about twenty however there is a great amount of variance in this as certain organisms use some that others do not. At most twenty-six.

Most elements are required by some living things, somewhere - there's worms on the sea-bed that synthesise their nutrients from minerals venting from the sea floor, archaea that consume arsenic for respiration, all kinds of weird things like that. In terms of humans, we're talking carbon, hydrogen, oxygen, calcium, phosphorous, magnesium, sodium, iron, at the least - and there may be a few I've missed off that list.
There are four elements-carbon , hydrogen , oxygen , nitrogen.
The six most abundant elements found in living things are oxygen, carbon, hydrogen, nitrogen, phosphorus, and calcium.
The most important are C, H, O, N, S, P, etc.
There are 25 elements in living matter.

yes although the number of cells in an organism may vary depending on whether it is a unicellular or multicellular organism.
A housefly has 12 chromosomes in a diploid. Every living organism on the planet has a chromosome number represented by a diploid number (2n).
Living cell organisms are alive and non-living organisms are dead. There are a number of different criteria for what it means to be living. For instance: metabolism, the ability to react to a stimuli, and so forth. If an organism does not exhibit any of these qualities, it can be concluded that the organism is not living. An example: a table is a non-living thing. A cat is a living thing. the important differences between living things need a suitable habitat that supplies their basic needs for oxygen,food,and water. and non living things don't need a suitable habitat that supplies their basice needs for oxygen,food,and water.

A population in a community means the specific kind of organism (plants and animals) living in a community (all the living things in an ecosystem)
The number of genes it has.
It is about half
There is no such number, depending on the organism the number of chromosomes varies from 1 to about 30,000,000!
DNA provides the information necessary to take a number of lifeless chemicals and turn them into a living system.

The destruction of natural resources in living organisms can have a negative effect on the ecosystem. destroying the environment where an organism lives can reduce the number of organisms in the area.
The reproductive cells of an organism each contribute half of the required genetic material to create the offspring. This means that each reproductive cell has 1n, while the organism has 2n chromosomes.

Anywhere from one to billions. Every organism is different, and most of the time it's impossible to know the exact number of cells. Also, the number of cells is not constant at all times for most organisms.
