If you are referring to the Pleco, then no. They are a fish and fish use gills to extract oxygen from the water. In poor water conditions you may notice fish staying at the top of the water almost like the are gasping for air, however most species of fish can not take air directly from the...well....air.
No, because plants are not made up of algae
Smoke eaters are extremely efficient air cleaning systems. They clean particles up to three microns which allows people to breathe extremely clean air.
organisms that make up food chain are, the ocean mammals and also the land mammals
Most of them will eat other greens like lettuce and zucchini as well as algae. It sometimes helps to blanch the vegies to soften them up for the fish to eat. Good pet shops should stock pellets designed for algae eaters.
The only algae eaters that are safe with goldfish are bristlenose plecos. Weather (dojo) loaches can also be placed with goldfish, but they are not comparable to a pleco for cleaning algae (though they do clean some).
You should really get a algae eater. Some of the alge killers are harmful to the fish. it really depends on what type of algae. if its green water algae then use and algicide which you can purchase from aquariums. if it's filament algae then get some snail or algae eating fish. the quickest solution is to scrap the algae off yourself.
No they do not
Fish bottom suckers are species of fish that have specialized mouths for sucking up algae and small organisms from the bottom of bodies of water. They often have specialized adaptations such as suction cup mouths or underbellies that help them cling to surfaces and feed. These fish play an important role in maintaining the health of aquatic ecosystems by consuming algae and detritus.
Algae primarily use passive diffusion to take up chlorine from pond water. Chlorine molecules move from an area of higher concentration (pond water) to an area of lower concentration (inside the algae cells) through the cell membranes. This process occurs naturally as algae come into contact with the chlorine in the water.
to breath
yes
No . It does not.
