What are some examples of primary productivity?
Primary production occurs in both terrestrial and aquatic plants as well as in algae, and chemoautotrophs.
On land, plants act as primary producers, with examples including lichen, trees, grasses, ferns, mosses, and so forth.
Aquatic primary producers include kelp and water lilies and other plants like you see below.
Deep sea vents like the one below are home to chemoautotrophs.
