Living organisms are composed of four main elements: Carbon, Hydrogen, Oxygen, and Nitrogen. These four elements make up approximately 96% of a living organism's mass. Other elements, such as Phosphorus, Sulfur, Potassium, Calcium, and Magnesium, are also present in living organisms, but in smaller amounts. Carbon Hydrogen Oxygen Nitrogen Phosphorus Sulfur Potassium Calcium MagnesiumAltogether, there are nine elements that make up a living organism. The proportion of each element can vary significantly, depending on the organism and its environment.

Vertebrates
It depends which organism you are referring to.
a vertebrate is a living organism with a backbone and an invertebrate is a living organism without a backbone
Vertebrates are those that have a skeletal system.
A living organism with a segmented backbone is a vertebrate.
Vertebrates are those that have a skeletal system.
because it is an organism
Yes. Multicellular means an organism has more than one cell. Kangaroos are vertebrates and all vertebrates are multicellular.
No, bacteria are not vertebrates. Bacteria are a class of micro-organism, and as such, cannot be classed as vertebrates. Vertebrates are living organisms which have a "backbone", i.e a series of vertebrae which support their body structure and allow movement. The name"vertebrates" comes from the presence of these "vertebrae".
Animals with backbones are called "vertebrates." Animals without backbones are called "invertebrates."
A chemosynthetic organism uses sulfur or other elements as a source of energy.
