Detailed explanation-1: -Without the presence of the primary consumer, there would be no origin of energy for carnivorous or subordinate consumers so no subordinate consumer would be able to exist in the ecosystem. There are only primary consumers in the ecosystem at the side of decomposers .
Detailed explanation-2: -In an ecosystem without primary consumers, there would be no food for higher consumers and they would experience a population crash.
Detailed explanation-3: -If there are not enough secondary consumers, then tertiary consumers face starvation (or worse-extinction) because they would no longer have a food supply. If there are too many secondary consumers, then they will eat more and more primary consumers until they are on the brink of extinction.
Detailed explanation-4: -Decomposers and herbivorous consumers are the only two members that directly receive energy from plants (producers). If plants were removed from the food chain, consumers would die because they would have no source of energy.
