COMPLETE QUESTION: Which is a characteristic of exponential population growth? Options:
(a) Growth rate is inversely proportional to population size.
(b) Initial population growth is rapid.
(c) Resources are consumed exponentially during all phases.
(d) The lag phase follows rapid growth.
ANSWER: OPTIONS: B and D
EXPLANATION:
In Exponential growth strategy, the growth rate increases as the population size increases. This results as increase in natality and low mortality rate, hence it skyrocket the population beyond the carrying capacity.
Secondly, the initial population growth is rapid because of increased natality and resources to satisfy the population are still even.
Thirdly, the resources to satisfy the total population decline over time, when the population size is more than the carrying capacity, and this can results into competition.
Lastly, the lag phase is the first phase of exponential growth when there is rapid growth due to increased birth rate and evenly distributed resources below the carrying capacity.
