Different populations in the same ecosystem can have different limiting factors. A scientist recorded the factors that limit the growth of some of the species in an oak forest. Her results are shown in the table below.
OAK FOREST ECOSYSTEM
Population Limiting Factor
songbirds nesting sites
squirrels acorns
oak trees water
wildflowers light
After the scientist made her observations, a disease struck the oak trees in this ecosystem, causing many of their leaves to drop. What population would most likely increase in size as a result of this change?
