Question

How do biomes change with altitude?

Answer 1

Hint: A biome is a large regional unit that is characterized by a major vegetation time. The biomes are associated with fauna found in the climatic zones. Moreover, the biome is the largest level of the biological organization.

Complete answer:
The variations in the temperature and annual precipitation account for the formation of the major biomes. Factors like rainfall, nature of the soil, temperature range, altitude, and latitude determine the nature and the extent of the biomes.
The biomes change with an increase in altitude because of the type of vegetation changes. This is because of the decrease in temperature. Based on the altitude the biomes can be classified as given below –
Tropical rain forest/Grassland/Desert – They are found in the equatorial and sub-equatorial region and grow on land which is at sea level. Tropical forests are rich in biodiversity and experience heavy rainfall. Grasslands are treeless biomes and possess only grass. Deserts have very sparse vegetation and experience a shortage of water.
Temperate deciduous forest – They are also known as a broadleaf forest. They occur at a slightly greater altitude than the mean sea level. They are usually found in the temperate zone. It consists of tall, deciduous trees with broad leaves.
Coniferous forest – They are also known as the Temperate needle-leaf forest or Taiga forest. They are found at mountains and higher altitudes or the cold temperate regions. They consist of very tall trees, known as the coniferous or evergreen trees. Their leaves are long needle-like.
Tundra forest – They are found at the highest altitude. Usually, they occur in the north Arctic tundra. They are the regions of permafrost where the sub-soil remains frozen. It has very scanty vegetation and trees are absent.

Note:
The ecology is concerned with the four levels of biological organization which are the organisms, populations, communities, and biomes. The organism is the basic unit of the study of ecology. It refers to a single individual living being. A group of individuals of the same species that live in a specific area forms the population. An assembly of several interactive and interdependent populations of different species forms the communities.
