Populations can change in size when new members join in the population or when members leave the population. what factors might have caused the increase of deaths in 1 year? what factors might increase the births in year 4? make sure to add such terms as limiting factors, birth rate, carrying capacity, immigration, and emigration.

Please help me

Population of a species is affected by a several of factors such as food availability,water and shelter etc.

Explanation:

If these factors such as food availability, water and shelter etc are unavailable to the organism, the death of the species occurs but if these factors are available in sufficient amount, then increase occurs in the population of species. If the place has low carrying capacity and limiting factors which is necessary for species then the immigration and emigration of the specie occurs. Those areas having sufficient food, water and shelter, the birth rate of a specie increases and which leads to increase in population.

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.
