Question

The passage of materials from producer through primary, secondary, tertiary and quaternary consumers is known as..........

Answer 1

• A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
• At the base of the food chain lie the primary producers which are autotrophs and are most often photosynthetic organisms such as plants, algae, or cyanobacteria.
• The organisms that eat the primary producers are called primary consumers and are usually herbivores.
• The organisms that eat the primary consumers are called secondary consumers which are generally meat-eaters—carnivores.
• The organisms that eat the secondary consumers are called tertiary consumers which are carnivore-eating carnivores, like eagles or big fish.
• Some food chains have additional levels, such as quaternary consumers—carnivores that eat tertiary consumers.
  

So the correct option is 'food chain'.
