Diatoms are so small that oxygen just passes through their bodies.

Red algae belongs to the taxonomic domain of Eukarya, members of which are characterised by having cells with nuclei. Eukarya covers all organisms in the Kingdom Protista, as well as the Kingdoms Plantae, Fungi and Animalia.

No. Only animals need sun. Animals have a process called hydrosynthesis, which is using the sun's luminosity to digest water.

to wetlands non e to deserts it adapts with its sharp calws which helkps kill it eemines

Hell no

Algae is found every where, even in the desert. If you take a handful of desert dirt and let it sit in some water in light, algae will start to grow. Thankfully it is very resilient, it produces most of the oceans oxygen and is the bottom link in the food chain for aquatic life. it is found in places which are damp and exposed to sunlight. it can also grow on walls. eg. under a tap

Although cyanobacteria do not have chloroplasts, they do have thylakoid membrane, where photosynthesis occur.

i dont no it may be if u get the answer tell us

Algae are unicellular plants- and so they make their own food by photosynthesis. i won't highlight all the biochemistry in detail, but the following equation sums up the reaction:

6H2O + 6CO2 (+ Sunlight) = 6O2 + C6H12O6

The equation above states that water and carbon dioxide are converted into glucose( the plant's food) and oxygen as a waste product- using light energy to drive the reaction.

The natural predator are a lot of other animals that I don't know!=P =) =}! LOL!

In the Proterozoic, 2.5 billion years ago, but these were not advanced modern algea, but primitive Cyanobacteria. Cyanobacteria still exist today, but in their heyday, they were the dominant form of life on Earth, and may be been the first to form colonies. Over about 1 billion years, they produced the bulk of the free oxygen in our atmosphere, poisoning they own environment and setting the stage for modern plants and animals to take over.

We owe them our lives, for without them, all oxygen would be bound up in the rocks as it is on Mars.

A very good question. Algae is actually the foundation of our entire food

chain and therefore a serious reason people need to be concerned about

what is going on with our oceans. Algae is the simplest form of plant life

on this planet, which derives nourishment directly from the sun, and the

absorbtion of substances in the sea. It is actually beautiful to be in a big

patch of it on a moonlit night, out in the middle of the ocean, because it

glows in the dark. The point is we all basicly derive our energy from the

sun so algae is what converts it to something we can eat. Of course you

can eat the stuff in that form if you want to but it doesn't taste anything

as good as a nice steak and lobster dinner.

Only some healthfood supplements. Green algae (or any type of algae, for that matter) is not commonly added to foodstuffs and does not occur naturally in many foodstuffs either. Sushi or sashimi does not contain algae - it contains nori seaweed.

No, algae are photosynthetic, they don't 'eat' anything so they can't be a herbivore, carnivore or an omnivore, they just absorb nutrients from the water.

Photosynthetic microorganisms that live in water.

the symbiosis relationship between aquatic turtles is commensalism because the algae benefits by living on the turtle but the turtle is not affected by the algae at all.
