How does vegetation adapt to climate of rainforest?

Answer 1

There are over 1000 species of trees which must compete with each other to reach the sunlight. The tallest trees (the emergents) can grow up to 50m in height. Their need to grow tall results in a tendency to straight trunks and few branches. The largest trees are anchored to the ground by buttress roots which the trees need as support because the soil is quite shallow in a rain forest and cannot support a deep root system. The main tree or canopy layer is typically 35-40m high and provides a dense unbroken cover. Lianas, which are vine-like plants, climb around the trees to reach the sunlight. The canopy receives most of the heavy rainfall so the leaves have adapted with drip tips that allow the water to run off the leaves. It is very dark under the main canopy and plants growing here had to adapt to the lack of light, with the result that large frond-like leaves are common. There is very little vegetation at ground level due to the lack of sunlight: as little as 1% of the sun reaches the forest floor. Only bacteria and fungi thrive here to rapidly rot the fallen leaves. However, near rivers or clearings where sunlight can penetrate, a dense undergrowth of ferns and shrubs develop.

Answer 2

the vegetation adapts to the equatorial climate by having trees with broad leaves to maximize the rate of transpiration which is a positive effect because in this region rain falls through out the year,the leaves also have thin surface area to allow gaseous exchange during respiration and photosythesis.Trees there have buttress roots for support the trees also have thin barks to maximize transpiration .climbers which are known as the liana are also common in the area because they require less sunlight .

Answer 3

this happens because the weather varies much in the Midwest or east of the world much more than any other place
