Detailed explanation-1: -Grassland biomes occur primarily in the interiors of continents (Figure 4) and are characterized by large seasonal temperature variations, with hot summers and cold winters (Figure 8).

Detailed explanation-2: -The deciduous forest is characterized by trees that lose their leaves at the end of each growing season.

Detailed explanation-3: -Chaparral, or Mediterranean Forests, and shrub is a temperate biome, characterized by hot-dry summers and mild and rainy winters. Nearly all of the rainfall occurs in the winter and spring rainy season. To picture the chaparral biome, you don’t have to stretch your imagination as far as you might think.

Detailed explanation-4: -Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome.
