008 – Energy Flow in Ecosystems
In this video Paul Andersen explains how energy flows in ecosystems. Energy enters via producers through photosynthesis or chemosynthesis. Producers and consumers release the energy from food through cellular respiration. An explanation of gross primary productivity and net primary productivity are included. Energy and biomass in ecological pyramids show energy efficiency.

this was the most confusing explnaition vid i have ever seen he gave me a headache
Love the way he teach🤗
Everyone subscribe!!! hes so close to 1m
Who's watching this for school in 2020 becuase of the corona virus?
8th graders at csat give me the answerssss (amoni)
Hi! Just curious, but can higher trophic levels get energy from other trophic levels that aren't right below it? I'm almost certain they can but I just want some confirmation
This is soooooo boring
imagine if he got a gold play button for teaching
Ily so much, you are the reason im not dropping biology
This was very helpful although I didn't pay much attention sorry teacher of you see this 🙂
God this video was completely useless to me
Nobody cares
who miss school
haha so my teacher's name is Mrs. Anderson, so everytime we watch one of your videos for school she says "We're watching Mr. Anderson's video, no not my husband." Now typing it I realize it's not that funny but it makes me laugh every time it happens because I'm super lame with low standards for humor so I thought I'd share for those like me lol
this sucks sorry but can you please not attract my teacher
Science time! I am excited!
At the end it says that if it was help ful it really wasnt
2021 anyone
I lost track a minute into the video
1:35 for complete chart
vamos por la 30 mr anderson
Thanks
MONOTONE ALERT
Who's here because of the cornia
this is too easy why aren't there harder videos
whos watching this in 2020 for school
Could someone write down the questions he asked cause i didn't get any of them
too fast. slow down partner. thanks
0:12
Can anyone tell which is the most efficient pyramid in terms of energy at 7:01
Nice t9 know
when i bored from my teacher i came to youtube
Nice work, I understood everything
your face is so distracting i wish i could turn it off
no
hey fellow bozeite
Wait i have a question. So we have the 10 percent law by leinderman…so as there is a 10% loss of energy along the trophic level…so vegeterians more energy efficient than non vegeterians ? So is it better to be a vegeterian ?
Ur a poopy head
Very helpful
Yeoo I have a science test on this tmrw so this helped😂
for ayone at k12 who needs the times for the questions here u go. 0:20 , 0:51
1:03 2:19 3:13 3:36 4:53 5:23 5:43 6:31 . hope this helps 🙂
Sorry but you talk to fast plz slow down for me plz, thx
Oh yes
i love Adriana
I love Hector
Sub to keipert labs
Thank you really much for everything you teach! You are so good 😊
Best voice ever
Thanks for this video super
