Answer» Correct Answer - Option 4 : tropical rain forest
The correct answer is tropical rain forest. - Tropical rain forest:
- The tropical rain forest is a forest with tall trees in a region of year-round high temperatures where an average of 50 to 260 inches of rain falls yearly.
- Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 34 °C or drops below 20 °C, average humidity is between 77 and 88%. Rainfall is often more than 100 inches a year. There is usually a brief season of less rain. Almost all rainforests lie near the equator.
- Many of the trees have straight trunks that don’t branch out.
- The majority of the trees have a smooth, thin bark because there is no need to protect them from water loss and freezing temperatures.
- It also makes it difficult for plant parasites to get a hold on the trunks.
- The bark of different species is so similar that it is difficult to identify a tree by its bark.
- Many trees can only be identified by their flowers.
- The fertility of topsoil in rainforest regions is very poor. Torrential downpours wash out most of the topsoil nutrients.
- The soil deteriorates rapidly with subsequent soil erosion and soil impoverishment.
- The equatorial vegetation comprises a multitude of evergreen trees that yield tropical hardwood, e.g. mahogany, ebony, dyewoods etc.
