there would be less nutrients for the plant.
What would be the decrease in population a year if no children were born?
Without births, the population decrease would be the same as the number of deaths, which is generally between 57-58 million a year.
Does the population size increase or decrease at higher trophic levels in the pyramid of numbers of an ecosystem consisting of any herbivores and birds feeding on the insects?
Population sizes decrease at higher trophic levels. If they increased the insects population would decrease meaning there would be less food available for the birds so their population size would then decrease. Look at the relationships between predator and prey species for more information
What will happen to a population made up mostly of individuals that are past reproductrive age?
The population would decrease significantly, and perhaps die out. This is because the birth rate would be small and the death rate would be large. As the "old" individuals die, there will not be enough "babies" to replace them.
How would a decrease in natality change the population?
A decrease in the birth rate will cause a decrease in population over time.
