Aim: Explaining how food is converted into energy in producers and consumers.
Objectives
- Identifying the raw materials and products in cellular respiration vs. photosynthesis
- Explaining how the raw materials in processes are recycled in the ecosystem
Review of Cellular Respiration
Cellular respiration is a chemical reaction that gives cells the energy they need to survive, producing ATP.
Photosynthesis
- Carbon dioxide + Water + Sunlight → Glucose + Oxygen
Cellular Respiration
- Glucose + Oxygen → Carbon dioxide + Water + ATP
Process
- Location (organelle)
- Purpose
- Reactants (Raw Materials)
- Products
- Energy Source
- Type of Organism(s) that use this process
Photosynthesis
- Chloroplast
- Convert light into food
- Carbon Dioxide, Water, and Light
- Oxygen and Glucose
- Light energy
- Plant
Cellular Respiration
- Mitochondria
- Give cells energy to survive
- Oxygen and Glucose
- Carbon Dioxide, Water, and ATP
- Chemical energy
- Plant and Animal
The comparison between photosynthesis and cellular respiration is crucial to understanding how energy is produced and utilized in living organisms. Both processes involve the conversion of energy in different forms as they take place within different organelles and use different raw materials and products.
By understanding the similarities and differences between these processes, we can comprehend how energy is exchanged and recycled in the ecosystem, allowing both producers and consumers to survive and thrive. Therefore, the study of photosynthesis and cellular respiration is essential for understanding the fundamental mechanisms of energy production in living organisms.
