a pollutant released on one continent is found concentrated in the tissues of organisms on another continent. Is this likely an air, land, or water pollutant? Explain

It is most likely an air and water pollutant.

Explanation:

The continents are separated with water and air. Therefore, if a pollutant is released from one continent, it could have transported to the other continent via water and air. Although the effect of air is less due to dispersing of air masses, it still have a chance to transport the pollutant at far distance. This phenomenon can also be related with the transboundary pollution where a pollutant travels to another place. For example, many persistent organic pollutants have beend detected in the bodies of polar bears living in arctic.
