@@yolandagonzalez4021 Thank you so much! This video actually does have Spanish subtitles (viewable if clicking the gear at the bottom right once the video starts and selecting Spanish), but we are definitely hoping we will get Spanish subtitles for all of our videos as some do not have them yet.

At first we were like “he’s treating us like little kids” but now we get excited every time he puts a video, and we laugh at the references. Thanks for existing.

Symbiosis: Interaction between two different organisms living in close physical association, typically to the advantage of both.
Mutualism: The doctrine that mutual dependence is necessary to social well-being.
Parasitism: The practice of living as a parasite in or on another organism.
Commensalism: An association between two organisms in which one benefits and the other derives neither benefit nor harm.

1:21 That Pokémon reference there is actually pretty appropriate because there’s actually a Pokémon evolutionary line (consisting of Trapinch, Vibrava, and Flygon) based off of the antlion (and they can really learn Sand Attack). I wonder if Petunia had that in mind when making that picture.

[@bluehoodie_gamer6867]

plus, sand attack is useful if you want to lower your enemies defense

The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. [beep] A single lap should be completed each time you hear this sound. [ding] Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, start.

Of course there is a use for sand attack! Lowering a pokemons accuarcy can be very helpful when your opponent has a move like fissure so that it can hit less likely because fissure is a OHK move. I am way to addicted to pokemon.

[@kevinwalters3191]

Although acacia trees and ants are a great example of mutualism, it is a bit more one-sided than a lot of people realize. See, the "free" nectar given to the ants actually comes with an enzyme which makes it so that they can ONLY get their sugar from the nectar, because unless a different food source has another particular enzyme (like the nectar does) which enables them to digest that sugar, they won't be able to eat it. P.S. for the nectar, the enzyme that helps them digest the sugar only works for that particular round of digestion. They just have to keep eating the nectar for that enzyme.
If I didn't explain that well, there is a video on the UA-cam channel "Scishow" that does.
Also, in addition to protecting the acacia trees from predation and competion, the ants also greatly reduce the amount of pathogens that colonize the tree due to the ants' symbiotic relationship with special bacteria on their exoskeleton.

[@jinkstacks4830]

I had a question that said a butterfly ate a specific plant and the butterfly benefited from the toxin it gave or something.
The answer they said was correct was commensalism, but I thought it would have been parasitism or predation before commensalism because the plant is being eaten?
