Which of the following is an example of a microclimate affecting an organism's fitness?
Select one or more:
a. A rat carcass lying in a sunny location, slowing the growth of fungus on it.
b. Seasonal rainfalls increasing in frequency, allowing a tree to produce more seeds.
X
c. Average temperatures increasing across a forest, leading to a reduction in prey for wolves to feed on.
X
d. A local wind mixing oxygen into the surface of a lake, increasing diatom photosynthesis rates
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.
Which of the following is not true of a population of largepredators in a small reserve?a. The species may disappear from the reserve.b. The species will probably undergo a populationexplosion.c. The species will probably lose genetic diversity.d. The species may overeat its prey, causing a reduction inprey population.
