Detailed explanation-1: -Humans are both primary and secondary consumers. Humans are essentially carnivores. They feed directly on producers likes vegetables becoming the primary consumers. Humans also feed on primary consumers like chicken and goats thereby becoming the secondary consumers.

Detailed explanation-2: -Humans are omnivores, therefore can occupy different trophic levels in a food chain. He can be the primary consumer if he feeds directly on green plants. He can also be the secondary consumer if he feed on a primary consumer (like goat) which directly eats plants.

Detailed explanation-3: -At the top of the scale are meat-eaters that don’t have any predators themselves, such as polar bears and orca whales. Instead, we sit somewhere between pigs and anchovies, scientists reported recently. That puts us right in the middle of the chain, with polar bears and orca whales occupying the highest position.

Detailed explanation-4: -The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain.

Detailed explanation-5: -Humans are considered secondary consumers. They obtain their food from producers (plants) and other animals (herbivores and consumers)
