Name the five main levels of study in ecology from smallest to largest.

Video transcript

Hello everyone and welcome to today's video. So today we need to identify the option which correctly describes the sequence of the level of ecology from the smallest to largest. So in order to accelerate this problem, we're going to be starting by the largest level here we have either community, individual biosphere and biosphere. Again on answer choice D if we compare this, we're going to realize that this biosphere ecology is going to be the largest one because this includes all ecosystems, all regions on earth where life is present, which is more which is larger than a community or a single individual Because of this, we're going to cancel out answer choices A and B. And we're going to be left with C. And D. Let's move on to the next one. We are going to be comparing in an individual and an ecosystem here. Remember that an individual is a single organism. Whereas an ecosystem is this large area which contains a biotic and biotic factors. So it contains many organisms. Because of these. An ecosystem is going to be much bigger than a single individual. So we're going to cancel our answer choice C. As well. And this is going to leave us with answer choice E as the correct answer for this problem. I really hope this video helped you and I have to see you on the next one
