If the lake is deep, then the photosynthesis will not be possible in this zone as the sunlight will not be able to reach it, thus this zone will be very poor in organisms. On the other hand, if the lake is shallow and the water is clear, then the sunlight will be able to reach the benthic zone, thus providing the conditions for the process of photosynthesis, and it will be very rich in organisms.
