User: Abiotic factors

Weegy: Light Light is an essential factor for photosynthesis. It may also be a habitat factor. Fishes and invertebrates shun sunny spots within the stream in order to be less visible to predators. [ Most of the life forms are found in places where higher density of light is present. In areas of lower light density, very few species such as amphipods and springtails are found. Current Current is a factor that interacts with many abiotic and biotic effects. Many organisms occupy a certain range of water velocities while they get stressed at water with higher velocities. Current performs an essential function of transferring food to waiting organisms. It also transfers oxygen to organisms, which aids with their respiration. The same flow carries nutrients and carbon dioxide to plants. Read more: Abiotic Factors in an Aquatic Ecosystem | eHow.com ]
