Living things have a complex organized structure made of organic molecules, respond to environmental stimuli, and actively maintain their internal structure and environment. They acquire and use energy from their surroundings to grow, reproduce using DNA, and evolve over time as a whole.

3. • Living things acquire and use materials and
energy from their environment and convert
them into different forms.
