Tropical rainforests belong to a tropical wet climate group. Due to this climate, plants and animals thrive. Scientists estimate that more than half of all the world’s animal and plant species live in these forests. In fact, they produce more than 40% of the world’s oxygen. 70% of the plants in the rainforest are trees. Rainforest plants live in a warm humid environment which allows an enormous variation.
Evolution of plants has taken place a lot in these places. Plants compete for sunlight and food. They live on the branches of other plants and even strangle large plants for survival.
