What is consumed in photosynthesis?
Water, air and light.
What is created in photosynthesis?

What is consumed in cellular respiration?
Glucose and oxygen.
What is created in cellular respiration?
Water, oxygen, and energy.
What performs photosynthesis?
Producers.
What performs cellular respiration?
Nearly all living things.
How do humans affect carbon and nitrogen cycles?
Pollution creates more carbon in the atmosphere and excess fertilizer disrupts aquatic ecosystems.
How does BTB work?
The more CO2, the yellower the solution will appear.
How do energy and carbon flow through a food chain?
They both are brought into producers via photosynthesis. When the producer is eaten the herbivore gets some of the energy and carbon and the consumer gets some of the herbivore’s carbon and energy when it eats. At each level energy is removed as heat and carbon is removed from cellular respiration.
