1. Primary Producers:
Algae are the main Oxygen producers in aquatic areas. They are also useful in decreasing water pollution by realizing Oxygen. 10% of photosynthesis is occurred by the algae in total photosynthesis quantity. With these activity algae forms 1.6-15.5 x 10 to the power of 11 tones of carbonic material like food.
2. Algae as food:
Algae species are used as food in several countries in several forms. Algae species have proteins, vitamins (A, B, C and E), lipids, and minerals. Laminaria species is the important edible seaweed in Japan and the food item 'Kombu' is prepared from it. 'Aonori' from Monostroma; 'Asakusa Nori' from Porphyra are prepared in different countries. Porphyra has 35% protein, 45% carbohydrates, Vitamins B and C and Niacin. Nostoc is used as food material in South America.
3. Algae as fodder for cattle:
Rhodymenia palmate is used as food for sheeps in Narvey. Laminaria saccharina, Pelvitia, Ascophyllum, etc. species are used as food for cattles.
4. Algae as fertilizers:
Blue-green algae are treated as bio-fertilizers from olden days. Nostoc, Oscillatoria, Scytonema, Spirulina, etc. are used as fertilizers to rice fields. All these algae are fixed the atmosphere Nitrogen in to ground. Cultivation of Spirulina is gaining importance as feed for fish, poultry and cattle.
5. Algae in Pisi culture:
Sea algae are used as food for fishes. So they play an important role in Pisi culture. Some green-algae, Diatoms, some blue-green algae are used as food material to fishes. These are also making the water clean, by realizing Oxygen.
6. Algae in reclamation of alkaline or Usar soils:
Our country has more number of alkaline soils or sterile soils. Blue-green algae like Nostoc, Oscillatoria, Scytonema, Spirulina are modified the soils in to fertile soils. Because they fixed Nitrogen in to soil. Nearly they fixed 400 K.g. of Nitrogen per year. Soil erosion is also reduced by these algae.
7. Algea in industry:
Iodine industry is mainly depended upon algae. Algae belonging to Phaeophyceae, like Laminaria, Ecklonia, Eisenia, etc. are used in the industry to prepare Iodine in industries. Phyllophora is used to prepare Iodine in Russia.
8. Alginates:
Alginates are the salts of alginic acid found in the cell wall of phaeophyceae. Alginates are extracted from Fucus, Laminaria, Macrocystis and Ecklonia. Alginates are used in the preparation of flame-proof fibrics, plastics, paints, gauze material in surgical dressing, soups, ice creams etc.
9. Agar-Agar:
Agar-agar is a jelly like substance of great economic value. It is obtained from certain red algae like Gelidium, Graciliaria, and Gigartina. Agar is used as a culture medium for growing callus in tissue culture.

✌️✌️hey mate here is the answer...
⬇️⬇️⬇️⬇️⬇️⬇️⬇️
economic importance:
➡️photosynthesis:
• at least half of the total carbon dioxide fixation on earth is carried out by algae through photosynthesis.
•being photosynthetic they increase the level of dissolved oxygen in their immediate environment.
•it is essential for respiration of aquatic life.
➡️Primary producers :
•algae are primary producers of energy rich compounds.
•This form the basis of food cycles of all aquatic animals.
➡️food supplements:
•many species of porphyra, laminaria and sargassum are among the 70 species of marine algae used as food.
•Certain unicellular algae like chlorella and spiral inner are rich in protein and are used as food supplements even by space travellers.
➡️hydrocolloids :
•hydrocolloids are water holding substances. certain marine brown and red algae produce large amount of hydrocolloids which are used commercially.
•algin and carrageen are hydrocolloids obtained from brown and red algae, respectively.
•agar is one of the commercial products obtained from gelidium and Gracilaria and are used to grow microbes and in preparation of Ice creams and jellies.
➡️iodine :
•fucus and laminaria are rich sources of iodine.
