The Joys of Symbiosis










In nature, there are the "Jeff Bezoses" (the exploitative bosses), but there are also the critters who help others. Well, they help themselves in the process, so they are influenced by positive interactions. This means that either both organisms benefit, or just one. These interactions are the best - neither species is harmed and the animal kingdom can finally live in harmony. These engagements are either mutualism or commensalism and can affect the mix of species found in natural communities. 

Mutualism is the best interaction on the list; it means that both groups benefit from each other. Even in our own bodies, there are trillions of bacteria swimming around in our guts that help break down the juicy hamburger that we ate the night before. They stop us from getting super bloated and they get some much-needed nutrients. Bees land on flowers to drink sweet nectar but also inadvertently pollinate other blossoms in the process, benefiting themselves, but also keeping vital plants alive. Also, in the coral reefs, teeny algae live in coral, doing the process of photosynthesis (turning sunlight into sugar), keeping the coral alive (and giving it some pretty colors). But the algae also get a great place to live, so they benefit too! Some species (like the bees) evolved together, so removing one species from the other would result in the entire ecosystem going haywire, and Earth would turn into a mess, to say the least. However, some organisms can survive without each other - they are just worse off. 








Commensalism isn't as good as mutualism, but still, no one gets harmed. Commensalism is an interaction that benefits one species, but neither harms nor hurts the other one. This is super common in nature as well.

    I like how you connected symbiosis to our own human lives, because I feel like that is something we do not usually think about in our everyday life. It shows the whole process and life of how plants and animals interact with each other.

  2. The way you rewrote this bio passage was so fun to read! Your allusion to Jeff Bezos was really funny, and it helped establish a connection of some sort to the reader!

The Best Sapphic Artists (in my professional opinion)

Since we read "The Three Girls" this week, a very queer-coded piece, I made a list of my favorite sapphic artists: 5) Chappell Roan It seems impossible to compile a list of sapphic artists without including Chappell Roan. After her viral Coachella performance in April this year and her subsequent release of "Good Luck, Babe!" Chappell seems to have come out of nowhere. She is known for her love of drag and won Best New Artist at the VMAs. In some ways, she reminds me of the Marilyn Monroe we studied in "The Three Girls," especially in her desire to escape fame in some moments. However, she is also the opposite, incredibly vocal about her queer identity in every aspect of her life. I can't list her as my favorite, simply because I have not listened to her music enough, especially because she is so new to the spotlight. However, I absolutely love her unapologetic nature and can't wait to see what she does next! 4) LYVIA LYVIA is definitely the smalle...

The Average High School Experience (...right?)

My eyes dilated at the paper in front of me. I tried to control my breathing as I felt myself hyper-focusing on the crinkle at the top of the page. This is an imminent disaster. Why did I let him pass the paper to me? I should’ve just gotten it myself. There’s something so beautiful about a flat, perfect sheet of paper - why would anyone want to ruin it? Honestly, the assignment is barely worth doing if the paper is wrinkled. I attempt to refocus on the teacher’s lecture (something about poetry?) but there’s no use. The crease controls me.

Make Sleeping Cool Again

I still can't begin to understand how people manage to function off of 2-3 hours of sleep every night. And yet, everyone seems to be doing it? There's no doubt that we've turned it into some crazy competition. I'm already prepared to walk in tomorrow and hear the following conversation: "oh my godddddd. i literally stayed up until midnight to finish that blog post." "that means you basically got 6 hours of sleep. ugh you're so luckyyyyy. i stayed up till 3." So, not only are we invalidating others' problems, but we are also creating a culture that encourages others to make unhealthy choices for bragging rights. It's not the only thing we do it for either: "you wrote your ap seminar paper three days before it was due? i did mine the literal day it was due." "i can't believe you drive 50 in a 45. like you gotta drive 65 at least!" This isn't to say that I'm not guilty of the exact same things, but I'm sta...
