The challenges of a living world
Ecosystems
The definition of an ecosystem: An ecosystem is the community of plants and animals living together in a habitat.
There are two types of components within a habitat: The first one is Biotic (living things).
Abiotic (non living things), these are closely linked and often dependant on one another.
Micro habitats (one bush)
Habitat (a wood)
Biomes (a rain forest)
UK habitats
Montane (mountains)
Most of the animals that you can find are small mammals, dear and birds of prey.
These habitats have changes less than others in the Uk, they are generally covered with plants: gorse or heather which are much more rugged.
Grassland and Forests
Most of the UK's grassland has been made by making forests.
Most of the wildlife in the Uk rely on woodland for survival however they must have to try and survive elsewhere otherwise they will become extinct. The main driver for this change is farming because this is what it is used for now.
Main Patterns of habitats in the
Uk are as follows:
Forestry areas are much smaller than in the past.
The other major habitat in the UK is urban areas.
Across the East and South of England we have large areas of Arable farming (crops).
Across wales, northern england and southern scotland we have rough or unimproved grassland (not farmed).
Across scotland we mostly have mountainous habitats.
There is a lot of grassland. (farming)
Urban
In urban environments there are no animals or plants that occur naturally, it is a far to recent habitat. There are animals that survive in these areas by scavenging human waste. Eg foxes and rats.
Arable farmland
This is also not a natural habitat for animals or plants, the majority of farmland is clearer of any animals and plants so farmers can maximise their crops. There are a few small animals that will find away to survive eg field mice.
Causes of changes of the environment:
Human Impacts
a. Farming
b.Urbanisation - removal of habitats.
Introducing new species - these can out compete natural species or damage the natural balance of an ecosystem.
Natural Impacts
a. Climate change - Changes the types of plants affecting the food chains or making it harder for things to survive.
