Which of these statements is true about ecosystems? a, non -living components are usually not considered part of them.
00:08
B, biodiversity is lesser at the equator.
00:11
C, none of these.
00:13
D, the ecosystem is composed of living organisms only.
00:18
Or e, biodiversity is the same at the equator as at the other meridians.
00:23
Let's tackle for biodiversity first.
00:25
So biodiversity is greater nearer the equator, not lesser and not the equator.
00:30
The same.
00:32
So species, diversity increases at the equator.
00:41
Why? well, it's because of more intense sunlight.
00:46

00:52
So you need all of those plants performing photosynthesis getting the energy in...
