Does the population size increase or decrease at higher trophic levels in the pyramid of numbers of an ecosystem consisting of a tree insects (that are 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
