Hello there.
00:02
I see that you have a few questions, just a few brief questions.
00:07
They want to know do all organisms depend on the sun for their energy needs? and i see that you have the site, that you have to cite your own examples to support this answer.
00:22
And for this site, i got this site from the science line.
00:32
Ucsb .edu, where they said not really because there are living organisms that live in the very deep oceans near deep sea fence that do not need the sun to survive.
00:46
And also there are bacterias like tardigrades that live in hot springs and other volcanic waters that get their energy from chemical release, from chemicals release.
01:01
As a result of volcanic activities.
01:05
Another question that they asked is, why is photosynthesis critical to the survival of most organisms on earth? well, the reason for that is because it is the number one source of oxygen in the atmosphere, and without it, the carbon cycle could not occur.
01:27
Oxygen requiring life would not survive, and the plants would die.
01:32
So that's the main reason why.
01:34
Plus with photosynthesis, it captures the energy.
01:37
So it captures the energy from the sun and to try to chemically convert that into oxygen, which is what is needed to live.
01:48
And then the last question is briefly discussed the different types of heterotropes...
