ive heard fluctuating co2 promotes algae... hows it relate to that?
Would it stress you out if you had say 800 calories per day, then suddenly say 3000? Then 800, then 500, then 4000?
Same sort of thing.
Plants largest enzyme by total mass is Rubisco(the planet's for that matter), the amount is strongly regulated by CO2 concentration.
If the CO2 is moving all over and dipping into the limiting ranges for part of the day etc, then it will cause growth problems.
Algae have very little issue since their carbon demand is 10-1000X less than plants. Algae spores seem to sense this change, and plants stop growing.
Then algae attacks and grows all over the plants. So the focus is more on the growth growth of plants, then algae are rarely ever an issue and then only minor at that.
I've been saying this last part for the last 20 years.
