Local Factors And Biomes Flashcards
What type of biome is the UK characterised by
Temperate deciduous forest
Which biomes are associated with North Africa?
Desert, Mediterranean
What biomes are found in the Northern Polar region?
Tundra, Boreal forest
Which biome is located at the Equator?
Tropical rainforest
What local factor affects the UK’s ecosystems related to rock and soil type?
Chemical weathering of rocks releases nutrients and chemicals
The acidity or alkalinity of the soil influences plant growth.
How does water availability affect soil in the UK?
Depends on precipitation/evaporation
Sandy soils tend to be dry, while clay soils retain more water and are generally wetter.
What is the effect of altitude on ecosystems?
High altitudes often mean below freezing temperatures
Rainfall increases with height, and trees cannot grow above the treeline due to cold conditions.
What does altitudinal zonation refer to?
Changes in temperature and precipitation with height
What does Biotic refer to in an ecosystem?
Made up of plant (flora) and animal (fauna) life
What does Abiotic refer to in an ecosystem?
Includes atmosphere, water, rock, soil
Why are all forests in the UK different?
Different conditions are needed for different plants
What type of soil is primarily found in oak forests?
Mostly neutral, slightly acidic soil
Willow and alder trees are typically found in what type of areas?
Waterlogged, marshy areas, river banks
Beech and ash trees prefer what type of soil?
Limestone and chain, slightly alkaline soil
The soil pH affects the nutrient availability for these trees.
What conditions do Scots pine and birch trees require?
High rainfall, acidic soils with few nutrients
These trees are adapted to harsh soil conditions.
