 | You are right in general speaking. However, the major difference between marshes and swamps in biology is whether they have trees. Actually, swamps have trees, but marshes usually don't and are dominated by grasses and other herbaceous plants. | |
|
| I didn't know that. | |

|
| Next question. In wetlands including marshes, water covers the ground for a long period. So what does that water bring to the herbaceous plants? | |
|
| That is an interesting question... You mean nutrients or something like that? | |
|

|
|
| Correct! Rivers carry rich soils to them. So marshes have rich biodiversity. Furthermore, the plants slow down the water streams and help the spread of the marsh! | |
|
| Oh, so they are called "marshes"! | |
