Total questions: 5
Worksheet time: 3mins
What is the importance of photosynthesis in the ecosystem?
It depletes oxygen, reduces food supply, and disrupts the carbon cycle.
It has no impact on the ecosystem.
It only benefits a few select organisms.
It produces oxygen, provides food for organisms, and helps regulate the carbon cycle.
Explain how photosynthesis helps in the production of oxygen.
Photosynthesis helps in the production of oxygen by converting carbon dioxide and water into glucose and oxygen using sunlight.
Photosynthesis helps in the production of oxygen by converting methane and oxygen into carbon dioxide and water using sunlight.
Photosynthesis helps in the production of oxygen by converting nitrogen and hydrogen into glucose and oxygen using sunlight.
Photosynthesis helps in the production of oxygen by converting sulfur dioxide and nitrogen into glucose and oxygen using sunlight.
How does photosynthesis contribute to the food chain?
It is the first step in the food chain, producing food for primary consumers.
It actually depletes the food supply for other organisms
It has no impact on the food chain
It only benefits the plants themselves
Discuss the role of photosynthesis in the carbon cycle.
Photosynthesis helps in converting carbon dioxide into organic compounds and regulates the amount of carbon dioxide in the atmosphere.
Photosynthesis converts carbon dioxide into nitrogen
Photosynthesis has no role in the carbon cycle
Photosynthesis releases carbon dioxide into the atmosphere
Why is photosynthesis considered as the most important biochemical process on Earth?
It is the primary source of oxygen production and food supply for all living organisms on Earth.
It only benefits a few select species
It has no impact on the environment
It helps in the production of carbon dioxide
