Question

1. the graph below shows the growth curve of a population of mosquitoes

a population of mosquitoes
in central alberta
time
a. explain how weather affects the population of mosquitoes from june to september.
b. explain how weather affects the population of mosquitoes from september to november.
c. what might this growth curve look like in a tropical (warm, wet) ecosystem?

Explanation:

a. From June - September, warmer and wetter weather likely provides ideal breeding conditions, increasing mosquito - egg hatching rates and survival of larvae, thus boosting the population.
b. From September - November, as weather cools and becomes drier, it becomes less suitable for mosquitoes. Cold temperatures can slow their metabolism and reduce survival rates, leading to a decline in population.
c. In a tropical ecosystem, with consistent warm and wet conditions, the mosquito population might remain high throughout the year, resulting in a flatter and more sustained growth curve rather than the seasonal peak - decline pattern seen in Central Alberta.

Answer:

a. Warmer and wetter weather from June - September promotes breeding and survival, increasing population.
b. Cooling and drier weather from September - November reduces survival and breeding, decreasing population.
c. The growth curve might be flatter and more sustained due to consistent warm and wet conditions.
