Answer:
Because of the fertile plains of the Danube River.
Explanation:
Slovakia and Czechia (formerly the Czech Republic) despite being part of a single country until three decades ago, and being neighbors with very close ties, have developed differently and their economies have a lot of differences. One of the biggest differences is that Slovakia has a highly developed agricultural sector while Czechia's is very small and doesn't contribute much to the economy.
s The reason for this difference is geography. Slovakia has a relatively large and very fertile plain, with the Danube River being a big plus in it. This provides Slovakia with enough area and very good conditions so that it can have a prosperous agricultural sector. Czechia, on the other hand, is almost entirely covered with mountains and hills, and the little area of the handfull of valleys is mostly urbanized, thus the country doesn't have what it needs to develop the agricultural sector.
Similarities:
- Marine and freshwater ecosystems are water, covering almost 75 percent of the earth's surface.
-The most pervasive problem affecting both freshwater and marine ecosystems is pollution.
-The process of regulating the osmotic pressure on fluids inside an organism is essential to all freshwater and marine species.
Differences:
- Marine ecosystems are more diverse than freshwater ones.
- In marine or seawater, the salinity level, or the concentration of salt is greater, but freshwater is not totally void of it.
- Only 1% of the whole water body on the earth is freshwater, the other 99% is marine water.
Note- I couldn't come up with ones for estuaries, sorry.
