All of them exhale carbon dioxide.
Oxygen is a non-metal element and belongs to Group 16 (formerly Group VIA) of the periodic table. It has the atomic number 8 and is essential for sustaining life on Earth.
Protists are a diverse group of single-celled organisms that play important roles in various ecosystems. They can act as decomposers, predators, producers, and can also serve as food sources for other organisms. Some protists are responsible for producing a significant portion of the Earth's oxygen through photosynthesis.
No, cnidarians are not protists. Cnidarians are a diverse group of animals that include jellyfish, corals, and sea anemones. Protists are a separate group of eukaryotic organisms that are not classified as animals.
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. They aren't included in the same group as protists taxonomically. This explains why the cladists consider the protist a paraphyletic group.
Oxygen and silicon form the mineral group known as silicates. This group is the most abundant in the Earth's crust and includes minerals such as quartz, feldspar, and mica.

Minerals with the silicon-oxygen structure are classified into the group known as silicates. Silicates are the most abundant group of minerals on Earth and make up the majority of the Earth's crust. They are characterized by the combination of silicon and oxygen atoms in their chemical structure.

The first eukaryotic organisms on earth were likely single-celled organisms such as protists, which are a diverse group of organisms that have a nucleus and other membrane-bound organelles. These organisms are thought to have evolved around 1.6-2.1 billion years ago.

Protists are made up of very large, diverse group of organisms, including the plant-like protists (algae), fungi-like protists, and the animal-like protists (protozoans). They are all eukaryotic, and most are unicellular.
