Answer:

The lowest concentration is at the bottom. It is dilute, but widespread.

Explanation:

The concentration of a pollutant in a food chain always starts with the lowest concentration in the first level, whether plant or animal.

Each successive food chain level concentrates the pollutant more in the level species. The pollutant is now localized, but concentrated.
