I love this episode, it's my favorite one, but I think it would be a tough one for a first-timer.

So is it safe to say that if algae is present in a body of water, then you can expect the overall effect to be a net decrease in oxygen?

So does the algae itself consume oxygen (aerobic respiration?), or produce oxygen (photosynthesis?) in order to survive? Sorry, I study inorganic geochemistry but don't know much of anything about biology or botany.
Is there any difference between green algae and orange algae? I monitor water quality on a few streams, and the stream with the lowest dissolved oxygen (~30%) has both green and orange algae present, while the other streams have only green algae and have DO of 70-90%.
Also, are there any other plants that have a significant matting effect that dampens oxygen dissolution? Like a pond full of lily pads?

Don't worry, when winter rolls around, the gorillas simply freeze to death.

Reply to comment by elevenblade in when a limb gets amputated, how do they stop the flow of blood? by EnchantedCatto
Fascinating. I guess this answers a question I've had for a long time about how amputation works. I always assumed that during, for example, a leg amputation, the arterial system was like a 1-way highway for blood that went around your body in a circle, and into your leg and back out (with various exits and off-ramps for blood to go to your tissue), and you would have to connect the two halves of the pipe system if the connection was severed. But now it seems obvious that there is no "back out", or at least not a "back out" artery. It goes from the arteries to your tissue, and then it goes out through veins, right?

The inanimate carbon rod is apparently the thing that gets stuck in Homer's shirt during the title sequence.

What about making orange juice by smooshing the orange against your forehead?
