Ecology Review: Food Chains & Webs, Relationships, Nitrogen & Carbon Cycles, Effects on Biodiversity

Join the Amoeba Sisters in this longer review video as they review ecology topics (see topics in table of contents by expanding description ⬇️ ). Topics include food chains, food webs, how energy flows through trophic levels (including the 10% rule), ecological relationships (including parasitism, mutualism, and commensalism), nitrogen and carbon cycles, and examples of how human activity can negatively impact biodiversity (examples include destruction of habitats, invasive species, overharvesting, and greenhouse gas emissions). The video concludes mentioning human efforts that can support and protect biodiversity. Eight questions are asked and answered in this video which can be skipped to in the table of contents.

Remember how we said that relationships determined to be 'commensalism' could change, based on various factors? For example: what if the "barnacles on a whale" example could have factors that could harm or help the whale? Check these out!

Fun fact: Birds are also seed spreaders as the seeds are dropped in their fecal matter. In fact, some trees rely on this as a form of reproduction. So losing a bird species could cause an ecological collapse.

Anyone else watching this before finals

I always look up Amoeba Sisters when I don't understand a topic taught in one of my courses. The Amoeba Sisters are very talented educators!

My high school biology teacher was a wonderful woman, and she used to play Amoeba Sisters all the time! Just looking them up randomly gives me such nostalgia ❤

[Bionium]

We are going to learn about this in January when schools reopen. Thanks amoeba sisters. Hopefully, this video will give me an advantage over the others in my class. Actually, this video broke down the topic in my biology textbook making it easier to grasp.

This saved me and my friend from failing our Bio 1 EOC
We love you Amoeba Sisters ❤

[AlejandroSerrano-ws]

Really good video, thanks, Amoeba Sisters. Even though this is like a remake from a video from 9 years ago, it is really good.

[Trash_boat_]

Thank you for the simple explanation. I used to watch your videos on my iPad and I was able to understand the stuff you said and I still understand the stuff.

Animation ❤
Explanation ❤
Understanding ❤❤❤❤❤❤

Thank you for breaking down it to be easier to digest! This channel is a staple in my study session for biology 💗

[NITHYALAKKSHMIKAKUMARADEVANMoe]

Its so easy to understand. THANK YOU AMOEBA SISTERS!🥰🥰🥰🥰🩷🩷

[redheadredemption]

The best explanations and examples. Can't wait to get the book and teach using it!

[JessicaAnne-vm]

Excellent ecology review! So thorough and helpful for understanding these concepts.

[Bhanshika-uo]

MIDNIGHT W ECOLOGY!? YOU MADE IT LIT ✨

[InesLassoued-rb]

Woohoo! I actually learned so much new and I can't wait to check out the recommended information, thank you as always 😊😻

[magicalmuffin]

I love your work and would really appreciate a video on neurobiology- action potential etc. 💞

[ufw_Allisa]

Hey I'm requesting for the osmoregulation in amoeba 😢😢 And also thank you for everything @AMOEBA SISTERS ❤🎉

[ChloeHarris-tv]

Fantastic review! So helpful for ecology.

[leveluptotalent]

Sister's you got a new subscriber ❤

I saw these all the time for science classes. Just coming back to see what they’re up to.
