Y9 Biomes Test Flashcards
Define a Biome
A biome, also known as an ecosystem, share similar climates and life forms
What are examples of biomes
Forests, deserts, grassland, tundra and aquatic biomes
What does the landscape of a forest look like?
The landscape of forests are typically an unbroken expanse of natural ecosystems with dense canopies of vegetation
What animals are found in a forest
Rainforest animals consist of monkeys, parrots and jaguars
What is the climate like in a forest biome?
Climates range from hot, wet and humid
Threats to forest biomes
Deforestation from big companies who want land for farms and businesses
Landscape of tundra biomes
Tundra biomes are arctic, treeless biomes usually found at mountain tops with grasses and dwarf shrubs
Animals found in tundra biomes
Polar bear, arctic fox, snowy owl and musk ox
Climate of tundra biome
Extremely cold temperatures below 0 degrees for most of the year
What are the three different regions of a tundra
Arctic, Antarctic and alpine. Arctic regions contain permafrost
Threats to tundra biomes
Global warming effects tundra biomes the most because of the plants and animals that have little to no tolerance to changes in climate and the snow layers
Landscapes of aquatic biomes
Freshwater and marine regions in seas, lakes, rivers and more. Coral reefs
Animals in an aquatic biome
Turtles, fish, sharks, alligators and frogs
Climate in aquatic biomes
Hot and cold temperatures spawning from 4 degrees Celsius to 22 degrees Celsius
Climate in aquatic biomes
Hot and cold temperatures spawning from 4 degrees Celsius to 22 degrees Celsius
Threats to aquatic biomes
Plastic pollution, oils spills, climate change and entanglement in fishing gear
Landscape of desert biomes
Layers of soil that can be sandy, gravelly or stony depending on the desert. Large dry areas of land with sparse vegetation
Animals in a desert biome
Scorpions, camel, kangaroo rat, addax and armadillo lizard
Climate in desert biomes
Dry climate with temperatures spanning from 38 degrees C during the day and -3.9 degrees C overnight
Threats to desert biomes
Grazing animals, habitat destruction and water scarcity
Landscape of grassland biomes
Large open areas of grass with small widely spaced trees with rainfall and soil unable to support significant tree growth
Animals found in grassland
Bison, wolf, deer, zebra, eagle and African wild dog
Climate of grassland biomes
Grasslands consist of very or summers and cold winters which determine the vegetation that the biome will get
Threats to grassland biomes
Overgrazing, invasive species, illegal hunting and climate change
What factors influence climate in biomes
Soil, longitude and latitude, altitude, ocean currents and air movement
Why is soil in biomes important
Soil in biomes determines what animals and plants are going to inhabit the biome. The amount of vegetation also impacts the quality of the soil as well as the biomes location in terms of the equator
What role do microorganisms and bacteria found in soil
The bacteria and micro organisms play a huge role in maintaining soil fertility and quality by composting waste and fertilising soil, improve drainage and aeration, bring subsoil to the surface and mix it with topsoil and secrete nitrogen which helps bind soil.
