-The amount of biomass decreases from the lowest trophic level to the highest. In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy.
-The organisms in the highest trophic level receives the lowest amount of energy. This is because only 10% of energy moves from one level of the food pyramid to the next. When heat comes from the sun. 90% of it is lost to the environment, 10% is consumed by the plants (primary producer). As a primary consumer ingests the plant, 90% of the original heat from the sun is lost to the environment and the primary consumer receives 10%. The secondary consumer receives 10% and 90% is lost, and so forth.

Explanation:
The flow of the river is dependent upon the position along the stream in terms of the gradient. Near the top of a high gradient, the flow will be less than that near the bottom. Likewise, the steeper the river's gradient, the faster the flow of water (due to the pull of water down the gradient by gravity).
