    What are the 3 types of ecosystems?

    They include Niche - A bee pollinating flowers, Medium - A woodland ecosystem, and Biome - Tropical rainforest biome (Amazon, Congo)

    Name all the main biomes and their location.

    🌳 Tropical rainforest Near the Equator 🏜️ Desert Around Tropic of Cancer & Capricorn 🌾 Grassland Africa, North America ❄️ Tundra Near the Arctic Circle 🌲 Temperate forest Europe, parts of Asia & North America

    How do plants adapt to tropical rainforests?

    🌿 Plants: Drip-tip leaves β†’ water runs off quickly so plants aren't damaged by its weight Waxy leaves β†’ prevents rotting from water settling on the leaf Buttress roots β†’ support tall trees from breaking Tall trees β†’ reach sunlight in the emergent layer and thive

    What are the layers of the rainforest?

    Emergent layer (tallest trees) Canopy (dense layer, most life) Understorey (shaded, smaller plants) Forest floor (dark, little growth)

    What elements are in the nutrient cycle of the rainforest?

    Key elements include carbon, nitrogen, and phosphorus.

    What are some main threats to tropical rainforests?

    🌳 Deforestation (logging) 🚜 Farming (slash and burn) πŸ„ Cattle ranching ⛏️ Mining πŸ›£οΈ Road building 🌍 Climate change

    How can threats to the rainforest be reduced?

    Laws to limit deforestation Protected areas (national parks) Replanting trees Education on sustainable farming Sustainable logging

    What is sustainable management of tropical rainforests?

    Selective logging (cut few trees) Replanting trees (stops deforestation and climate change) Ecotourism (small-scale tourism that minimizes environmental impact, creates jobs for locals, and generates funds for conservation) Agroforestry: Growing trees and crops together to prevent land degradation and reduce the need for clearing new forest areas

    Why is ecotourism better for rainforests?

    🌍 Ecotourism: Protects environment Creates jobs for locals Encourages conservation

    Why is sustanable farming better for rainforests?

    🌱 Sustainable farming: Doesn’t destroy soil Long-term food supply Protects biodiversity

    How do animals adapt to tropical rainforests?

    πŸ’ Animals: Strong limbs/tails β†’ climbing Camouflage β†’ hide from predators Bright colours β†’ warning (poison) Nocturnal β†’ avoid heat/predators
