3
Q
Where are tropical rainforests found
A
South America, West Africa etc
4
Q
Examples of Tropical Rainforest
A
The Amazon
Congo Basin
Atlantic forest
5
Q
Tropical rainforest climate
A
- Humid
- Rains most days
6
Q
Conventional rain
A
- Occurs when the sun’s energy heats the Earth, causing water/moisture to evaporate to form water vapour
- the vapour rises, cools, and condenses to form clouds high in the atmosphere
7
Q
Why is biodiversity high (4p)
A
- Stable climate with high temperatures and high rainfall
- Layered structure
- Large area untouched by humans
- Rapidly recycled nutrients
8
Q
How does the climate increase biodiversity?
A
The steady climate provides ideal conditions for many plants and animals to thrive
9
Q
How does the rainforest layers help with biodiversity?
A
- Creates numerous habitats and supports a range of species
10
Q
How does How does a rapid nutrient cycle help with biodiversity?
A
It’s speeds up plant growth and provides food for the food chain
11
Q
Nutrient cycle
A
- Nutrients enter soil
- Shallow roots take up nutrients
- Nutrients help the plant to grow rapidly
- Plants sheds leaves and decaying vegetation decomposes rapidly releasing nutrients
12
Q
Interdependence in plants
A
The nutrient cycle
