Green Algae

Green Algae is a microscopic protist, invisible to the human eye, that has an immense impact on both humans and the ecology in its natural environment. Green Algae is mostly found in fresh water and there are approximately 6,000 species within the family of green algae with almost all of them having chloroplasts. All Green Algae are photosynthetic organisms and thus produce oxygen from CO2. Photosynthesis removes CO2 from the atmosphere and replaces it with oxy-gen, which is a contribution to the slowing down of the process of global warming. The survival of fish and other organisms depends on oxygen, which is used by a multitude of life organisms to acquire energy for cellular respiration.

Green Algea is Photoautotrophic in that these organisms function as "primary producers" con-verting sunlight and nitrogen into oxygen and food for other animals. The provision of a major global food source in the sea, and meanwhile outside, is another key positive function of Green Algae. As a base of the food chain in many habitats to a multitude of organisms around them, Green Algea is the key fundament of survival of those organisms all around the globe.

If Green Algae were no longer present, the food chain would fall apart. A large number of or-ganisms would become extinct due to starvation. The chain would go from a large variety of fish starving and eventually succumbing to extinction causing other organisms that live of fish to starve, thus causing again others and so on – the idea of a chain. Simply put, many organisms higher up in the food chain depend on the (continued) presence of Green Algae in the food chain.

To sum up, it could be said that Green Algae performs a key role on global living organisms bal-ance providing oxygen through photosynthesis and representing an elementary building block in the food chain. The effects of this
