What does it mean for an organism to reproduce

Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parents". The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar or identical copy of itself.

Explanation:

Or: Why do living organisms reproduce?

Reproduction is the process by which new organisms (offsprings) are generated. A living organism does not need reproduction to survive, but as a species, they need that for continuity and to ensure that they are not extinct. They will be extinct. This means reproduction is essential for the survival of all species.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
