The tropical rainforests are also called evergreen forests as they remain green throughout the year...

Tropical rainforests are a type of forest that are characterized by high levels of rainfall and humidity throughout the year. These forests are found in tropical regions near the equator, where the climate is warm and wet. The correct answer to the question is option 'c) Tropical evergreen forest'.

Below is a detailed explanation of each option:

a) Temperate evergreen forest:
- These forests are found in regions with temperate climates, characterized by distinct seasons.
- They are usually found in areas with moderate rainfall and cooler temperatures compared to tropical regions.
- Trees in temperate evergreen forests retain their leaves throughout the year, providing a continuous green canopy.

b) Temperate deciduous forest:
- These forests are also found in regions with temperate climates.
- They experience four distinct seasons, including a cold winter and a warm summer.
- Deciduous trees in these forests shed their leaves during the winter to conserve energy and reduce water loss.

c) Tropical evergreen forest:
- Tropical evergreen forests, also known as tropical rainforests, are found in tropical regions near the equator.
- They receive high amounts of rainfall throughout the year, typically ranging from 80 to 400 inches per year.
- These forests are characterized by a dense, multi-layered canopy of trees, with a high biodiversity of plant and animal species.

d) Tropical deciduous forest:
- Tropical deciduous forests, also known as dry forests or monsoon forests, are found in tropical regions with distinct wet and dry seasons.
- These forests experience a period of heavy rainfall followed by a dry period, during which the trees shed their leaves to conserve water.
- They have a lower tree density compared to tropical rainforests.

In conclusion, tropical rainforests are known as tropical evergreen forests. These forests are characterized by high rainfall, high humidity, and a diverse range of plant and animal species. They are found in tropical regions near the equator.
