Web2 dagen geleden · The task of measuring productivity has to consider many elements. In simple terms, the Harvard Business Review says: take the units of output, in other words the product, and divide that by the units of input, in other words things like capital, labour and materials. Again, though, it is usually a bit more complex than that. WebLight availability and productivity. Light is important in wetlands because it is necessary for plants (algae and macrophytes) to undertake photosynthesis. During photosynthesis, inorganic carbon (CO 2) is transformed into carbohydrates. Ambient sunlight available to aquatic plants is limited by 2 principal factors: turbidity of the water itself.
