Photoautotrophs are organisms that can utilize light energy from sunlight and elements (such as carbon) from inorganic compounds to produce organic materials needed to sustain their own metabolism (i.e. autotrophy). Such biological activities are known as photosynthesis, and examples of such organisms include plants, algae and cyanobacteria.
While many chimpanzees are naturally hydrophobic, Sakamaki (1998) found that those in Mahale have been observed to submerge themselves into freshwater and eat algae. [7] This observation is the first documentation of a primate using algae in the wild as a food source and is an important marker of possible adaptation in the species.
An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds, which can be used by other organisms. Autotrophs produce complex organic compounds (such as carbohydrates , fats , and proteins ) using carbon from simple substances such as carbon dioxide, [ 1 ] generally using energy from light or ...
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. [1] [2] When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
Heterotrophic nutrition is a mode of nutrition in which organisms depend upon other organisms for food to survive. They can't make their own food like Green plants. Heterotrophic organisms have to take in all the organic substances they need to survive. All animals, certain types of fungi, and non-photosynthesizing plants are heterotrophic.
Sea lettuce as a food for humans is eaten raw in salads and cooked in soups. It is high in protein , soluble dietary fiber , and a variety of vitamins and minerals , especially iron . [ 5 ] However, contamination with toxic heavy metals at certain sites where it can be collected makes it dangerous for human consumption.
BETO organized an Algae Program dedicated to researching and improving the viability of algae as an energy source. EERE's official page for the Algae Program lists goals including improving yields of algae strains while decreasing expenses of growing algae, filtering the algae from the water, extracting the oils, and processing the biofuel.

The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. [6] Most edible seaweeds are marine algae whereas most freshwater algae are toxic. Some marine algae contain acids that irritate the digestion canal, while others can have a laxative and electrolyte-balancing effect. [7]
