producers of the food web?
a. Look for floating plants, such as water lilies.
b. Look for tiny phytoplankton that float on the ocean surface.
c. Look for small animal plankton near the ocean surface
d. Look for plants or animals that live along the ocean floor
b. Look for tiny phytoplankton that float on the ocean surface.
How is the storm classified as a limiting factor?
a. The storm is a density-independent limiting factor, because population size and density do not alter the storm's effect.
b. The storm is a density-independent limiting factor, because its effect depends on the size and density of a population.
c. The storm is a density-dependent limiting factor, because its effect depends on the size and density of a population.
d. The storm is a density-dependent limiting factor, because its effect depends on the strengths of its wind and rainfall.
a. The storm is a density-independent limiting factor, because population size and density do not alter the storm's effect.

b. Many fishes die in a pond when oxygen levels decrease.
c. The populations of wolves and rabbits change in a cyclical pattern.
d. Small plants and animals return to the land after a forest fire.
d. Small plants and animals return to the land after a forest fire.
