What is algae's most important contribution to humans?

Answer 1

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

Answer 2

If algae wasn't in the water there would be a major upset in the ocean's food chain; for example, less algae means less food for fish which means less fish for us.

Algae can be genetically engineered to produce the amount of hydrogen it normally produces to the third power, and this extra hydrogen can be used to power fuel cells in engines and for other needs too.

Algae can be used a fuel source, a food source/supplement, a stabilizing agent in food products, as fertilizer, and in some methods of pollution control.

Algae is currently used in many wastewater treatment facilities, reducing the need for more dangerous chemicals. Algae can be used to capture the runoff fertilizers that enter lakes and streams from nearby farms. Algae is used by some power plants to reduce carbon dioxide emissions. The carbon dioxide is pumped into a pond, or some kind of tank, on which the algae feed. Algae is commercially cultivated as a nutritional supplement.

Answer 3

Humans benefit from algae because without it we would not exist. Algae is responsible for 70 to 80 percent of oxygen in the world's atmosphere through the process of photosynthesis. Seaweed, a type of algae, is used as food in many products across the world. Algae is also a forerunner in the race for creating the next clean-burning, renewable fuel. Algae is also used to feed fish which humans then in turn eat the fish. Without it humans would not have any fish to eat. Lastly algae is a source of agar and carrageenan.

Answer 4

Algae form organic food molecules from carbon dioxide and water through the process of photosynthesis, in which they capture energy from sunlight. Similar to land plants, algae are at the base of the food chain, and the existence of nonphotosynthetic organisms is dependent upon the presence of photosynthetic organisms. Nearly three-fourths of Earth is covered by water, and since the so-called higher plants are virtually absent from the major water sources (e.g., the oceans), the existence of nearly all marine life---including whales, seals, fishes, turtles, shrimps, lobsters, clams, octopuses, starfish, and worms---ultimately depends upon ...

Answer 5

They produce much of Earth's oxygen through Photosynthesis!

Hope that helped :)

Answer 6

They are useful because the produce oxygen
