The light-dark-bottle method is a technique used in aquatic ecology to measure the rate of photosynthesis and respiration in water samples. It involves placing water samples in two different types of bottles: one that is transparent (light bottle) to allow light penetration and another that is opaque (dark bottle) to block light. The light bottle measures the net photosynthesis, while the dark bottle measures respiration. The difference in oxygen levels between the two bottles indicates the productivity and metabolic activity of the aquatic ecosystem.
