Saltwater blooms (Red Tide)
An algal bloom that is caused because of an increase in nutrients in the water. They are dangerous when the toxins that the algae produce become concentrated in the bodies of organisms that consume the algae.
Heterotrophs which have cell walls, and use spores to reproduce. They are able to move at some point in their lives. The three types are slime molds, water molds, and downy mildews.
Freshwater Algal blooms
Also called eutrophication is when a layer of algae prevents sunlight from reaching plants and other algae beneath the surface. Those organisms die and sink to the bottom. Then decomposers increase in number and use up the oxygen in the water. Without oxygen, fish and other organisms in the water die.
Green, unicellular algae that are found mostly in fresh water. Unlike other algae, they have one animal-like characteristic—they can be heterotrophs under certain conditions.
The buildup over time of nutrients in freshwater lakes and ponds that leads to an increase in the growth of algae.
A "false foot" or temporary bulge of cytoplasm used for feeding and movement in some protozoans, such as the Amoeba.
Commonly known as seaweed or giant kelp, contains many colored pigments and air bladders.
Plantlike protists that can be unicellular or multicellular, are autotrophs and depending on their pigments, can be green, yellow, red, brown, orange, or even black.
Animal-like protists from the group of Sarcodines that live in either water or soil. They feed on bacteria and smaller protists with their pseudopods.
Ciliates that live mostly in fresh water. They feed on bacteria and smaller protists. They use cilia to move and feed.
Protozoans are unicellular, heterotrophs and can be classified into four groups, based on the way they move and live. Most are able to move from place to place to obtain food.
