The Principles of Biology

The principles of biology are fundamental concepts that explain how living things function and interact. They include the idea that all life is made of cells, which are the basic units of life. Living organisms grow, reproduce, respond to their environment, and maintain balance (homeostasis). They evolve over time through natural selection. Energy flows through ecosystems, supporting growth and reproduction. These principles help us understand life’s diversity, adaptation, and the interconnectedness of all living things.
