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. Determine whether the growth rate of this population in one year is a cause for concern. if so, what might the concerns be?arrow_forwardChoose the best answer If an age-structure diagram indicates that there are more people inthe prereproductive stage of life than in the reproductive stage, thenreplacement reproduction, over the long run, will result ina. zero population growth.b. an increase in population size.arrow_forwardExponential growth often occurs whena. a population nears carrying capacity.b. a population exceeds carrying capacity.c. organisms invade a new habitat.d. the birth rate exceeds the death rate for a singlegeneration.arrow_forward
- Which of the following would not be an example of density-deperident factors regulating population size? The number of possible territories for robins is limited; thus when population sizes are high, a lower proportion of individuals can produce offspring. A. O B. In conditions of overcrowding, some desert pupfish living in ponds will emigrate to other ponds if given the opportunity. C.Predation on mosquitofish is high, regardless of population size. D. In conditions of high density, mice are more susceptible to mortality from heat stress. E. In a habitat patch with a high density of muskrats, a disease spreads more rapidly and results in higher mortality.arrow_forwardThe maximum rate at which a population could increase under ideal conditions is known as its (a) total fertility rate (b) survivorship (c) intrinsic rate of increase (d) doubling time (e) age structurearrow_forwardCarrying capacity is defined as a species’ average population size in an environment. Which of the following resulted to exceeding carrying capacity in a particular environment? a. increasing birthrates, decreasing deathrates, increasing immigration and no emigration takes place b. increasing birthrates, decreasing deathrates, decreasing immigration and no emigration takes place c. increasing birthrates, decreasing deathrates, decreasing immigration and increasing emigration d. decreasing birthrates, increasing deathrates, increasing immigration and increasing emigrationarrow_forward
