We know that plants take in co2 and release o2. In this process, which element must remain in the plant?how do you know?

carbon is retained And incorporated into glucose via photosynthesis.

Explanation:

There is no need to look for complexity here. The obvious answer is the right answer. Take in CO2, release O2 - what remains? Yes, C.

A more detailed explanation is that plants use sunlight to make glucose from CO2 and water (photosynthesis).

6CO2 + 6H2O —> C6H12O6 + 6O2

b) the inside picture would look at a very high temperature in a very low ph
