Exploring Levels of Organization in Ecology

The video introduces ecology as the study of interactions between organisms and their environments, both living and non-living. It explains the levels of biological organization from atoms to organisms and then transitions to ecological levels, including populations, communities, ecosystems, and the biosphere. The video provides a detailed look at each level and introduces the BECPO acronym to help remember the hierarchy.

What is ecology primarily concerned with?

• The study of weather patterns

• Genetic variations among species

• Interactions between organisms and their environments

• The classification of different species
