How does oxygen production relate to the rate of photosynthesis half a sentence no extra details

Increased oxygen production typically indicates a higher rate of photosynthesis.

How do you think light intensity affects the rate of oxygen production? half a sentence no extra details

Higher light intensity generally increases the rate of oxygen production during photosynthesis.

How do you think temperature affects the rate of oxygen production? half a sentence no extra details

Temperature affects the rate of oxygen production by optimizing enzymatic activity, with moderate temperatures typically enhancing photosynthesis until extreme heat or cold inhibit it.
