Which Factors Exert the Greatest Influence over Terrestrial Biome?

What is a Biome? What Factors affect the Terrestrial Biome? What are the Biotic and Abiotic Factors?

A terrestrial biome refers to a region of land with a comparable climate and corresponding populations of plants and animals. If there are many biomes, they can generally be identified by their vegetation, such as trees, shrubs, and grasses. There are grasslands, woods, deserts, and tundra in a terrestrial biome. Let us see which factors exert the greatest influence over terrestrial biome and how some abiotic factors exert the greatest influence over terrestrial biome. Also, which biomes feature distinct wet and dry seasons will be discussed here in detail.

1. Which Factors exert the Greatest Influence over Terrestrial Biome?

There are 2 factors that strain the terrestrial biomes: 

  • Temperature: It prepares the type of vegetation from forest to grass as it gives the ample amount of sunlight that is needed for plant growth.
  • Rainfall: Rainfall helps in defining the type of animals and the vegetation which is seen in these biomes.

2. Which Abiotic Factors exert the Greatest Influence over Terrestrial Biome?

Terrestrial ecosystems are diverse as they are grouped into large categories called biomes. Terrestrial biomes are influenced by abiotic factors such as temperatures and precipitation. (See Which Tree Gives Oxygen?)

3. Which Biomes feature Distinct Wet and Dry Seasons?

The dry forest has both rainy and dry seasons. Its soil is rich in nutrients with a warm temperature. A lot of animals can adapt to the dry season’s survival, just like those in the savanna. Some animals in this biome are inactive during the dry season, and other animals migrate in search of water. Also, check out how many biomes are there in Africa?

4. What are the Types of Terrestrial Biomes?

The important terrestrial biomes are divided into small ecosystems. It is said that biomes are dependent on temperature and precipitation.

  • Forest Biomes: Forest biomes are of three types which are tropical, temperate, and taiga or boreal forest. The warm and wet tropical forests are called rainforests. The dry and cool conditions form deciduous forests in mid-range temperatures.
  • Grasslands: Grasslands are on land which does not have trees but has only grasses. It includes temperate and tropical regions.
  • Desert Biomes: These biomes are in dry regions, and they do not have any vegetation. They can be adapted to influence the precipitation of dry climate with less or no rainfall. They see hot days and cold nights.
  • Tundras: A tundra is completely covered with snow all over the year. It is called permafrost. The short herbs or shrubs grow only during the summers. They are only in the polar regions. 

5. What is an Ocean Biome?

The marine biome or ocean biome is the biggest biome in the world. It covers 70% of the earth. They include five oceans and they are Pacific, Atlantic, Indian, Arctic, and the Southern Ocean. Marine regions are very salty. The ocean is further divided into three vertical zones. The top layer is called the euphotic zone, the second layer is called the disphotic zone and the bottom layer is called the aphotic zone. Also, check out what plants live in the Ocean?

6. What is the Difference Between Terrestrial and Marine Ecosystems?

  • Terrestrial Ecosystem: Terrestrial biomes covers the inhabitants of the land surface which are impacted by fresh water. The organisms here live on land. The different kinds of terrestrial ecosystems are grasslands, deserts, and tundra.
  • Marine Biome: Marine ecosystems are living organisms that live in marine regions such as seas and oceans such as coral reefs and estuaries. These biomes cover 70% of the earth’s surface. The different types of aquatic ecosystems are fresh water and marine water. 

7. What are the Biotic and Abiotic factors for the Ecosystem?

The biotic and abiotic factors include all living and non-living organisms. They form a part of an ecosystem.

  • Biotic Factors: Biotic factors are the living organisms and constitute interactions between organisms like diseases, predation, parasitism, and competition with other species. They come under producers, consumers, and decomposers.
  • Abiotic Factors: The abiotic factors are the non-living components of the ecosystem which include chemical and physical factors. These could be sunlight, water, temperature, wind, and nutrients. Abiotic factors help living organisms to eat, grow and reproduce, such as temperature, climate, oxygen, water, etc.

A biome is a collection of various ecosystems that define a bigger population and area that is influenced by climatic patterns across time. There are two biomes, aquatic and terrestrial. This was the fundamental concept for the biomes in the ecosystems. I hope now you are clear about which factors exert the greatest influence over terrestrial biome.
