• Plants require light for photosynthesis but not respiration

• Plants require light for cellular respiration

• Plants require light for both light and cellular respiration

• Plants do not react differently at night compared to the day

Which of the following describes why oxygen is a good indicator for photosynthesis in the graph

• Oxygen is an input of photosynthesis

• Oxygen is an output of photosynthesis

• Oxygen is both an input and and output of photosynthesis

• Oxygen cannot be used to measure photosynthesis rates

Which of the following best explain why adding nutrients to water can lead to fish suffocating?

• Living algae produce O2 during photosynthesis

• When algae die, decomposers eat them and consume O2

• Living algae consume more CO2 than O2

• Living algae cannot be used as food for other animals

Answer explanation

Decomposers perform cellular respiration.

Cellular respiration uses oxygen when animals eat.

The more plants alive the more plants die.

The more plants die, the more decomposers there will be to use up all of the oxygen.
