Plants and animals have adapted to the physical conditions
1. Plants
  1. Tall trees competing for sunlight have big roots.
  2. Trees have thin barks as there is no need to protect the trunk from cold temperatures.
  3. Plants drop their leaves gradually through out the year, meaning they go on growing all year round.

4. Tropical Rainforest: The Amazon
  1. 40,000 plant species. 10,000 animal species
  2. Causes of deforestation
    1. Mining
    2. Road building
  3. Effects
    1. Development and mining leads to more jobs
    2. Companies will pay taxes to the government to improve public services such as education
  4. Sustainable Management
    1. Selective Logging
