Explanation:

The rodents have a great variety in terms of their shapes, sizes and weights, there are small ones such as the pygmy mouse (Baiomys musculus), even giant animals such as the capybara (Hidrochaeris hydrochaeris), they can have short, silky fur like the silky bag mouse ( Perognathus flavus) or long and hirsute hair like thorns like the prehensile tropical porcupine pig (Coendu mexicanus).

Rodents are very important organisms within ecosystems as they provide various benefits, an example of this is that many rodents scratch the ground for the construction of their burrows, soil aeration and water infiltration, which promotes growth of the plants, as well as introducing organic matter to the subsoil making them more fertile.
