Title:
What happens when Co2 level increases? How does it
affect plant growth and the world?
Problem:
How do increased Co2 levels affect plant growth and the world?
Hypothesis:
Our hypothesis is that if the Co2 level increases then the plant growth will increase as well, because plants need Co2 to live. If the level of Co2 decreases that means that there would be as much plants.
Materials:
No materials are needed
Procedure:
Since we couldn't do an a experiment on this we did research. We did research on how plants are affected by Co2 when its level is increased and decreased.
Observations:
We noticed that since plants need Co2, its okay for it to increase, because when its mix with the other treatment warmings it can decrease the plant growth only if the level of the warmings were high. If the level of the warming are equal then the plants will actually grow taller. The three warming are nitrogen, water and temperature.
We also found out that precipitation and nitrogen produce an increase of 84 percent (the largest) but when adding Co2 it decreases to about 40 percent.
Conclusion:
Our data rejected our hypothesis. It rejected it, because we predicted that the plant growth is increase if it was Co2 alone, but our observations show that it could only happen if there are other air masses involved. There are more studies going about how Co2 acts around plants when a different air mass is added.

What do scientists think will happen?
According to scientist research they have found that increasing the amount of Co2 in the air can help plant growth, but too much Co2 can cause problems. As of now carbon dioxide levels are going up. In 1958 the amount of carbon dioxide (measured in part per millions) went form 315 to 365 and the rate is going up. Scientst say that in the next 100 years it could double to 700 PPM.
What are some scientists doing?
There are different scientists doing different things. There are scientists who are experimenting carbon dioxide with different materials. They had tested it on soil and were expecting a increase of 30 percent. But that didn't happen, it actually decreased soil organic matter.
Scientists have also tested it in different natural gases. They tested temperature, nitrogen and precipitation alone first. The result was that it increased plant growth. But when they added carbon dioxide it decreased 40 percent.

What will happen to the plants if Co2 increases? What if Co2 decreases?
A theory:
Studies shows that if Co2 increases, it'll be okay, because when carbon dioxide mixes with the other warmings in the atmosphere then the percentage of other warmings will actually decrease. The warmings are nitrogen, water and temperature.
Scientists say that by 2050 carbon dioxide will increase 43 percent.
If Co2 decreases then that'll be good too for the human life. Scientists believe that Co2 will decrease human life by eight years.

Do all plants use carbon dioxide?
There are plants that don't need carbon dioxide to survive.
The plants that use carbon dioxide to live are plants called Autotrophic plants, Semiparasitic plants and Insectivorous plants. The plants that don't use carbon dioxide are Holoparasitic plants and Mycoheterophyes plants.
Need Carbon dioxide:
Autotrophic plants are plants that only need solar energy, carbon dioxide, water, and a few minerals.
Semiparasitic plants take carbon dioxide, but not by themselves. They have a host. When a plant has a host, it means that they are attached to another plant and thats how they can get their food.
Insectivorous plants trap there food. Its okay if they go without food, but they'll be stronger if they have something to eat once in a while.
Don't need carbon dioxide:
Holoparasitic plants are plants that have to be connected to a host. These don't do photosynthesis and don't have any green parts. They get their food, water and nutrients from their host plant.
Mycoheterophytes plants hosts are trees. They get their food and water from them. And mycoheterophytes plants don't do photosynthesis but their host does it for them or you can say that it shares with the mycoheterophytes plants.

Vocabulary:
Carbon dioxide(Co2): a colorless, and odorless gas that is in the atmosphere. It is formed from coal, coke and natural gas.
