  • the location within an ecosystem that meets the living needs of particular plant or animal species: the shelter, food, and space they require to survive.
    habitat
  • organisms within an ecosystem that derive their food from dead organisms
    decomposers
  • organisms within an ecosystem that derive their food from producers
    primary consumers
  • all the organisms of one species living in an area
    population
  • 3 impacts of deforestation.
    habitat loss, depletion of biodiversity and gene pool, global warming and climate change, soil erosion, desertification
  • the process that takes place in mitochondria cells where enzyme control the release of energy together with carbon dioxide and water when glucose reacts chemically with oxygen.
    respiration
  • 2 causes of soil erosion.
    deforestation and overgrazing of animals
  • sustainable ways of using tropical rainforest
    selective loggings, hydroelectric power stations, agro-forestry, national parks, ecotourism, harvesting fruits
  • genetic diversity is also called as . . . .
    gene pool
  • The community of living animals, plants, and microorganism species in an area and how they interact with each other and with non-living elements of the environment.
    ecosystem
  • organisms within an ecosystem that derive their food from producers.
    primary consumer
  • a group of the populations of different species that live in an area and interact with each other
    community
  • 3 benefits of ecotourism on tropical rainforests
    education,sustain the wellbeing of the local people, income for local people for accomodation, encourage the local people to conserve the forest ecosystem,
  • sucesion of organism that eat another organism and are, in turn eaten themselves.
    food chain
  • maintaining water cycle and preventing soil erosion are functions of forest, 3 other functions of forest are . . . .
    biodiversity and genetic gene pools, food and industrial raw materials, carbon sinks and stores, ecotourism.
  • The range of species number and variety of living things.
    biodiversity
  • The most important reason for deforestation.
    Farming/agriculture
  • Clearing Earth's forests on a massive scale.
    Deforestation
  • 3 reasons for deforestation.
    farming practices, agriculture, urbanization, oil mining, rocks and minerals mining, transportation links
  • the process of converting carbon dioxide and water by the radiant energy of the Sun into glucose and oxygen.
    photosynthesis
