If both sides are loose then you do have a possibility of swallowing it, although not necessarily in your sleep. Just be careful when you wake up. Also, if it's loose on one side it won't fall.
Unicellular organisms or single celled organisms that are made up only of one cell. Hence the name.
Unicellular organisms are further divided into Prokaryotic and Eukaryotic organisms
Examples of prokaryotic organisms are bacteria and Eukaryotic are protozoa and unicellular algae, however many eukaryotes are multi cellular as well.
These organisms have to carry out life sustaining metabolic processes for their survival.
These processes are metabolism, homeostasis and reproduction. Metabolism is important as it involves conversion of food into energy for cellular processes. Homeostasis for maintaining a constant internal physical and chemical conditions and reproduction is by cell division.
Multi cellular organisms as the name says unlike unicellular organisms consists of more than one cells.
Examples of multi cellular organisms are animals, land plants etc.,
Metabolic process in multi cellular organisms is a broad category of processes happening for these organisms which involves chemical reactions and pathways that happen at organismal state, transporting substances between the cells.
This may not be the best answer but yeah: maybe we could restore the life by planting things and watering stuff. We could bring back shelters for the wild life. We will give it time to re-grow?
