b. from microorganisms that live in soil
c. from carbon dioxide in the atmosphere
d. from animals that feed on the plants
The answer is C: From carbon dioxide in the atmosphere! It's because when we breathe in the oxygen that the plants produce we breathe out carbon dioxide and the plants kinda do the same thing just instead of breathing in oxygen they breathe in carbon dioxide and breathe out oxygen!
An increase in the amount of greenhouse gases in the atmosphere
A decrease in the amount of air pollution
A cooling effect on Earth’s climate
2. Evaporation occurs when a ____ changes into a ____. *
Solid; liquid
Gas; liquid
Liquid; gas
Solid; gas
3. What is the definition of anaerobic? *
Producing oxygen
Producing methane
Containing bacteria
Lacking oxygen
4. What is the purpose of regularly mixing a compost pile? *
To decrease the temperature in the compost pile
To reduce the amount of oxygen in the compost pile
To prevent the production of methane in the compost pile
All of the above
Answer:
An increase in the amount of greenhouse gases in the atmosphere
Liquid; gas
Lacking oxygen
To decrease the temperature in the compost pile
Explanation:
1. Methane is one of the greenhouse gases. When these gases are released into the atmosphere, they increase the temperature of the earth surface because they trap heat within the earth. Other examples are carbon dioxide and water vapor.
2. Evaporation is a phase change from liquid to gas. During this process, heat is supplied to a liquid. When the molecules of the liquid gain enough energy, they then begin to break off into gaseous form. The reverse process of evaporation is condensation.
3. Anaerobic is a process that lacks oxygen. Aerobic processes are carried out with the availability of oxygen.
4. The reason why compost should be regularly mixed is to decrease the temperature in the compost pile. Portions of the compost can have a higher temperature than other parts. Therefore, mixing the compost will help to redistribute the heat in the compost.
