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?
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?
