Aquatic Ecosystems and Organisms

Mr. Wicks introduces a new approach to learning vocabulary by using a pre-recorded video. The video covers key vocabulary related to aquatic ecosystems, including wetlands, plankton, nekton, benthos, littoral and benthic zones, eutrophication, estuaries, salt marshes, mangrove swamps, barrier islands, and coral reefs. Each term is explained in detail, highlighting its importance and role in the ecosystem. Students are encouraged to fill out their vocab sheets and can take the quiz at any time before the due date. The video is available on the classroom YouTube channel for review.
