Known as the twilight zone, the mesopelagic zone meets the photic zone above and becomes very dark as depth increases. temperature decrease; pressure increases. because nutrients are limited here, some animals rise to the photic zone at night for food. many animals in this subzone can eat animals larger than themselves because they are equipped with large sharp teeth with expandable jaws and stomachs. another key physical feature of animals living in this zone is which has a variety of purposes, including predator deterrence, communication, and lures for prey. a) symbiosis b) transparency c) bioluminescence d) oversized scales

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
