Creosote bushes present one of the most important species in the Mojave desert ecosystem. They are one of the main producers in this ecosystem, meaning that they convert the energy from the Sun into a form of energy that other organisms in the ecosystem can use.

That would be biochemistry.
Answer: The building blocks of proteins are amino acids, which are small organic molecules that consist of carbon atoms linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain.
Translation:
Los componentes básicos de las proteínas son los aminoácidos, que son pequeñas moléculas orgánicas que consisten en átomos de carbono unidos a un grupo amino, un grupo carboxilo, un átomo de hidrógeno y un componente variable llamado cadena lateral.
