What are trophic levels? Give an example of a food chain and state the different trophic levels in it.

(N/A) Trophic levels are the specific stages or steps in a food chain through which energy is transferred from one organism to another.
Example of a food chain:
Grass $\rightarrow$ Grasshopper $\rightarrow$ Frog $\rightarrow$ Snake $\rightarrow$ Peacock
The different trophic levels in this food chain are as follows:
$1$. Grass (Producer): First trophic level $(T_1)$
$2$. Grasshopper (Primary consumer): Second trophic level $(T_2)$
$3$. Frog (Secondary consumer): Third trophic level $(T_3)$
$4$. Snake (Tertiary consumer): Fourth trophic level $(T_4)$
$5$. Peacock (Quaternary consumer): Fifth trophic level $(T_5)$
