1.The major source of energy in a food chain originates from the sun

2.Solar energy is created by nuclear fusion in the sun, fusing hydrogen into helium

3.The waves reaching Earth warm the planet and make life possible, called the greenhouse effect

AStatements 1, 2 and 3 are true ✓ Correct

BOnly statements 1 and 2 are true

COnly statements 2 and 3 are true

DOnly statements 1 and 3 are true

Correct answer: (A) Statements 1, 2 and 3 are true

Explanation

All three statements about solar energy and the food chain are true.

Statement 1 is right because the sun is the primary energy source of every food chain.

Statement 2 is right because solar energy comes from nuclear fusion of hydrogen into helium.

Statement 3 is right because incoming radiation warms Earth and sustains life through the greenhouse effect.

Green plants capture this solar energy and pass it up the food chain.

Only a small fraction of energy transfers to each higher trophic level.
