You ask some questions:
No...otherwise it would be considered living!
Y.Teddy bears do not come alive in the night, are not ALIVE. think about it, a teddy is stuffed with wool, it is only fur, it has no bones, guts, or limbs. it has butten or glass eyes. and if it did come alive it would probably kill you for stuffing it with cotten. Thanks :)
For example, without the Sun (nonliving) plants(living) couldnt't grow which in turn most consumers would die, then the things that eat the consumers would die, and so on. And without water (nonliving) nothing at all would survive. I even be here telling you this without water.
A waterfall is nonliving because water is not a living thing.
There is no such thing as a "non-living" cell. If you are referring to living things being produces by non-living sources that would be abiogenesis.
Some examples of living things that may appear to be nonliving include dormant seeds, non-moving plants, and hibernating animals. These organisms can exhibit characteristics of nonliving objects due to their lack of activity or apparent growth.
It is estimated that there are around 10^30 living cells on Earth, with the majority being microbial. Nonliving cells, such as those found in rocks and minerals, do not have a well-defined count but are significantly fewer in number compared to living cells.
I would assume that you would use displacement to determine volume when the object is extremely complicatedly shaped.
To determine if an object is charged, you can use a device called an electroscope.
glass is non-living, as it was never alive. if it was made of animal matter, then it would be classed as living, even if it was dead. Sand has never been alive, so it is non-living
A nonliving factor would be called an abiotic factor. A living factor would be called biotic
A life scientist may study nonliving things like lakes or rocks to better understand the environment in which living organisms exist. By studying the physical characteristics and chemical composition of these nonliving components, scientists can assess how they influence the growth, behavior, and distribution of living organisms in a given ecosystem.
