Accepted Answer

Hi everyone. Let's look at the next question. It says in which zone does the majority of the ocean's primary production occur? Well, let's recall that in general content videos. The primary producers all over are photosynthetic organisms. So on land, that would be the green plants in the ocean, primarily the photosynthetic algae. Although there are some green plants in the context of sea grasses, but not nearly as much as there are photosynthetic algae because they harvest that energy from the sun that then other organisms can consume. So we need light for this primary production through photosynthesis to occur. So let's look through our answer choices and we see that choice C is the phonic zone, which is that shallowest zone in the ocean which receives enough light for photosynthesis to occur. And we look at our other answer choices. We can eliminate choices these which the same in all zones because the darker zones of the ocean will not have photosynthesis occurring and therefore not have much in the way of primary production. Choice A says the A phonics zone. Well, that little prefix A means without or not. This is that zone where there's little to no light. There's very little photosynthesis happening here. So this will not be the area of a lot of the most primary production. And finally, choice be the abyssal zone. Think of the word abyss here. This is the deep depths of the ocean where there is no light penetrating at all. And so no photosynthesis occurs here. So this will not be our answer. There are some organisms deep in the depths of the ocean that can utilize other chemicals of the source of energy, but that's just a tiny, tiny proportion of the total of the totality of the ocean. The majority of the ocean's primary production will be due to photosynthesis. So in which zone does the majority of that primary production occur. And choice see the fog zone. See you in the next video.
