Hypertonic is when the solution has a high concentration (high osmolarity), hypotonic is when the solution has a low concentration (low osmolarity) and isotonic is when the conditions are equal (same osmolarity). When in an hypotonic environment, a cell will take in water, causing it to swell
Plants convert carbon into oxygen and chemical energy so without carbon they wouldn't have food/energy so they wouldn't be able to live
Adaptation is a phenomenon that is about adjusting certain features to environmental conditions. Ie. birds are adapted to flight as they possess wings, very efficient lungs etc. or tropical plants are adapted to high temperature and humidity as they modified their photosynthesis process. but if some creature is adapted to the specific habitat or conditions, it is hard for it to manage in another habitat/different conditions. ie. birds are fast in the air but on the ground they are quite weak and prone to predators' attacks.
