Autotrophs and Heterotrophs

Curious about modes of nutrition? Join the Amoeba Sisters in learning about autotrophs and heterotrophs. Video explains these terms as well as how their carbon source differs. Photoautotrophs, photoheterotrophs, chemoautotrophs, and chemoheterotrophs, and their energy sources, are also discussed!

I would die for the amoeba sisters

[@lograystudios]

wait a second...if organic means carbon-based, how come carbon dioxide is inorganic? Also, great video! I would appreciate it if you start a series where you go through short videos and lengthen them to give more detail, while still offering the short videos if people just want a summery.

Hello, just wanted to say your videos help out a lot. when the textbook or other sources can be hard to understand, your videos clear up a a lot! so thank you!

[@richeldalapera8119]

Hey guys, I just found out that carbon dioxide (CO2) is "organic", because I have read that organic matter contains one or more carbon atoms, and that inorganic matter doesn't. Can you please change it if I'm correct, or correct me instead if I'm wrong?

[@AmoebaSisters]

So you bring up something that we had learned could be a topic all in itself! Some definitions will say any substance with carbon is organic, whereas others (like our cited sources) *generally* require both carbon and hydrogen meaning some carbon containing substances (such as carbon dioxide) would be inorganic. However, even that definition has exceptions such as carbon tetrachloride which is generally considered organic but has no hydrogen. Long story short, there is a lot of debate about these terms---and it seems most of the definitions have exceptions. One example is just searching for "is carbon dioxide organic or inorganic" which will pull up all kinds of different justifications. We actually have the topic of "organic vs. inorganic substances" on a potential future video topic poll, because we think it'd make a great exploration.

[@beatayacura6548]

[@ratkjng]

you said that plants are “generally” heterotrophs, so do you know of any animals that are actually autotrophs? if you do it would mean a lot if you could share, thanks ^w^

[@richeldalapera8119]

No, every animal, no matter what they differ from each other, is a heterothroph, as long as they consume organic matter, when she described them "generally heterothrops", she meant that, they are often described as heterothrops when trying to describe an animal. I hope this helps!
