Using the 10 percent rule, explain why there is typically smaller populations of quaternary consumers compared to primary consumers in an ecosystem.

any time a source of energy is obtain using natural means, the 10 % rule will apply. 10 % rule means when energy is passed in an ecosystem from one trophic level to next, only 10% of the  energy  will be passed on. A trophic level is the position of organism in the food chain.

So Quaternary consumers are at the top position in the food chain, they will receive less energy from the food as compared to the primary consumers which are at the bottom of the food chain. so when getting less food and less energy, Because of this, the populations of Quaternary consumers are usually the smallest out of the populations in the food chain.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
