If a rock disintegrates by chemical weathering into small grains of similar composition, would this be considered reproduction?

No

Explanation:

No, because reproduction is a biological process by which the parents give rise to new individual which are termed as offspring produced from parents.

The reproduction is a character of living beings. It cannot take place in non living things.

Rock can be fragmented into smaller particles which is caused due to mechanical or chemical weathering.

hence, rock is not a living component so weathering cannot be considered as reproduction.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
