Recall that photosynthesis consists of two sets of chemical reactions. Which of these describes the energy conversion: that occur during the light-independent reactions?
light energy chemical energy
chemical energy › chemical energy
chemical energy > mechanical energy
mechanical energy > mechanical energy
The correct answer is: chemical energy>chemical energy (b)

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.
