Energy Flow and Pyramids
Просмотров 1,5 тыс.7 лет назад
This video describes how energy enters, moves through, and exits ecosystems. It starts by discussing the differences between gross primary productivity and net primary productivity, and how to measure these values. Food chains, food webs, and energy pyramids are all used to show what happens to the energy as it moves through the ecosystem, culminating in a comprehensive model that connects all ...

How did you take 6.33 value. Isnt it 1.58...
Beautiful !
It really helps me think stuffs with verbs, so that I can connects the keywords and bring more ideas by myself. Appreciate your sharing!

i love you
thanks!!
i thought it was pronounced as Chi as in chi cago
Sheets is so poorly made, but at least it's free
you saved me
This is a slay thank you
So helpful!
Awesome
wow really fantastic!
there really should be an easier way to do this
thank you professor God bless you
Cool THX
Honestly, this is somewhat confusing. With arrows pointing every way possible, and some of the weak linking words I couldn’t use this map as a study tool. It would be more productive for me to just throw this into Anki.
I love you for this
GRACIAS!!!! Well done! Clearly and cleverly stated.:)
finally the video that answered all my questions! good job and thank you 💪🏼
Bravo!
thanks for making good presentation
I'm relieved...thank you so much❤ for this..
Wow thanks so much!! Saved me so much time
can anyone help me understand why this is a one-tail test? H0: ratio is 1:1; H1: ratio is NOT 1:1; isn't this should be a two-tail test?
I need to watch it twice to confirm my understanding. Thank you for a clear explanation
pure gem.. thanks a ton
Excellent Video, Thank you for posting, helped me understand Chi Square Test
You are a legend sir 🙏
watching this and I have a submission in two days, really helped thank you Doc!
The mars example was awesome, thank you!
Im confused. When I calculate the SD at 4:25 I get ~5.47. I‘m adding them all up and divide by 12 to get the mean. Then subtract that mean from each value, square it and add it up, dividing the result by 11 and take the square root of that. What am I doing wrong? Excel gives me the same result, far from 6.33.
Minor calculation mistakes but kudos to intuitive explanations.
Good
I always explain it this way to students. SD is a measure of how big the spread is between samples. SEM is a measure how exact we know the average (or mean). It starts to get interesting when SD is relatively big. At that point one could argue how valid the test actually was. Because it's perfectly possible that the SD is very big (individual samples are widely spread) but SEM is quite small at the same time.
Thank you!
Wonderful
Thank you very much, it's become more more clear for me.
I would have topped in maths if I had found you sooner. 😅
This is the best explanation. Thank you
Perfectly explained!!!!
IB chem students do be loving this video
could you click your laptop any harder?
Leave the poor guy alone 😂
thank you for the great video! currently working on my MA thesis and desperately needed to review the basics :)
Such a beautiful piece. Am fully equipped with knowledge now.
great great video!
Finally someone knows how. Whenever I look it up it just tells me how to add error bars to each graph of the series.
Wonderful video!
Very good video
good explanation ..thanks sir
