Ecosystems

047 - Ecosystems
Paul Andersen explains how ecosystems interact with biotic and abiotic factors. He explains and gives examples of food chains and food webs. He shows how limiting factors eventually leads to logistic growth. Real data from Yellowstone Park is used to show how populations interact. He ends the podcast by showing how human impacts can eventually lead to changes within an ecosystem.

[@kelseyrue4302]

Senior in college about to get my degree in biology and I’ve been watching your videos since my freshman year of high school! You are amazing mr. Anderson!

[@TimChaley]

Kelsey Rue hey I’m thinking of majoring in biology. If there was one thing you wish you knew before starting that major, what would it be? And what helped you achieve it? Plz and thanks

[@lemonlime07]

I am in 8th grade in India and learning this. I think our system is flawed lmao jk 😂
Also congratulations 🥳

[@nathanchen9181]

Paul Andersen, you are a god. Why can't you be everyone's biology teacher?

[@parasiticangel8330]

he is everyone's biology teacher

[@morpheus_circuit]

Blasphemy!

[@jsplicer9]

My bio teachers have the Bozeman t-shirts.

[@jelly_belly101_2]

nooooo 😭

[@sanatdas2011]

Thank you, Sir for sharing this videos with us. This was really very helpful. Thanks again.
- A Zoology student all the way from India.

[@DeviL-ll4ln]

Love from Canada

[@SnipeRespect]

I bet all his students get 5's on the AP exam

[@NormanYeung19]

I hope I do :S

[@starwarfan8342]

did you

[@420sadness]

i hope i do lol i had a summer assignment for AP bio and its to watch his videos and answer questions.

[@destinhayes7893]

Last Bozeman review sheet for the year babyyyyyyyyyyyyyyy!!!

[@sui_tea]

If you are forced to watch his videos, u r not a true fan of Paul Andersen therefore u dont deserve him.

[@chuckdelane7730]

You remind of Chef Alton Brown. from the Food Network.....You guys describe your profession with so much animation and character. Wish i had a teacher like you,.

[@turkeyboy-bz2cr]

lol why this guy talking about Yellowstone in Wyoming when Wyoming doesn’t even exist?

[@basil4047]

ik im really stupid but i though yellowstone was in california :|

[@jenwhite9335]

Had to watch this for homework. Lol

[@kamransalahuddin7457]

same lol

[@carolg118]

[@splodinatekabloominate846]

Say hi to my psychotic bio teacher everyone! She managed to leech all the fun out of this video

[@annasame7395]

so relatable

[@onesarcasticmexican]

Very helpful, thank you. For some reason, you explained it better than my textbook.

[@razasyed575]

Great Video!

[@schoolgirl499]

yep

[@jordaynelexidrasal3426]

What would happen if we let things run naturally?

[@bobimimihello]

what is abt ecosystem service? what s different ?? thanks alot

[@AlwaysLoudAA]

Hello Ms. Huisinga!

[@yrdedgrndma226]

My teacher is making me watch this :(

[@901Nash]

good video

[@dvitakapadia860]

hey guys, just wondering: for those who've taken the AP Biology exam; how important is Ecology in the exam? Like how many questions are about ecology?

[@loafusloaufusboboafus8971]

Not much.

[@mspacman94]

you da you da BEST!

[@Lolitsme77]

Why is it called 2nd level consumer, if they're on the 3rd level? I know they are the second set of consumers but the words "2nd level" and "3rd level" being thrown around confuses me .-.

[@splodinatekabloominate846]

Because the first level is not a consumer of other organisms; they are producers because they convert abiotic elements to usable energy

[@salohcin921]

The bio teacher has like a freakin crush on this guy. But the vids are helpful and the name "Mr Anderson" XD gotta love the matrix

[@DemonPride72]

On the human impacts slide you drew the arrow pointing the wrong way for the bear and the squirrel and im losing my mind over it.

[@SirBarington]

Was this created with Adobe Presenter?

[@ethanwilliams1910]

Who else was forced to watch this?

[@splodinatekabloominate846]

by a psychotic biology teacher *cough cough* mine

[@starwarfan8342]

Ethan Williams ikr bruh

[@Skyexotic0]

Me

[@foxheart303]

yeah highschool biology class

[@pinkcarrots5529]

oh god 14 minutes... i can't
i don't have the attention span

[@carrjeep7538]

Great video but that squirrel looked suspiciously like a chipmunk to me.

[@chriskimkim1]

What does bbecpo mean?

[@janarthanank5852]

Chris Kim it means biosphere, biome, ecosystem, community, population and organism(bbepco)

[@xiiixiiih.16]

That is scary

[@brodyzerafa428]

hi

[@nicolecervantes3145]

you are right lets respect the ecosystem and do not distrupts them because if we did that food chains would be out of balance and animals could be endangered. You see people just throw out their trash and when animals think it was food they would eat it and die. Also people build roads and homes in their environment and then when animals cross the road they'll get hit. Lets think before we do it. Thank You!:)

[@DanielR1-MIDI]

AP Bio anyone?

[@LilVioletBoi]

Bruh, we had to watch this to answer some stuff in Biology-

[@thebestpro1003]

[@kevinlam1828]

Roooooney give me 3

wsg

[@peterallison4464]

The entire world has less animals in it than yesterday and tomorrow less and this path will continue until ecological collapse then the world will be forced to take notice. This is the unromanticized reality. Covid 19 has accelerated this process as animals are a food resource and this will carry on until ecological collapse. No matter what we say and what we do this trajectory has carried and will carry on: as a species humans are just not intelligent enough to rectify this issue at the present time. Reality can be very different from are myopic expectations. Equalibram will be obtained regardless of human opinion and this my well not be to Human advantage as we see it.

[@ABrown-sn2xx]

"Basically"

[@MegaGullala]

He says that so much 😂

[@ABrown-sn2xx]

Right? 😂 I knew I wasn't alone. 😂
