Grass, like all plants, does not trap all the sunlight. It only traps a small percentage of the sunlight that hits it, typically through photosynthesis. The efficiency of this process is low, and only a fraction of the sunlight energy is converted into chemical energy.

Here’s a breakdown of the other options:

B. Trap a small percent of the sun energy – This is true; plants, including grass, trap only a small fraction of the sunlight through photosynthesis.

C. Are primary producers – Grass is a primary producer in the food chain, as it synthesizes its own food using sunlight (through photosynthesis).

D. Are eaten by primary consumers – Grass is eaten by primary consumers like grasshoppers in the food chain.

E. Contains chlorophyll – Grass contains chlorophyll, which is essential for photosynthesis.
