1.Carrying capacity a.determines the extent of intraspecific competition b.determines the extent of interspecific competition c.can be exceeded without extinction of the population d.a and b e.a, b and c 2. In sigmoidal or S-shaped growth represented by logistic growth, where does interspecific competition play the greatest role? in the lower part of the S-curve, when populations are low in the middle part of the S-curve, when populations are increasing in the upper part of the S-curve, when populations are high in all parts of the S-curve interspecific competition does not play a part in sigmoidal growth 3. Which organism is a biennial and completes its entire life cycle in two years? A dandelion b. A radish c. A grape vine d. A salmon 4. Which of the following is an aspect of a species that would not show evolutionary evidence of past interspecific competition with another species? Species behavior c. Species morphology Species niche d. None of the above 5. Character displacement is associated with Sympatric species Allopatric species Island biogeography Primary succession Secondary succession

Explanation / Answer

1. The answer is option 'c'. Carrying capacity is the maximum number of individuals that can be sustained by resources of a particular area. If the population exceeds this capacity, the amount of resources left will not be enough. This will result in reduction in the number of individuals but not complete extinction of the population.
