Detailed explanation-1: -Answer. Cinchona trees are mainly found in Tropical Evergreen Forest.

Detailed explanation-2: -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-3: -The taiga is characterized predominantly by a limited number of conifer species-i.e., pine (Pinus), spruce (Picea), larch (Larix), fir (Abies)-and to a lesser degree by some deciduous genera such as birch (Betula) and poplar (Populus). These trees reach the highest latitudes of any trees on Earth.

Detailed explanation-4: -While both the tundra and the taiga have lichens and mosses, the tundra has a greater diversity of grasses and wildflowers than the taiga. The taiga soil is highly acidic and low in nitrogen, making growth difficult for plants that are not adapted to the climate.
