The meaning of the word mosaic that I am getting on Goolge is
First meaning is
a picture or pattern produced by arranging together small colored pieces of hard material, such as stone, tile, or glass
and the second meaning is
an individual (especially an animal) composed of cells of two genetically different types
I need to understand the meaning of the words - mosaic cropland, mosaic grassland, mosaic vegetation. But I am not able to see what does these words can mean if I use the above-mentioned meaning of mosaic. So, can someone please explain to me the meaning of mosaic in the context of given three words?
