Answer:
The correct answer is: Species with limited resources usually exhibit a <em>logistic</em><em> </em>growth curve
Explanation:
In ecology, logistic growth refers to the phenomenon where the growth rate of a population decreases as the population reaches its carrying capacity (the number individuals that an environment can support without facing degradation). To put it simply, when a certain species has limited resources available to them, as they reach their carrying capacity, the population of that species will decrease due to death caused by lack of resources for consumption. The attachment shows what logistic growth looks like when plotted on a graph.
Answer:
Natural selection
Explanation:
Microevolution refers to changes produced at a lower level than species. In genetics, microevolution is the change in the allelic frequency perceptible in a few generations. Most of these naturally produced changes by mutation, natural selection, genetic flux, genetic drift.
After the drought on Daphne Major, many of the plants producing small-sized seeds decreased their reproductive rate drastically. Consequently, there were almost no seeds available for the medium ground finch to feed. The population of this species also decreased to only a hundred birds over two years. Weather conditions and food availability influenced the survival of the animals.
With time, the finched population increased again, but now, the average size of the beaks was larger. The trait modification was related to the availability of only larger seeds with thick husks.
Eating large seeds with medium or small-sized beaks was impossible, so Finches needed to adapt, developing larger beaks to crack open the husks and eat the contents of the seeds.
<u>Natural selection was responsible for the rapid change in the finches´ population beaks size after the drought. </u>The evolutive force modifies the allelic frequencies, increasing the frequency of genetic variants that expressed the larger beak size and declining the frequency of the alleles that expressed smaller beak size.
