A natural habitat is an ecological or environmental area where a specific species lives. It is the place in nature that particular species calls home. To help picture what this means, think of a zoo.
Quick Answer. A mixture of vinegar and borax will kill most algae growing on bricks and concrete. Homeowners do not need harsh chemicals to get rid of these pesky growths.
Toxic Blooms. Some algae produce toxic chemicals that pose a threat to fish, other aquatic organisms, wild and domestic animals, and humans. The toxins are released into the water when the algae die and decay. The most common and visible nuisance algae in fresh water, and the species that are often toxic, are the cyanobacteria. A cyanobacterial bloom will form on the surface and can accumulate downwind, forming a thick scum that sometimes resembles paint floating on the water.
