This week we’re diving below the lakes, streams, and oceans to look at an interesting group of organisms that are incredibly important to aquatic ecosystems. They are usually too small to be seen, but some can be relatively large in size. They can be plants, animals or something else entirely. Get ready to go underwater because we’re talking about some of the tiniest organisms in the sea: plankton.
“Even though [plankton] are referred to as plants or animals, they’re more like protists which are microscopic organisms that aren’t plants or animals. They’re in their own category!”
