Explain how the absorption of water by roots photosynthesis take place. long answer .

photosynthesis is the process by which plants use sunlight to manufacture their food from carbon dioxide and water.

so the water the plants roots absorb from the soil is a necessity for photosynthesis

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.
