Mosttrees are broad-leaved, hardwood evergreens.Sunlight is plentiful up here. Animals found areeagles, monkeys, bats and butterflies.Canopy layer forms a roof over the tworemaining layers. Most trees have smooth,oval leaves that come to a point. It forms a verydense layer. Food is abundant for animalsincluding snakes, toucans and tree frogsLittle sunshine reaches here so the plants haveto grow larger leaves to reach the sunlight. Theplants in this area seldom grow to 12 feet. Manyanimals live here including jaguars, red-eyedtree frogs and leopards and many insects.It's very dark here and so no plants grow here,Things begin to decay very quickly. A leaf thatmight take one year to decompose in a regularclimate will disappear in 6 weeks. Giantanteaters live in this layer. 7. AA DDeelliiccaattee EEccoossyysstteemm1. Rainfall is absorbed by the treesand pulled up to the canopy where itevaporates into the air.2. Trees and plants receive most oftheir nutrients from decaying matter(fallen leaves and organic debris).3. Plants and trees hold down thetopsoil and keep it from washingaway in heavy rains.4. When the land is cleared and cropsare planted, the soil doesn't stayfertile for long without the nutrientsfrom the decaying matter.5. Once the foliage is removed, heavyrains wash away the topsoil. 8.
