6. What is nuclear fusion?
Answer It is a nuclear reaction in which atomic nuclei of low atomic number fuse to
form a heavier nucleus with the release of energy.
7. What is nuclear fission?
Answer It is a nuclear reaction in which heavy nucleus splits spontaneously or on
impact with another particle with the release of energy.
8. What is photosynthesis?
Answer It's the process by which autotrophs produce Sugar by getting energy from
the Sun to make their own energy.
9. Explain how the sun's energy moves through the food chain.
Answer Producers absorb the sun's energy directly, and the primary consumer eats.
And get some energy, and then the secondary consumer eats that for energy, and soon,
eventually, the organisms will decompose with the help of decomposers and
decomposers get their own energy from doing that.
