So everybody had already answered the ecosystem answer so there was no need to say the same thing again. Plus professor Bently was already moving on. She was waiting her turn to add her two cents when a hufflepuff had to be reading the definition out of a text book. Hannah had zoned out and couldn't be sure how long she had been zoned out. She had no idea what anybody else had said. Was it really necessary to add that much info? At this rate they would never get to the practical part of the lesson.

She blinked a few times and raised her hand. "Professor, ecosystems are essential because they will help us take care of plants by knowing their habitats and their persoanl needs." See you could get the point across without reciting a novel.
