Answer:
1. Photosynthesis: process that plants produce sugar
2. Nucleus: central part of an atom
3. Combustion: the process of burning in the presence of oxygen
4. Fission: a process that split atom
5. Solar energy: energy from the sun
6. Atom: a nucleus surrounded by electron
7. Energy: capacity for doing work
Step-by-step explanation:
1. Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose(sugar) from carbon dioxide and water
2. The protons and neutrons cluster together in the central part of the atom, called the nucleus
3. Combustion is the process of burning something.
4. Fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei.
5. Solar is a form of energy gotten from the sun.
6. Atom: every atom is composed of a nucleus and one or more electrons bound to the nucleus.
7. Energy is the ability to do work
