How do plants contribute to the carbon cycle? a. When plants respire, they release $\mathrm{CO}_{2}$ into the atmosphere b. When plants photosynthesize, they consume $\mathrm{CO}_{2}$ from the atmosphere. c. When plants photosynthesize, they provide oxygen to heterotrophs. d. When plants emigrate, they transport carbon molecules between ecosystems. e. Both a and b are correct.

Okay, so we're in problem. 10 of chapter 45. Looking at how plants, contrary to the carbon cycle. Now, if it's if it's daytime right here at daytime, have a nice little plant here during the day. Time is gonna take in taken light energy, right? And it will also take in take in, uh, carbon dioxide CIA, too. You don't release oxygen and sugar, right? And this is, of course, the photosynthesis. But unless you are, say, the plant that lives only in Alaska during June and no other time at some point you will experience night, okay? And so if we are here in nighttime plant, then you start to experience respiration instead. Okay, so we're a little plant here and during the process of respiration, uh, actually take in oxygen and this is similar to two in humans. Do respiration. Right? And then then out. Ah, you produce carbon dioxide. And so if you look at our our options for problem 10 it's saying when plans photosynthesize be, they consume CEO to from the atmosphere. Well, that checks out, but also for part A. When they're in respiration, they release carbon dioxide also checks out. So the answer that we want is both a and B. So choice d

Plants are very important in cycling, nutrients and energy flow of an ecosystem. Plants take energy in the form of sunlight and turn it into chemical energy. This can then be used by other organisms. Plants use carbon dioxide and water to create sugars and oxygen, which are important chemical nutrients in an ecosystem. Lastly, the process of photosynthesis in plants creates heat, which is important for other.

Things. Question. Why must auto traffic organisms also re spire or ferment in addition to fixing carbon dioxide? So we know that autotrophs usually fix this carbon accent by way of taking the carbon dioxide from the air and use sunlight in conjunction with it to create glucose. Now let's just put this down here. Autotrophs will take carbon dioxide plus sunlight. This is in most situations, but there are also other conditions instead of sunlight. But let's just say some light here, for example, and they will convert carbon dioxide and sunlight into glucose. Now, if we made glucose, we just left it there. That doesn't matter, because we can have glucose sitting around. We're not getting energy into the cells. We need to take this glucose, and we need to convert it to any T P and then this. 80 Pekan. Go onto the cells and be harnessed for all cellular work. Neat. Now, if we don't do that, Google's just sitting around. That is not useful for both autotrophs and hetero troves, so autotrophs still need to respond iron or ferment. They inability uses glucose, and they need to be able to convert it into a teepee we just can't have the the glucose sitting around. That's not gonna give the cells any advantage. So the autotrophs still I need to perform some sort of respiration. So either it is anaerobic or aerobic. They still need to be able to get the glucose into a usable form, which would be once again a teepee. So how did they do this? Well, they must, um, be able to once again re spire or ferment. So, uh, why? Because our answer here, why must they do this? Because the autotrophs must convert, um, the must convert to glucose. They produce into a usable form such as E t. P. And thus use that energy for all their cellular work needs. So that would be your answer for this question.

So the question here basically asked, How do plants obtain carbon and nitrogen? So carbon and nitrogen are basically found in various minerals that plants can absorb using their roots. And it is also found in carbon dioxide that plants intake in order to produce oxygen. As a side, I'm effect.
