a. primary
b. secondary
c. tertiary
d. quaternary

Quaternary

Explanation:

Living organisms found in the ecosystem are involved in a feeding chain in order to obtain energy needed for their metabolic processes. This chain is called Food Chain and it consists of steps in which organisms are classified based on their feeding behavior. This step is called TROPHIC LEVEL. The trophic level begins with PRODUCERS up to QUARTENARY CONSUMERS.

As one organism eats another, energy in form of biomass is transferred to such organism. However, only a little fraction of the energy is transferred to the next trophic level as most of the energy (80-90%) is lost as heat during the organism's metabolic activities. Hence, the higher the organism on the TROPHIC LEVEL, the lower the amount of available energy.

Based on this, the QUARTENARY CONSUMER is the highest on the trophic level and will contain the smallest amount of energy available.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
