One year, heavy rain makes lake raymond very deep. the next year, however...
Option D, There will be less animal life the second year.
Lake is an ecosystem which predominantly consist of plant and animal species which are able to survive and grow in water.
During the first year heavy rain had increased the depth of Raymond lake and this caused more plant and animal species to grow/regrow and survive.
While the same species faces problem when the water level in the Raymond lake decreases as there is no rain second year. The most badly affected are the species that lives at greater depth of the lake which was least exposed to sunlight or any other external environmental factor. But due to receding water level, even the species living at greater depths get affected.
Thus, option D is the most appropriate answer
not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
