Humans are heterotrophs and cannot synthesize their own food,so they cannot be producers.$3$. Humans can act as primary consumers (eating plants,$T_2$),secondary consumers (eating herbivores,$T_3$),or tertiary consumers (eating carnivores,$T_4$).$4$. Since humans are not producers,they cannot be placed in the primary trophic level $(T_1)$.
