Explanation:
The alternation of generations is an important concept in the evolution of plants. All land plants have alternation of generations. In mosses and their relatives (Bryophytes), the haploid gametophyte is the dominant generation, and the diploid sporophytes are sporangium-bearing stalks growing from the gametophytes.
The correct answer is photosynthesis!
In fact, photosynthesis has the opposite effect: of reducing the among of carbon dioxide: it uses this gas and releases oxygen!
All the other options release Carbon dioxide, for example forest fires are a really big contributor to the amount of Carbon dioxide in the atmosphere.
