Ecosystem Zones 
distinct regions of the Earth that are characterized by specific environmental conditions and support unique communities of
plants, animals, and other organisms
...ecosystem zones include: Zone Description Tundra A cold and treeless biome found in the
Arctic and high mountain regions
...
Effects of Ice Melt on Tundras These changes can have cascading effects on the entire ecosystem, affecting the animals that rely on tundra
plants for food and shelter
...Many species of animals depend on tundra habitats for survival, including iconic species such as polar bears, caribou, and
Arctic foxes
...
Ecosystem Functions Functions of Ecosystems Ecosystems provide a wide range of functions that are vital for the survival of both
plants and animals
...Wildlife Habitat The tundra provides essential habitat for a variety of wildlife species, including caribou, musk oxen, and
Arctic foxes
...
Nutrient Cycling in Tundra Environments Analyzed Tundras are cold, treeless landscapes found in the
Arctic and high mountain regions, characterized by low temperatures, short growing seasons, and permafrost
...Nitrogen Fixation: Some tundra
plants have symbiotic relationships with nitrogen-fixing bacteria, allowing them to convert atmospheric nitrogen into a form usable by plants
...
Human Activities Affecting Tundra Ecosystems The
Arctic tundra is experiencing rapid warming, leading to the melting of permafrost and changes in precipitation patterns
...Overgrazing can also lead to soil erosion and degradation, making it difficult for
plants to regrow and for wildlife to find suitable habitat
...
Effects of Climate Extremes on Tundras Tundras are vast, treeless regions found in the
Arctic and Antarctic, characterized by low temperatures and short growing seasons
...Changes in snowfall and rainfall can impact the availability of water for
plants and animals, as well as the formation of ice layers that insulate the ground during winter
...
Effects of Melting Permafrost on Tundras Tundras are vast, treeless regions found in the
Arctic and Antarctic characterized by low temperatures and short growing seasons
...As the frozen soil thaws, it becomes waterlogged, making it difficult for
plants to establish roots and access nutrients
...
Cold Deserts and Snow Cover Some
plants and animals have adapted to thrive in snowy conditions, while others may hibernate or migrate to warmer areas during the winter months
...For example, certain animals, such as snowshoe hares and
arctic foxes, have evolved white fur to blend in with the snowy landscape and avoid detection by predators
...
Boreal Forests These forests are primarily found in the northern hemisphere, encircling the
Arctic region
...The soil in boreal forests is often acidic and nutrient-poor, which influences the types of
plants that can thrive in this biome
...
Tundra Ecosystem Functions and Resilience Adaptation Mechanism Description Seasonal Migration Many tundra species, such as caribou and
Arctic terns, have evolved seasonal migration patterns to cope with the changing environmental conditions
...Thermal Regulation Tundra
plants and animals have developed specialized adaptations to regulate their body temperatures in extreme cold, such as thick fur and insulation
