Which of the following is/are features of tropical evergreen forest?1...
- Tropical evergreen forests are found in warm and humid areas with an annual precipitation of over 200 cm and mean annual temperature above 22 degree C.
- Tropical evergreen forests are well stratified, with layers closer to the ground and are covered with shrubs and creepers, with short structured trees followed by a tall variety of trees. In these forests, trees reach great heights up to 60 m or above. There is no definite time for trees to shed their leaves, flowering and fruition. As such these forests appear green all the year round.

Which of the following is/are features of tropical evergreen forest?1...
The correct answer is option B: 1 and 2 only.
Tropical evergreen forests are characterized by their high levels of precipitation, the absence of a definite time for trees to flower, and the presence of stratification.
1. Annual precipitation of over 200 cm:
Tropical evergreen forests receive high amounts of rainfall throughout the year, with an annual precipitation of over 200 cm. This high level of rainfall creates a moist and humid environment, which is ideal for the growth and survival of evergreen trees.
2. No definite time for trees to flower:
Unlike deciduous forests, where trees shed their leaves in response to seasonal changes, tropical evergreen forests have trees that do not have a definite time for flowering. This is because these forests do not experience distinct seasons like spring or autumn. Instead, they have a relatively constant climate throughout the year, with little variation in temperature and rainfall. As a result, trees in tropical evergreen forests can flower and produce fruits at any time of the year.
3. Absence of stratification:
Contrary to the statement, tropical evergreen forests do exhibit stratification. Stratification refers to the vertical arrangement of vegetation in different layers or zones. In tropical evergreen forests, there are distinct layers or strata of vegetation. The topmost layer, known as the canopy, consists of tall and closely spaced trees that form a continuous cover. Below the canopy, there is an understory layer composed of smaller trees, shrubs, and saplings. Finally, the forest floor is covered with a layer of leaf litter and herbaceous plants. This stratification allows for the efficient use of space and resources, as different species can occupy different layers and niches within the forest.
In conclusion, the features of tropical evergreen forests include annual precipitation of over 200 cm, no definite time for trees to flower, and the presence of stratification. Therefore, the correct answer is option B: 1 and 2 only.
