"carbon cycle
During photosynthesis, plants remove carbon from the air and store it as chemical compounds such as sugar, the carbon will be released back into the atmosphere through cellular respiration. Sometimes plants or animals with carbon trapped in their body will get buried before fully decaying; over millions of years the heat and pressure will turn them into fossil fuels containing carbon. This carbon is then released back into the atmosphere through combustion."

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
