Arachnids live anywhere they can find food. They live in grass fields and wet swamps. They live in hot, sandy deserts and cool, dark caves. They live in tropical rainforests and on rocky mountaintops. Arachnids like mites and ticks live in the fur of animals.
Arachnids often eat other invertebrates. Arachnids eat other arachnids, insects, small rodents, and even some small birds. Mites and ticks however feed off the blood and tissue of living animals, even humans. Other mites eat from liquified plants, fungus, and other organic materials.
I'm not sure if this is correct, but I believe it would be that plants need carbon dioxide (plants are living) plants need carbon dioxide to produce oxygen for humans to breathe in, not totally sure if this is correct like I said but I hope I kind of helped. :)

Thus, the solution inside the beaker is an hypertonic solution, that is why it deflated the dialysis bag.
