For me, it is Air pollution. Which the air we breathe in order to sustain life is being contaminated by pollutants and other chemical substances as well as hazardous substances.
Living Organisms
Living organisms
Both, but mostly chemical.
If you mean element-wise, living organisms contain mostly carbon, oxygen, hydrogen.
It will affect mostly mammals and sometimes birds.
There is pollution because organisms (mostly humans) need to get rid of waste and get around there environment. Example: Humans have cars to go places (Car = Pollution) Pollution by organisms other than man is usually not a problem, as other organisms have evolved over time to consume the pollutants returning it to a harmless form. But man is changing things faster than evolution can keep up with.
Acid rain. Which can be produced either by industrial pollution (mostly sulfuric acid from coal burning), internal combustion engine pollution (mostly nitric acid), or large scale volcanic eruptions (mostly sulfuric acid).
Water pollution mostly affects animals that live in the water and any other animal because they all drink water and the water is polluted. hope i helped :)
The predominant elements in living organisms are the four CHON elements; Carbon, Hydrogen, Oxygen and Nitrogen.
The ozone layer mostly absorbs the harmful ultraviolet radiations. These radiations are very harmful as they cause a no of problems in living organisms.
Mostly air pollution
Most of the known naturally occurring zinc is not found in living organisms, but rather in minerals.
