- 1Area and Climate of Tropical Rainforests?Central America, North and South America (Amazon).
It is hot and wet, with no real seasons. - 2What's the soil like in the Rainforest?Not very fertile as heavy rain washes nutrients away. There are nutrients at the surface due to decayed leaf fall, but it's a thin layer as decay is fast in the warm, moist conditions.
- 3What's the structure of Vegetation in the Rainforest?There's three layers and a shrub layer.
- 4What is the Undercanopy and Canopy like?The canopy is a continuous layer of trees ~30m high.
The undercanopy trees are about half the height of canopy trees. - 5What's the emergents and Shrub Layer like?Emergents are 40m and poke out of the canopy.
The shrub layer is nearest to the ground at around 10m high. Very little light reaches it. - 6How are Plants adapted to live in the Rainforest?They are adapted to the heavy rainfall by having thick waxy leaves with Drip-tips so water runs off.
Trees have buttress roots for support.
Lianas use tree trunks to climb up to the light. - 7What's the Climate and Location of Hot Deserts?North Africa, Middle East, South West USA.
Very little rainfall. When it rains is very varied, may only happen once in 2 or 3 years.
Temperatures are extreme ranging from 5 - 45. - 8What's the soil like in Hot Deserts?It shallow with a coarse, gravelly texture.
There's hardly leaf fall, so the soil is infertile. - 9What's the vegetation structure of Hot Deserts?Plant Growth is pretty sparse due to lack of rainfall. Plants do grow including cacti.
- 10How are Plants Adapted to Live in the Desert?Plant Roots are really long or spreadout to get water ASAP.
Caci have swollen stems to store water and thick waxy skin to reduce water loss.
Cacti and some bushes also have small, spiky leaves, reducing water loss. - 11Where are Deciduous Forests and What's their climate?Most of Europe, South East USA, China
It has four distinct seasons
Summer is warm and Winter is cool.
Rainfall is all year round. - 12What's the soil like In Forests?Deep and Fertile due to the thick layer of leaf fall.
- 13What is the Vegetation Structure of the Forest?At ground level is a layer of undergrowth.
At the middle level there are smaller trees.
The top layer is made up of trees ~30m tall. - 14How are Plants Adapted in a Forest?Trees are Deciduous. This reduces water loss from leaves in the months when water is hard to get from soil as it may be frozen, and there isn't much light for photosynthesis.
Wildflowers grow on the forest floor in spring before the trees grow leaves blocking out sunlight.
