The Pantanal soil is mainly sandy and clayey, this factor associated with the low slope and the many rivers of this region contribute to the Pantanal flooding. That is, it is moist most of the year and is full of animals such as alligators, beavers and various types of fish. In short, a wetland is a wetland, so we can say that the Bear Creek marsh is a wetland.
The first rains fall on a porous soil and are easily absorbed, with moistening of the earth various plant species sprout and the plain becomes green. In a few days the soil can no longer absorb the water that accumulates in the lower areas. The level of rivers and lagoons increases causing floods and the Pantanal becomes a huge flood. During drought, the water is restricted to riverbeds, ponds and wetlands.
The fish might start to die, and it will take a few generations of fish to be born before they have adapted to the chemicals in the water. If the water gets better after that, they will start to die again because they are not buoy for the environment and the whole or esa would start again.
All the water that is on earth today is the water that has been on the planet. Freshwater is a million years old. The same water is flowing in a continuous loop in the form of falling as rain and snow from the clouds to the earth’s surface. Running in rivers and ponds. This is due to the water cycle. The cycle where the water evaporates in the atmosphere and is from the atmosphere and then cloud loses the water as rain or snow.
