In an aquatic ecosystem, chemical fertilizers can lead to increased nutrient levels, particularly nitrogen and phosphorus, which in turn can promote the growth of primary producers such as diatoms and algae.
When fertilizers enter the lake, they can stimulate algal blooms due to the rapid growth of these producers. Initially, these diatoms and algae will absorb the chemical fertilizers, causing them to have the highest concentration of the chemicals.
As you move up the food chain, the concentration of the chemical may change due to biological magnification. However, since the question is specifically about the highest concentration of the chemical fertilizer immediately after spraying, the organisms that would contain the highest concentration are diatoms and algae.
**Answer: diatoms and algae**
