AP Biology UNIT 8 Ecology 8.4 Effect of Density on Populations Video
Ever wondered how population density affects survival in ecosystems? In this video, we break down the effect of population density and how limited food, water, and living space can impact organisms. You'll learn how dense populations increase competition, spread disease faster, and change how species interact with their environment. We also explore how ecosystems like rainforests, savannas, deserts, and wetlands support different population sizes based on available resources and carrying capacit
