Answer 1

Dear Student,

The first trophic level in a food chain is always a green plant because green plant are the producers they make their own food and which is consume by other trophic levels. Green plants have a special pigment called chlorophyll which absorbs sunlight, and converts it into chemical energy by the process of photosynthesis.
