No, animals breath in oxygen and breath out carbon dioxide. Plants breath in carbon dioxide and breath out or release oxygen, this also includes algae which is a type of plant.
Algae can release oxygen and take up carbon dioxide that permeates cells.
It feeds certain fish and helps contribute to the oxygen in the water in which it grows.
No, they produce Co2 which is used for plants to breathe then the plants produce oxygen. This is wrong. Green algae produce 70 to 80% of the oxygen on earth. We would not exist without them.

Photosynthesis
Because of algae growth, fish waste, the amount of oxygen decreasing because the fish are breathing it.
When Algae runs out of the proper nutrition it needs such as phosphates and other minerals it dies. Algae then dies and starts to decay during the decaying process Algae uses oxygen which is also why fish die from lack of oxygen. So to answer this question yes Algae does decay and consume oxygen.
The pacific ocean. Green algae in the oceans produce the majority of the Earth's oxygen. The rainforests add a much smaller amount.
eutrophicationeutrophicationFertilizer in a lake helps algae grow. Up to a certain point, that is good. The algae turns carbon dioxide into oxygen and adds oxygen to the water. However, after that point, the algae covers the lake. Oxygen from the air can not get to deeper water. Dead algae falls to the bottom of the lake and decomposes. The process of decomposing uses up oxygen. The amount of oxygen in the lake drops below the point where fish can survive. Thus, over fertilization leads to a fish kill.
The useful effects of algae is that it provides oxygen for various living things. Algae is also a food resource for humans and fish. Algae can become harmful if they produce toxins. Too much algae in the water can kill fish because the algae consumes a great amount of oxygen and can block the sunlight from reaching underwater.
Plants, especially through the process of photosynthesis, release oxygen into the atmosphere. Photosynthesis involves the absorption of carbon dioxide and the release of oxygen as a byproduct. Additionally, certain types of algae and cyanobacteria contribute to oxygen production through photosynthesis in aquatic environments.
