The common way that a species is defined in biology is in terms of reproductive isolation. This means that all organisms that are similar enough to produce fertile offspring in nature.

Explanation:

Reproductive isolation can be described as the ability of organisms to live in a place but mate and reproduce with the organisms which are alike to produce fertile offsprings. The phenomenon of reproductive isolation allows organisms of a species to mate and produce fertile offsprings. The production of fertile offspring is very necessary for the continuation of a species on the Earth. Those organisms in a species which are better adapted to live in the environment are able to reproduce and produce fertile offspring.

"d.) carbon dioxide and hydrogen sulfide"

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
