This introduction can be intentional or non intentional. The invasive species affects the native species that live there by snatching the resources from the native species and using it for their growth and development.
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds between monosaccharides. A dehydration synthesis reaction forms a bond between carbon atoms in two monosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
