5.2 Epping Forest CASE STUDY Flashcards
1
Q
How are trees adapted to the UK’s seasonal climate?
A
- Deciduous and lose their leaves in the winter
2
Q
How do trees in the UK maximise their photosynthesis during the summer?
A
- Grow broad green leaves during Spring
3
Q
Why do trees in the UK shed their leaves in Autumn?
A
- conserve energy during the winter
- by mid-autumn the floor is covered by a thick layer of leaves
4
Q

- leaf litter has disappeared and decomposers and detritivores have broken in down
5

What happens to the nutrients stored in leaves?
A
- Converted to hummus in soil to support new plant growth
6

How are humans interdependent with the woodland?
A
- Coppicing (cutting back trees to encourage new growth of wood)
- Picking berries and flowers which spread the seed

13
Q
What is the role of a producer in an ecosystem?
A
- Create their own food through photosynthesis

14

A
- Breaks down DOM which returns nutients and energy to soil
