I have written your answer on my computer and took a photo here it is!!
C. Lithosphere
Lithosphere is where crust, landforms, etc. can be found.
Its bc plants can only take in so much nitrogen like compounds (nitrates, ammonium etc) to keep a stable ph level so ammonium is positively charged and nitrates are negatively charged they release hydrogen to equal the ph levels but since it’s already getting ammonium in the cycle it can’t receive more and the ratio must be compatible with the plants therefore not different.
Also, plants can’t take it in bc it needs the bacteria to break the ammonium down into a usable compound. Like nitrates.
I’m sorry if that was contradicting. I’m trying my best. :)
➜ Plants do not move. In a large plant body there are many dead cells like schlerenchyma which provide strength to the plant but do not perform any cellular function. As a result they requires less energy. Animals, on the other hand, need energy for different activities like movement or search or food. So, they require more energy.
Darwin called the ability of an organism to survive and reproduce in its environment fitness.
Some organisms were fit to do all of these things, whereas others were not.
