TOPIC 3C: Deciduous woodlands πͺ΅π¦ Flashcards
What are deciduous woodlands ?
- deciduous woodlands, are vegetation that loses its leaves every year, due to seasonal changes
What are the abiotic characteristics of deciduous woodlands ?
- the abiotic characteristics of deciduous woodlands are:
- climate
- soil
- and, water
What are the biotic characteristics of deciduous woodlands ?
- the biotic characteristics of deciduous woodlands are:
- plants
- animals
- and, humans
What is the climate of deciduous woodlands ?
Hint: bewteen
- the climate in deciduous woodland regions are highly seasonal.
- this means, the climate greatly varies between the winter months [e.g- December] and the summer months [e.g- July]
What is the climate of deciduous woodlands in the winter ?
Hint: freeze
- in the winter months of deciduous woodlands, the temperature remains above zero- which means the soil doesnβt freeze over in the winter.
- and the rainfall in the winter months, is four times less during summer; the level of rainfall still remains high
- Fill in the gaps: In ________ woodlands, the vegetation cover decreases and leaves fall off trees- this is to minimise energy and moisture loss.
- ; in deciduous woodlands, the vegetation cover decreases and leaves fall off trees- to minimise energy and moisture loss.
What is the climate of deciduous woodlands in the summer ?
Hint: vegetation
- in the summer [of deciduous woodlands], there are high levels of rainfall and temperatures
- ; in the summer, vegetation cover increases largely, with leaves growing back and small plants on the woodland floor
How is water an abiotic characteristic of deciduous woodlands ? [Hint: throughout]
- in deciduous woodlands, levels of rainfall are high, as it is between 500-1500 mm per year
- and in deciduous woodlands, rain falls throughout the year- and it supplies: lakes, streams and rivers
How are plants an abiotic characteristic of deciduous woodlands ? [Hint: large]
- trees in deciduous woodlands typically have large broad leaves, such as: oak, beach and elm trees.
- These trees form the canopy layer; vegetation is also layered in deciduous woodlands. This is because, some light is able to get through
What can you tell me about the shrub layer, of deciduous woodlands ? [Hint: beneath]
- the shrub layers forms beneath taller trees, and tree species such as: hazel, ash and holly are found in the shrub layer.
- [; the ground layer can also contain grass or bluebells]
How is soil, an abiotic characteristic of deciduous woodlands ? [Hint: rich]
- deciduous woodlands, have very rich soil and humus
- ; the soil in deciduous woodlands, is also fertile brown earth and during the autumn [season], leaves fall of from the tree and decompose- contributing to soil nutrients.
What is humus ?
Hint: not rich
- humus, is a dark and organic material that forms in the soil during decomposition
How is the Gersmehl model different in deciduous woodlands, in comparison to tropical rainforests ? [Hint: why ?]
- The Gersmehl model illustrates that in deciduous woodlands,
biomass and soil stores are larger than the litter store. - ; in tropical rainforests, the litter
store is smaller because of decomposition.
Why do deciduous woodlands have less biodiversity, compared to tropical rainforests ? [Hint: why?]
- less nutrient cycling in winter due to colder temperatures and less sunlight
- smaller size ecosystem than the tropical rainforest
- higher latitude, which means a lower temperature and less sunlight hours, so less photosynthesis
[Easy] Why do plants and animals have to adapt in deciduous woodlands ?
- plants and animals have to adapt, as the four distinct seasons of deciduous woodlands forces them to adapt
