How did the ice age affect plants?

During the ice ages, carbon dioxide levels drop by as much as 50 percent, causing the majority of plants, which require high levels of carbon dioxide (known as C3 plants) to decline. Some plants, known as C4 plants, especially grasses, grow well under low carbon dioxide conditions.

What ended Ice Age?

When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends. But there are many other factors.
