1-Look at the equations for photosynthesis and cellular respiration below

Photosynthesis: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O + 38ATP

1a- What products of photosynthesis are used by animals?
In this process they use carbon dioxide and light to make sugars and oxygen.


1b-What products of cellular respiration are used by plants?
cellular respiration is that the plant takes in glucose and oxygen, gives out carbon dioxide and water and releases energy.


2a-If you had seaweed living in an aquarium with water, and you added BTB indicator. What color would you expect to see? Why?



2b-What would this tell you about the level of CO2 ?



2c-How do these results show that seaweed is doing photosynthesis?




3a-If you had a fish living in an aquarium with water, and you added BTB indicator. What color would you expect to see? Why?



3b-what would this tell you about the level of CO2?
people's blood for normal or abnormal carbon dioxide, or CO2, levels to help diagnose certain medical conditions.

3c-How do these results show that the fish is doing cellular respiration?




4-Complete the chart below for photosynthesis and cellular respiration.
What 3 variables affect PS?
What 2 variables affect CR?






5a-If you had an aquatic plant and animal in the same aquarium, and added BTB to the water. What would happen to the level of CO2? (increase, decrease, stay the same) Explain.

Respuesta :

Glucose and oxygen which can be used by the animals while on the other hand, carbondioxide gas is used by the plant.

Products of photosynthesis are glucose and oxygen which can be used by the animals in the process of cellular respiration while on the other hand, carbondioxide gas is the product of cellular respiration which can be used by the plant for making their own food during the process of photosynthesis.

If we had seaweed living in an aquarium with water, and we added BTB indicator, it shows blue color because there is less amount of carbondioxide gas which is responsible for the formation of carbonic acid. The reason behind little amount of carbondioxide gas is the process of photosynthesis done by seaweed.

Lower concentration of carbondioxide provides us information that seaweed is doing photosynthesis. If we had a fish living in an aquarium with water, and we added BTB indicator, we expect yellow colour because carbondioxide gas is added to the water by the respiration process of the fish.
