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: -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.
Detailed explanation-4: -For example, if secondary consumers were removed from a certain food chain, the primary consumers would increase in number, causing the producers to be consumed in much larger quantities. Also, the tertiary consumers would decrease in number because they would not have any food to feed on.
