✨Heya!✨

The first trophic level of the food chain is always occupied by green plants which are termed to be producers. This is because producers absorb sunlight, abiotic factor and fix it into food chain. This energy is transferred to organisms in other trophic levels of the food chain.

Answer 2

The first tropic level in a food chain is always green plants because green plants are Autotrophs and make their food by own with the help of sunlight and all other animals including Humans are Heterotrophs and depends on plants for their food.

So, the first tropic level in a food chain is always green plants.

The process by which green plants make their foods is called Photosynthesis.

Reaction by which green plants make their own food is given below :-

6CO2 + 6H2O ------> C6H12O6 + 6O2

Name of the compounds are :-

CO2 = Carbon dioxide (gas)

H2O = Water (liquid)

C6H12O6 = Glucose (simple food)

O2 = Oxygen (gas)

Green plants make their food in the presence of sunlight and chlorophyll.
