All living creatures must get rid of body wastes, both solid and liquid.
Many animals do not have separate systems for disposing of these wastes as say, mammals do. Mammals (placental animals) have an advanced specialization.
Birds, reptiles, and amphibians make do with the one vent, the Cloaca. (Latin for sewer). In birds at least, this organ also embodies the sex functions.
It is difficult to imagine fish with a need for separation of liquid and solid wastes.
More primitive (my words) animals such as monotremes and maybe some kangaroo demonstrate traces of the early cloaccal development.
it allows us to urinate so that we can let others know that they are in our territory
All living things are made of cells. All living things require and use energy. All living things grow, develop, reproduce and repair themselves. All living things produce waste All living things respond and adapt to their environment. All living things have a life span.
Considering that plants are also living things we all need oxygen, so all living things breath.
All organisims are living because, they all have the same characteristics, we need to eat, sleep, have water, excreamate and urinate and that has (or can develop) the ability to act or function independently . Organisims are all mover the place, mammals,birds,reptiles,fungie,fish, plants anything with those characteristics. There are such things as bio organisims. bio organisims are things like rocks, shoes, desks, chairs who can not move independantly, eat, drink, sleep, excreamate or urinate and these objects are not organisims. Happy to help.
All living things are made of cells, all living things ether need or produce oxygen, all living things reproduce, all living things make and use energy, and all living things adapt to their enviorment.
All living things use energy
Carbon IS found in all living things.
cells are the basic unit of living things
