In terms of various trophic levels of a food chain, which of the following organisms belong to the same level?

Snake and Grasshopper
Grass and tree
Lizard and elephant
Bacteria and grass

Solution:

In a food chain, organisms are grouped into trophic levels based on how they obtain their energy. Grass and trees share the same role in an ecosystem.

Both grass and trees are Producers (also known as Autotrophs). They belong to the First Trophic Level (

T_1

) because they both capture solar energy through photosynthesis to create their own food.

Organism Pair	Trophic Levels	Why they don't match
(A) Snake & Grasshopper	Secondary Consumer ( $T_3$ ) vs. Primary Consumer ( $T_2$ )	The grasshopper eats plants; the snake eats animals.
(B) Grass & Tree	Producer ( $T_1$ ) & Producer ( $T_1$ )	Both are the base of their respective food chains.
(C) Lizard & Elephant	Secondary Consumer ( $T_3$ ) vs. Primary Consumer ( $T_2$ )	Elephants are herbivores; lizards are typically carnivores/insectivores.
(D) Bacteria & Grass	Decomposer vs. Producer ( $T_1$ )	Bacteria break down dead matter, while grass creates new organic matter.
