AP BIOLOGY

Detailed explanation-1: -Trees are mostly broadleaf tree species including oaks (Quercus), hickories (Carya), maples (Acer), and beeches (Fagus), and commonly a diverse community of multiple strata of understory trees and shrubs, perennial herbs, and mosses.

Detailed explanation-2: -Oaks, beeches, birches, chestnuts, aspens, elms, maples, and basswoods (or lindens) are the dominant trees in mid-latitude deciduous forests. They vary in shape and height and form dense growths that admit relatively little light through the leafy canopy.

Detailed explanation-3: -The main trees found in these forests in North America and Eurasia include fir, oak, ash, maple, birch, beech, poplar, elm and pine. Other plant species may include magnolia, prunus, holly, and rhododendron.

Detailed explanation-4: -Ash, beech, and oak trees are found in temperate deciduous forests.

Detailed explanation-5: -Temperate evergreen forests Vegetation includes coniferous-evergreen tree species that produce cones and needles, dominated by spruce (Picea), pine (Pinus), fir (Abies), and hemlock (Tsuga) species, and the trees retain at least some of their needles year-round.
