  • What is the biosphere defined as?
    A global ecological system
  • What is the hydrosphere composed of?
    Water on Earth
  • The biosphere is the global ecological system that encompasses all living organisms and their interactions with the atmosphere, hydrosphere, and lithosphere
  • The hydrosphere includes all water on Earth, such as oceans and lakes
  • Match the biosphere component with its description:
    Atmosphere ↔️ Gases surrounding Earth
    Hydrosphere ↔️ Water including oceans and lakes
    Lithosphere ↔️ Rocky crust and upper mantle
  • The atmosphere protects the lithosphere from harmful radiation and provides nutrients
  • What gas does the atmosphere provide for respiration?
    Oxygen
  • The three main components of the biosphere are the atmosphere, hydrosphere, and lithosphere
  • The atmosphere provides oxygen for respiration, while the hydrosphere provides water
  • The primary energy source for the biosphere is sunlight
  • What percentage of energy is passed on to primary consumers in the biosphere?
    10%
  • The atmosphere supports life by providing breathable air.

    True
  • Match the biosphere interaction with its description:
    Atmosphere-Hydrosphere ↔️ Oxygen for respiration, water transfer
    Atmosphere-Lithosphere ↔️ Protection from radiation, nutrient provision
    Hydrosphere-Lithosphere ↔️ Erosion, release of minerals
  • The hydrosphere releases minerals and nutrients needed by living organisms
  • Autotrophs capture sunlight during photosynthesis to produce organic matter.

    True
  • Autotrophs like plants capture sunlight during photosynthesis
  • Arrange the trophic levels in order of energy transfer efficiency from highest to lowest.
    1️⃣ Primary Producers
    2️⃣ Primary Consumers
    3️⃣ Secondary Consumers
    4️⃣ Tertiary Consumers
  • The inefficient energy transfer creates the characteristic pyramid structure of ecosystems.
  • What are the major nutrient cycles in the biosphere?
    Carbon, nitrogen, phosphorus, water
  • In the carbon cycle, photosynthesis and respiration drive the exchange of carbon between the biosphere components.
  • Weathering and erosion release phosphorus into aquatic systems during the phosphorus cycle.

    True
  • What are the main factors affecting the biosphere?
    Climate change, pollution, habitat destruction, overexploitation
  • The factors affecting the biosphere can lead to changes in ecosystem functioning and loss of biodiversity.

    True
  • Reducing environmental pollution involves limiting the release of pollutants into the atmosphere, hydrosphere, and lithosphere.
  • Why is biosphere conservation essential for the long-term viability of life on Earth?
    Maintains ecosystem interconnectedness
  • The biosphere includes interactions with the atmosphere, hydrosphere, and lithosphere.
    True
  • The biosphere components are independent of each other.
    False
  • What does the lithosphere provide for the biosphere?
    Nutrients and habitat
  • The interconnectedness of biosphere components is essential for sustaining life on Earth.

    True
  • What is the primary exchange between the atmosphere and hydrosphere?
    Water cycle
  • Describe the interaction between the hydrosphere and lithosphere:
    1️⃣ The hydrosphere erodes the lithosphere
    2️⃣ Minerals and nutrients are released
    3️⃣ Living organisms use these minerals
    4️⃣ The lithosphere provides the physical environment
  • The lithosphere releases carbon dioxide into the atmosphere.

    True
  • Match the biosphere interaction with its description:
    Atmosphere-Hydrosphere ↔️ Oxygen for respiration, water transfer
    Atmosphere-Lithosphere ↔️ Protection from radiation, nutrient provision
    Hydrosphere-Lithosphere ↔️ Erosion, release of minerals
  • The lithosphere releases carbon dioxide into the atmosphere
    True
  • Order the steps of energy flow in the biosphere:
    1️⃣ Sunlight is captured by autotrophs
    2️⃣ Photosynthesis produces organic matter
    3️⃣ Energy is transferred through food chains
    4️⃣ Only about 10% of energy is passed to the next level
  • The biosphere is the global ecological system that includes all living organisms and their interactions with the atmosphere, hydrosphere, and lithosphere
  • The lithosphere supports life by offering nutrients and habitat
  • Which cycle transfers water between the atmosphere and hydrosphere?
    Water cycle
  • What percentage of energy is transferred between trophic levels in the biosphere?
    10%
  • What is the primary energy source for the biosphere?
    Sunlight
