The video tutorial by Justin Diwan covers the study of organisms and populations within ecology. It explains the interaction among organisms and their environment, focusing on four levels of biological organization: organism, population, community, and biome. Key abiotic factors such as temperature, water, light, and soil are discussed, along with their impact on ecosystems. The video also explores biotic factors, homeostasis, and adaptations like migration and hibernation. Population dynamics, including growth models and species interactions like predation and mutualism, are explained to provide a comprehensive understanding of ecological principles.
