1) A scientist increases the amount of carbon dioxide available to a plant. The plants rate of photosynthesis increases at first, but then levels off. What else might the plant need to further increase its rate of photosynthesis?
2) How would the composition of earth's atmosphere change if green plants and other autographs disappeared? Explain why in terms of your knowledge of photosynthesis.
3. How would animal life be affected by this atmospher change? Explain why in terms of cellular respiration.
I dont have a book. & I cant find the answers anywhere.. Anything helps thanks.
