WebPondweeds are an important part of lake ecosystems. The structure created by pondweed shoots and leaves creates habitat and shelter for a large number of aquatic insects and fish (Berg 1949, Hayes 1974). Pondweeds also play a central role in many aquatic food webs. Plant leaves, seeds, and roots are a food source for insects, snails, fish ...
WebMar 6, 2024 · Ultimately, the higher the light intensity the less time it takes for the indicator to turn purple. This is because light effects the rate of photosynthesis.
