Which of the following accurately describes a trophic cascade?
a. Sunflower stars, as a primary predator within Northern California bull kelp forests, have an indirect positive impact on the sea
urchin's main prey, the bull kelp.
b. Sunflower stars, as a primary predator within Northern California bull kelp forests, have an direct positive impact on the sea
urchin's main prey, the bull kelp.
c. Sunflower stars prey directly on kelp and keep kelp populations in check.
d. The presence of Pisaster sea stars benefits Mytilus mussels, a primary producer.

A. When a regulating factor exists that keeps the population at equilibrium
B. When feedback mechanisms kick in and population growth declines below carrying capacity
C. When equilibirum is reached
D. When density-dependent factors come into play and population levels start to decline ❌

- A biologist determines the growth rate of a population of 198 frogs in a marsh near Beaverhill Lake, Alberta, to evaluate the quality of the environment. The researcher finds that, in one year, 34 were born, 86 died, 12 migrated into the marsh, and there was no emigration. a. frogs are considered an indicator species for the quality of the environment.
