    • Buttress roots
      Support tall trees in the shallow, nutrient poor soil
    • Canopy
      The layer of a tropical rainforest where the tops of trees touch, forming a dense area of vegetation
    • Deforestation
      The permanent removal of trees
    • Drip-tip
      Allows heavy rain to drip off leaves easily to prevent water from collecting and causing rot
    • Ecotourism
      Tourism that aims to have reduced environmental impacts and supports conservation efforts, making it sustainable
    • Lianas
      Vines that have roots in the ground but climb up trees to reach sunlight at canopy
    • Selective logging

      A form of logging where only certain trees are cut down to reduce the environmental effects of logging
    • Transmigration

    • Tropical rainforest
      A warm, wet, biodiverse ecosystem located within the Tropics
    • Understory

    • Abiotic components
      Non living, for example, air, water and heat
    • Biome

    • Biotic components
      Living organisms, for example, plants, insects and animals
    • Ecosystem

    • benefits of deforestation
      obtain timber products, more job opportunities and access to natural resources that lie within the forested areas
    • Rainforests are disappearing due to human activity like…
      Logging, mineral extraction, road building, commercial farming
    • Soil erosion
      Removal of the top layers of soil by rainwater, wind and destructive human activities
    • Mineral extraction
      Causes soil and water contamination, large environmental degradation
    • Logging
      Timber is harvested to create commercial goods such as furniture and paper, leading to habitats being destroyed
    • Commercially farming
      Huge areas of land cleared to make space for plantations, which are mostly illegal with little consideration for the environmental impact
