1) In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen. The plants use the sugar for food—food that we use, too, when we eat plants or animals that have eaten plants — and they release the oxygen into the atmosphere.
2) · Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases .In short, the CO2 levels decrease.
Answer:
A climax community
Explanation:
A climax community is a relatively stable community in which the component species are in equilibrium with one another.
Ecological succession involves a gradual change of the species composition structure of a community over a period of time.
<em>Depending on the initial state of a community, the species composition keeps changing from pioneer species of a completely new habitat in primary succession through secondary succession and, in the absence of disturbance, to a stable community which is referred to as a climax community.</em>
It actually says about the theory of evolution !!! as in what sequence they comes and become extinct !!! So B
