    • What are the learning objectives regarding tropical rainforests?
      Characteristics of tropical rainforests, interdependence, and adaptations of plants and animals
    • What are the characteristics of tropical rainforests?
      • Contains more animal species than any other ecosystem
      • Many indigenous people adapt by hunting, farming, and fishing
      • Most trees are evergreen
      • Dense vegetation cover with little light reaching the forest floor
      • Presence of epiphytes
      • Soil is not very fertile but has surface nutrients from decayed leaf fall
    • What is the average temperature range in tropical rainforests?
      Between 20 to 28 degrees Celsius
    • Why is the climate in tropical rainforests consistent throughout the year?
      Because the sun's energy is most intense near the equator and is overhead all year round
    • How much rainfall do tropical rainforests receive annually?
      Around 2,000 millimeters per year
    • What does interdependence mean in the context of tropical rainforests?
      • All parts of an ecosystem depend on one another
      • A change in one part affects the entire system
    • How do sucropia trees and azteca ants demonstrate interdependence?
      Sucropia trees provide food and shelter for azteca ants, while ants protect the trees from predators
    • What are some adaptations of plants in tropical rainforests?
      • Lianas: climb trees to reach sunlight
      • Tall and thin tree trunks: to access sunlight
      • Smooth bark: allows water to flow easily
      • Drip tips: help water run off leaves quickly
      • Buttress roots: provide support for large trees
      • Epiphytes: obtain nutrients from air and water
    • What is the function of lianas in tropical rainforests?
      They climb trees to reach sunlight
    • Why do trees in tropical rainforests have smooth bark?
      To allow water to flow down to the roots easily
    • What is the purpose of drip tips on rainforest plants?
      To allow water to run off quickly without damaging the leaves
    • What are buttress roots and their function?
      Large roots with ridges that create a large surface area to support large trees
    • What are some adaptations of animals in tropical rainforests?
      • Sloth: uses camouflage and moves slowly
      • Spider monkey: has long strong limbs for climbing
      • Flying frog: has webbed hands and feet for gliding
      • Toucan: has a long bill to reach fruit on weak branches
    • How does the sloth avoid predators in the rainforest?
      By using camouflage and moving slowly
    • What adaptation helps the spider monkey navigate through the rainforest?
      Long strong limbs for climbing trees
    • How does the flying frog glide from plant to plant?
      By using fully webbed hands and feet along with loose skin between its limbs
    • What is the function of the toucan's long bill?
      To reach and cut fruit from branches that are too weak to support its weight
    • What is the average annual rainfall in hot deserts?
      250 millimeters per year
    • Why do hot deserts experience extreme temperature changes?
      Due to the lack of moisture and cloud cover
    • What is the temperature range in hot deserts from day to night?
      From 45 degrees Celsius during the day to 0 degrees Celsius at night
    • How does low rainfall affect soil fertility in hot deserts?
      It limits the soil's fertility and often leaves it dried out
    • What type of plant growth is typical in hot deserts?
      Sparse and usually low and short
    • What adaptations do mammals in hot deserts typically have?
      Mammals tend to be small and nocturnal
    • Where do people typically grow crops in hot deserts?
      Near natural water sources, usually in the desert fringes
    • What is a common lifestyle of indigenous people in hot deserts?
      They are often nomadic and travel to find food and water
    • What are the main adaptations of plants in hot deserts?
      • Small leaves to reduce water loss by transpiration
      • Tap roots that reach deep underground for water
      • Spines instead of leaves to minimize water loss
      • Waxy skin on leaves to reduce transpiration
      • Water storage in stems, leaves, roots, or fruits
    • What is the purpose of tap roots in desert plants?
      To access deep water supplies
    • Why do some desert plants have spines instead of leaves?
      Spines lose less water than leaves and prevent animals from eating the plant
    • What is the function of the thick waxy skin on some desert plants' leaves?
      To reduce water loss by transpiration
    • How do succulents store water?
      In their stems, leaves, roots, or fruits
    • What are the main adaptations of camels in hot deserts?
      • Long eyelashes and hairy ears to keep out sand
      • Clothing nostrils to prevent sand inhalation
      • Thick eyebrows to shade eyes from the sun
      • Wide feet to avoid sinking into sand
      • Ability to go without food or water for extended periods
      • Body temperature can change to minimize water loss
      • Well camouflaged and thick fur for warmth at night
    • How long can camels go without food or water?
      They can go without food for months and without water for over a week
    • What is the advantage of a camel's wide feet in the desert?
      They prevent the camel from sinking into the sand
    • How do the adaptations of camels help them survive in hot deserts?
      They minimize water loss and protect against harsh conditions
    • What does desertification mean?
      Desertification is the degradation of land making it drier and less productive.
    • What role do camels' thick fur play in their survival?
      It helps keep them warm at night
    • What fraction of the Earth is at risk of desertification?
      One third of the Earth is at risk of desertification.
    • What is the process of desertification?
      • Vegetation dies or is removed
      • Exposed soil is easily eroded by wind or water
      • Loss of nutrients makes the soil unproductive
    • What are the two main causes of desertification?
      The two main causes of desertification are climate change and human activities.
    • How does climate change contribute to desertification?
      Climate change affects rainfall and is expected to reduce rainfall in already dry areas.
