Cellular Respiration and Ecosystem Dynamics

Miss Katherine introduces lesson 2.2 on how carbon dioxide enters the air. Students need a pen, paper, and access to Amplify Online. The lesson covers how producers, consumers, and decomposers release carbon dioxide into abiotic matter. Key concepts include cellular respiration and the role of decomposers. Students are encouraged to analyze diagrams and think critically about the process of cellular respiration and its impact on ecosystems.

What materials are suggested for today's lesson?

• A calculator and ruler

• A pen or pencil and lined paper

• A textbook and highlighter

• A laptop and headphones
