freshwater algae
Lake's green film
Freshwater algae are photosynthetic organisms that grow in lakes, ponds, rivers, and streams.
They range from microscopic single-celled forms to visible filaments and mats.
Some produce oxygen and form the base of aquatic food chains; others bloom excessively when nutrients run high, turning water green and sometimes releasing toxins: The pond was choked with freshwater algae.
