Interpreting climatographs means reading how temperature and rainfall change through the year and linking that to what kinds of plants can thrive in a biome. A temperate grassland climate has distinct seasons with hot summers and cold winters, and a moderate amount of rainfall that mainly occurs during the growing season. In the graph you’d expect to see temperatures rise above freezing in the warm months and drop in winter, while rainfall increases in spring and summer but remains well below rainforest levels. That pattern favors grasses and a fire- or drought-tolerant ecosystem rather than dense forests, which is why this climatograph aligns with temperate grassland. By contrast, tropical rainforest would show warm temperatures year-round with high, steady rainfall; desert would show very low rainfall and wide temperature swings; tundra would be cold most of the year with low precipitation and a very short growing season.
