Answer:

1. Cycle - A cycle is the series of events regularly repeated in a particular order or sequence. The cycle can be repeated at a particular time or whenever they are started.

2. Material - It is the mixture or combination of various substances in a particular ratio. It can be living or nonliving and makes an object or organs.

3. Ecosystem - It is a geographical area where different forms of life or living or biotic factors and abiotic factors interact with one another and live in a stable form.

4. water cycle - hydrologic cycle or water cycle the cycle that deals with the movement of the water above or below of the earth through various forms. Sun plays important role in evaporating the water.

5. Nitrogen cycle - It is the cycle that deals with the movement of nitrogen or nitrogen compounds through various spheres of earth. It is a biogeochemical cycle which means it converts to various chemical compounds and interacts with the biosphere and atmosphere.

6. Oxygen Carbon - Dioxide Cycle - oxygen and carbon dioxide are the main part of the living organism to produce energy. Plants use atmospheric carbon dioxide to produce energy and release oxygen for cellular respiration.

7. Bacteria - it is a microscopic unicellular prokaryotic organism that different from eukaryotic and archaea organisms. These organisms lack a nucleus and double-membrane-bound organelles.

8. Evaporation - it is the process of the water cycle in which heat comes from the sun converts water into water vapor that moves to the atmosphere and forms clouds.

9. Nitrification - It is one of the processes of the nitrogen cycle in which oxidation of NH3 to nitrite followed by the oxidation of the nitrite to nitrate with the help of organisms present in the roots of plants and soil.

10. Photosynthesis is the process that converts light energy to chemical energy with the help of atmospheric water and carbon dioxide and makes glucose and oxygen.
