Is it easy or difficult to identify specimens using the artificial classification of organisms? And why? Thanks!

difficult because you have to figure out if it is an animal protist or a plant protist ect and then find out what specimen type protist it is

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.
