Class 12 Biology Ecosystem: NCERT Solutions for Question 4

Answer A

There are no other producers except plants .so option D is the correct one

Option d is correct

Option d

Option "A"is correct because if u remind secondary productivity then secondary producer are harbivores i.e. primary consumer so i think option A is more appropriate rather than option D

no, herbivores are primary consumer .So correct option is d

May be d option i.e.none of the above is correct from my point of view.

Herbivores is right

Surely herbivores as they act in similar manner in food chain for carnivores as primary producer viz plants act for primary consumer viz herbivores

Now I see! This does make sense because although herbivores are consumers, they are a source of food for carnivores. Since they eat plants, they are eating the primary producers, making them primary consumers. But when carnivores eat them, they turn into secondary producers because they are producing the energy for the meat - eaters since they ate the plants first. So this means that technically, secondary producers are also primary consumers.
