Exploring Levels of Biological Organization

The video explores the levels of organization in organisms, from subatomic particles to the biosphere. It explains how atoms form elements, which combine into molecules, leading to organelles and cells. Cells form tissues, which create organs and organ systems, culminating in individuals. The video also covers population dynamics, community interactions, ecosystems, biomes, and the biosphere, highlighting the complexity and interdependence of life.

What are the most stable subatomic particles?

• Tissues, organs, and systems

• Atoms, molecules, and cells

• Electrons, protons, and neutrons

• Elements, compounds, and mixtures

What defines an atom?

• A group of similar cells

• The smallest electrically neutral particle of an element

• A stable particle formed by ionic or covalent bonding

• A subcellular structure
