the table shows the commonly eaten foods of some organisms.

which groups contain both primary and secondary consumers?
oa and b
ob and c
oc and d
ob and d

Explanation:

• A primary consumer is an organism that eats producers (plants). A secondary consumer is an organism that eats primary consumers.
• Group B: Branches, barks, twigs, roots are from plants. So, the organisms in group B that eat these are primary consumers.
• Group C: Insects are primary consumers (if they eat plants) and leaves are from plants (so organisms eating leaves are primary consumers), nuts (from plants - primary consumer if eaten by an organism in this group) and bird - eggs (if an organism in this group eats bird - eggs, it is a secondary consumer as birds may be primary or secondary consumers themselves).
• Group D: Vegetables and fruits (from plants - primary consumer if eaten by an organism in this group), grains (from plants - primary consumer if eaten by an organism in this group), fish (could be primary or secondary consumers depending on what the fish eats. If the fish is a herbivore, it is a primary consumer. If it is a carnivore that eats herbivorous fish, it is a secondary consumer).

C. C and D
