Polypeptides are chains of amino acids linked by peptide bonds.
All prokaryotic cells are divided into two domains: bacteria and archaea.They are divided into 2 domains, because bacteria and archaea are very different:Archaea aren't susceptible to antibiotics, and bacteria are.Archaea have introns, or non-coding parts of genes that regulate gene expression, in some genes, while bacteria lack introns altogether.Archaean and bacterial cell walls are different because bacteria use peptidoglycan, a polymer of sugars linked with polypeptides, in their cell walls, while Archaea do not have true peptidoglycan. TThe organisms in domain Bacteria have unbranched carbon chains in the phospholipid bilayer, but the organisms of domain Archaea can have branched chains.
Long chains of sugars are polysaccharides. These large molecules are made up of numerous monosaccharide units linked together through glycosidic bonds. Examples include starch, glycogen, and cellulose.
When single sugars are linked together into long chains, the result is a complex carbohydrate known as a polysaccharide. This type of carbohydrate serves as a source of energy and structural support in organisms. Examples of polysaccharides include starch, glycogen, and cellulose.
Proteins are made from long chains of smaller molecules called amino acids. Amino acids are biologically important organic compounds that are composed of amine and carboxylic acid.
Many food chains linked together makes up a food web.
If I'm understanding your question correctly, it's called an ecosystem.
a recipe
covalent bonds between chains of molecules of a polymer or polymers, fastening the chains together. See also cross-linked polymer, under polymer.

Polypeptides are chains of amino acids linked by peptide bonds.
"Chains of discrimination" is an example of a metaphorical or extended metaphor rhetorical device, where the idea of discrimination is linked or connected to chains to emphasize its pervasive and restrictive nature.
Enzymes
The monomer used to build proteins is called an amino acid. Proteins are composed of long chains of amino acids linked together by peptide bonds, forming polypeptide chains.
The dimer in lipids is called a phospholipid. It consists of two fatty acid chains linked to a glycerol molecule, with a phosphate group attached to the glycerol backbone. These molecules are essential components of cell membranes.
