Natural cycles of life

Lyrics

Water Cycle x2

It happens everyday

It starts from evaporation

From the ocean to the sky

Then goes condensation

And that leads to precipitation

Water Cycle x2

It happens everyday…

Carbon Cycle

Lyrics

Old mcdonald had a farm e-ya-e-ya-oh

Plants take in carbon dioxide during photosynthesis

Animals eating plants they get carbon too

Respiration happens turns carbon back in the air

Photosynthetic organism release carbon too

Old mcdonald had a farm carbon cycle

Nitrogen Cycle

Lyrics

Nitrogen Cycle

Nitrogen nitrogen starts of as a gas

Nitrogen nitrogen goes into the plants

To spread the nitrogen around omnivores eat the meat

Nitrogen nitrogen the omnivore will poop

Then these smelly nitrogens will go into the roots

Nitrogen fixing bacteria is found on plant roots

It turns into ammonia

Water Cycle: It happens every day in our life. First it starts from evaporation (water going up). Second Condensation, when water stays up and last precipitation, when water goes down (Rain)

Carbon cycle: Complex molecule in living organism contains mostly carbon. Carbon is also important in the ecosystem. It enters the ecosystem by producers which take in carbon dioxide during photosynthesis. When other organism eats the producer they would also get carbon. Carbon would get back into the atmosphere in form of carbon dioxide by cellular respiration from the consumers. Plants would also release carbon dioxide as well, when they do cellular respiration. Other forms of carbons are fossil fuels, coals, oils, natural gases, dead animal body and plants from millions years ago that are underground. As we burn fossil fuel, they would release carbon and returns it into the atmosphere as carbon dioxide. Nowadays, human have been affect the carbon cycle which is one of the big concern that the world is having right now. (FROM THE TEXT BOOK)

Nitrogen cycle: Nitrogen is very important to living things on earth. Nitrogen gas is about 78 percent of the atmosphere. Every living organism requires nitrogen in order to build protein. There is only one organism that could take the nitrogen gas and directly use it is the nitrogen-fixing bacteria, others organisms depends on the bacteria. The nitrogen-fixing bacteria are on the plants roots, but not all species of plants have these bacteria on their roots. Some bacteria are not in or on the plants roots they are also living in the soil so plants that doesn’t has the bacteria on their root would get nitrogen from the soil. Nitrogen-fixing bacteria has a very important role in the nitrogen cycle, they would fix the gas in a way that plants would be able to use, which is ammonia. The energy that they use fix the gas into ammonia is the sugar that were produced by the plants. When animals eat the plants or other animal they would also get their nitrogen that they needed. Nitrogen would return into the atmosphere by decomposers, which will turn nitrogen back into ammonia. (FROM THE TEXTBOOK)
