NOTE: The image you need to see in order to answer this question is attachedA developer owns the property encompassing the three habitats above. By law, one of the habitats must be left intact to satisfy the zoning laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer suggests that Site C should be saved. Which of the following choices best justifies this decision?Responses
A) Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future generations of animals. B) Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it. C) Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species. D) Site C has more unique species in it than either Site A or Site B

An ecologist is studying a population of mosquitos living in a nearby pond. The ecologist estimates the population size twice a day - once at sunrise and once at sunset - for 5 days during the summer when mosquitos are reproducing. Their data is shown. Based on the data, what is the estimated carrying capacity for the population and what factor may have led to a change in data at day three? a. The estimated carrying capacity is approximately 167 thousand. The population may have decreased during day three because of decreased pressure from a limiting factor such as reduction of predators eating the mosquitos. b. The estimated carrying capacity is approximately 188 thousand. The population may have decreased during day three because of decreased pressure from limiting factors, such as more food being available.c.
