Reduced ability of colonial animals to find or obtain food: d. Ch anges in gene frequency due to natural selection; e. Dispersal of young animals who cannot obtain a territory I 1. (4 points) Which of the following is true of density-independent population growth (pick 1) a. Per capita growth rate is highest at intermediate population sizes; b. Population size always increases; c. Population age structure is constant; d. Population size doesn't reach an equilibrium (other than 0); e. Population growth rate is constant; 12. (5 points) Which of the following is true of the logistic equation (pick 2) a. Per capita growth rate is highest at intermediate population sizes b. Population growth rate is highest at intermediate population sizes; c. Per capita growth rate is constant d. Per capita growth rate is highest at high population sizes e. Population growth rate is highest at low population sizes; f. Per capita growth rate is highest at low population sizes;Explanation / Answer
10.A) and C)
Allee effect focusses on the correlation between the population densities and the overall fitness of the individuals .
It is affected by the following mechanisms-
11.d) In the density dependent population , all the characterstics , like age structure and growth always fluctuates, it never gets to an equilibrium.
12.e) Logistic growth is - when the growth of is highest when the populationis low.
