Terrestrial Ecosystem – Class 12 | Chapter – 14 | Biology Short Notes Series PDF

Terrestrial Ecosystem: A terrestrial ecosystem is an ecosystem that occurs on land and is characterized by terrestrial vegetation and animal species. Terrestrial ecosystems can be found in many different regions and climates, ranging from the hot and dry deserts to the cold and wet rainforests. Terrestrial ecosystems are important for the survival of many species and play a critical role in regulating the Earth’s climate and supporting human societies by providing a range of resources, including food, timber, and fuel.

Features of Terrestrial Ecosystem

Some of the key features of terrestrial ecosystems include:

  • Vegetation: The type of vegetation found in a terrestrial ecosystem depends on the climate and soil conditions of the region. In some areas, forests and woodlands are the dominant vegetation, while in others, grasslands, shrublands, and deserts are more common.
  • Soil: The type of soil found in a terrestrial ecosystem depends on the climate and vegetation of the region. Some areas have nutrient-rich soils that support a diverse range of plant life, while others have nutrient-poor soils that support only a limited range of plant species.
  • Climate: The climate of a terrestrial ecosystem can range from hot and dry to cold and wet, and can have a significant impact on the type of vegetation and animal species found in the ecosystem.
  • Animal life: The animal species found in a terrestrial ecosystem depend on the type of vegetation and the climate of the region. Some areas are home to large mammals, such as elephants, lions, and bears, while others are home to smaller animals, such as reptiles, birds, and insects.
  • Interactions between organisms: The interactions between different plant and animal species in a terrestrial ecosystem are complex and can have a significant impact on the ecosystem as a whole. For example, predator-prey relationships, mutualisms, and competition between species can all influence the structure and function of the ecosystem.

Types of Terrestrial Ecosystem

Some of the main types of terrestrial ecosystems include:

  • Deserts: Desert ecosystems are characterized by hot, dry climates and sparse vegetation. They are found in areas with low annual rainfall and high temperatures, such as the Sahara Desert and the Mojave Desert.
  • Grasslands: Grasslands are characterized by rolling prairies, grasses, and scattered trees. They are found in areas with moderate rainfall and temperatures, such as the Great Plains of North America and the savannas of Africa.
  • Temperate forests: Temperate forests are characterized by deciduous trees that lose their leaves in the fall, and are found in areas with moderate temperatures and rainfall, such as the northeastern United States and parts of Europe.
  • Tropical rainforests: Tropical rainforests are characterized by high temperatures and high rainfall, and are found in areas near the equator, such as the Amazon Basin and the Congo Basin. They are known for their high levels of biodiversity and rich plant and animal life.
  • Taiga (Boreal forests): Taiga, also known as boreal forests, are characterized by coniferous trees and long, cold winters. They are found in the northern latitudes, such as the region surrounding the Arctic Circle.
  • Tundra: Tundra ecosystems are characterized by harsh conditions and limited vegetation, and are found in the far northern regions of the world, surrounding the North Pole, and at high elevations in alpine regions.

Terrestrial Habitat Plants

A terrestrial habitat refers to an environment on land, and the plants that grow in this habitat must be able to adapt to the specific conditions found there. The types of plants found in terrestrial habitats are diverse and vary depending on factors such as climate, soil type, and water availability. Some common types of terrestrial habitat plants include:

  • Desert plants: These plants are adapted to grow in hot and dry environments, with features such as deep roots, small leaves, and the ability to store water. Examples include cacti, succulents, and mesquite trees.
  • Forest plants: These plants are found in areas with high rainfall and moderate temperatures, and are often tall and have large leaves. Examples include hardwood trees such as oak and maple, and shrubs such as rhododendrons.
  • Grassland plants: These plants are found in areas with moderate rainfall and moderate temperatures, and are typically shorter and have deeper roots to take advantage of water that may be deeper in the soil. Examples include grasses such as buffalo grass, and wildflowers such as sunflowers.
  • Alpine plants: These plants are found in high-elevation environments with harsh conditions, including low temperatures and high winds. They are typically small and hardy, with features such as dense fibers to resist the wind. Examples include alpine shrubs and wildflowers such as edelweiss.
  • Tundra plants: These plants are found in areas with extremely cold temperatures, limited rainfall, and low soil fertility. They are typically small and hardy, with features such as shallow roots to take advantage of the limited water available. Examples include mosses, lichens, and dwarf shrubs such as willow.

Terrestrial Habitat Animals

Terrestrial habitats are environments on land, and the animals that live in these habitats must be able to adapt to the specific conditions found there. The types of animals found in terrestrial habitats are diverse and vary depending on factors such as climate, vegetation, and food sources. Some common types of terrestrial habitat animals include:

  • Desert animals: These animals are adapted to survive in hot and dry environments, with features such as the ability to conserve water, burrow underground to escape heat, and hunt for food at night. Examples include reptiles such as rattlesnakes, birds such as roadrunners, and mammals such as kangaroo rats.
  • Forest animals: These animals are adapted to life in areas with high rainfall and moderate temperatures, and are often arboreal (tree-dwelling) or have strong, climbing abilities. Examples include primates such as monkeys and apes, birds such as parrots and woodpeckers, and mammals such as squirrels and bats.
  • Grassland animals: These animals are adapted to life in areas with moderate rainfall and moderate temperatures, and are often capable of running at high speeds to escape predators and hunt for food. Examples include ungulates such as bison and antelope, carnivores such as wolves and lions, and birds such as prairie chickens.
  • Alpine animals: These animals are adapted to life in high-elevation environments with harsh conditions, including low temperatures and high winds. They are often smaller and hardier, with features such as dense fur to resist the cold. Examples include mammals such as marmots and pikas, and birds such as ptarmigans.
  • Tundra animals: These animals are adapted to life in areas with extremely cold temperatures, limited rainfall, and low soil fertility. They are often small and hardy, with features such as the ability to store food for the long, harsh winter. Examples include mammals such as arctic foxes and reindeer, and birds such as snow buntings and rough-legged hawks.
