Why do natural polymers not pose as much of an issue in landfills as synthetic polymers? Natural polymers are cheap to recycle, and synthetic polymers are expensive to recycle.
Natural polymers are expensive to recycle, and synthetic polymers are cheap to recycle.
Natural polymers are not biodegradable, and synthetic polymers are biodegradable.
O Natural polymers are biodegradable, and synthetic polymers are not biodegradable.

Most polymers, including poly(ethene) and poly(propene) are not biodegradable . This means that microorganisms cannot break them down, so they: cause a litter problem if disposed of carelessly. last for many years in landfill sites.

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.
