I agree!! Bacteria have exponential growth that is determined by the amount
nutrients available to continue growth and reproduction. A population will
level off and maintain a balance proportional to nutrient level. If foods
increases so will the population. What I find interesting is that we all
agree that higher plants will eventually out-compete algae for nutrients,
provided there isn't an excess of nutrients. Does this not work for plants
vs. microbes?
I am not saying that plants can wipe out a bacterial colony in our aquaria,
but isn't it reasonable to suspect that the plants are more efficient at
competition for food?
