AP BIOLOGY

Detailed explanation-1: -The biome that would contain the most trees is the tropical rainforest. The tropical rainforest is a hot, humid biome that receives ample amounts of rain all year round. The tropical rainforest is a hot spot for biodiversity and large amount of species live in this biome that live nowhere else on Earth.

Detailed explanation-2: -Forests are dominated by trees, and cover about one-third of the Earth. Forests contain much of the world’s terrestrial biodiversity, including insects, birds, and mammals. The three major forest biomes are temperate forests, tropical forests, and boreal forests (also known as the taiga).

Detailed explanation-3: -Taigas are thick forests. Coniferous trees, such as spruce, pine, and fir, are common. Coniferous trees have needles instead of broad leaves, and their seeds grow inside protective, woody cones. While deciduous trees of temperate forests lose their leaves in winter, conifers never lose their needles.

Detailed explanation-4: -The taiga or boreal forest has been called the world’s largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States.

Detailed explanation-5: -taiga, also called boreal forest, biome (major life zone) of vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in northern circumpolar forested regions characterized by long winters and moderate to high annual precipitation.
