The Ecology of Populations
Biology · 50 practice questions
Population density and overcrowding; adaptation for survival (intra- and inter-specific competition, competition and succession); factors affecting population size (biotic and abiotic); ecological succession (primary and secondary).
- Determine the reasons for and consequences of rapid population change/overcrowding.
- Compute population density.
- Relate population increase, disease and resource shortage to competition, and competition to succession.
- Deduce the effects of biotic and abiotic factors on population size.
- Trace the sequence of succession to the climax stage.
Try a few questions
- Practice question 1
A climax community, the end result of ecological succession, specifically describes a community that is
- A.relatively stable and in equilibrium with its environment
- B.a factor entirely unrelated to stability or equilibrium of any kind
- C.constantly changing in composition from one year to the very next
- D.always composed exclusively of pioneer species, with no later arrivals
Show the answer
A. relatively stable and in equilibrium with its environment
A climax community, the end result of succession, specifically describes a relatively stable community in equilibrium with its environment.
- Practice question 2
Overpopulation, in ecology, specifically describes a situation in which a population's size
- A.exceeds the carrying capacity of its environment
- B.remains well below the carrying capacity of its environment at all times
- C.is reduced permanently to zero as a direct result of overcrowding
- D.a factor entirely unrelated to exceeding the carrying capacity of an environment
Show the answer
A. exceeds the carrying capacity of its environment
Overpopulation, in ecology, specifically describes a situation in which a population's size exceeds its environment's carrying capacity.
- Practice question 3
Ecological succession, over a long period of time, specifically tends to lead toward the eventual establishment of a
- A.relatively stable climax community
- B.community composed exclusively of pioneer species indefinitely
- C.a factor entirely unrelated to the eventual establishment of a stable community
- D.population that becomes smaller and smaller until it disappears entirely
Show the answer
A. relatively stable climax community
Ecological succession, over time, specifically tends to lead toward the eventual establishment of a relatively stable climax community.
