What would happen to co2 if there was less plants
MArishka [77]

Answer:

More carbon dioxide (CO2) would be in our atmosphere.

Explanation:

Plants undergoing photosynthesis take in carbon dioxide (CO2) and give out oxygen (O2). They essentially use the CO2 to make sugars that keep them alive. Excess plant CO2 is then given off back into the environment, just like how we exhale CO2 after taking a breath.

So, no plants to take in the CO2 equals more CO2 in the environment.

Think of it kinda like this: I like Pop Tarts. If there is less or none of me in the world, there are more Pop Tarts just... out there... waiting to be eaten.

Control and experimental groups. They repeated their experiment several times and found the results were the same.
Ira Lisetskai [31]

Answer: Experience 1 is the one that has the greatest reliability.

Explanation:    Because of this potential variation, biological experiments need to have a large sample size and preferably be repeated several times.  With more samples and repeating the experiment more often, the probability of arriving at a wrong conclusion due to random variation is diminished. As experience 1 has had several repetitions, it is the experience with a more reliable result.
