Spheres of Earth
Identify all 4 spheres of Earth.
Atmosphere, hydrosphere, biosphere, geosphere
Identify 1 energy process that you have learned this week and explain the goal of it.
Many different answers accepted:
Chemosynthesis
Photosynthesis
Respiration
Decomposition
Combustion
What does CO2 stand for?
Carbon Dioxide
Inputs: oxygen + glucose
Outputs: CO2 + water + ATP
What is the difference between biotic and abiotic factors?
Biotic = living
Abiotic = nonliving
Fish need to live in environments with water.
Identify the two spheres of Earth mentioned.
Biosphere and hydrosphere
Decide if the following statement is true or false and explain why.
Humans can do photosynthesis during the day time.
False because humans are not able to convert light energy into chemical energy (glucose).
Describe the movement of carbon during photosynthesis between 2 Earth spheres.
Carbon moves from the atmosphere to biosphere.
Identify the inputs and outputs of photosynthesis and identify 1 organism that does this process.
Inputs: water + sun + CO2
Outputs: glucose + oxygen
Organisms: Plants, trees, flowers, some bacteria, algae
What is the difference between an independent variable and dependent variable?
Independent variable is what is changed.
Dependent variable is what is measured.
Why are microbes (microorganisms) part of the biosphere?
Because they are living things / they are alive
What is another name for glucose?
Describe the movement of carbon during chemosynthesis between two Earth spheres.
Carbon moves from the hydrosphere to biosphere.
Why is respiration important for living things?
Because it produces energy (ATP) that can be used to move, grow, develop.
Explain what quantitative data is and give an example.
Quantitative data = numbers
Example: Many answers accepted.
Explain what would happen to the amount of carbon in the atmosphere if photosynthesis increases in an area.
The amount of carbon in the atmosphere would decrease because it is needed for more photosynthesis.
Identify the name of the energy produced during respiration and explain why it's important.
ATP is important because it allows living things to move, grow, develop.
Describe how trees would be impacted if the amount of carbon in the atmosphere decreased.
If atmospheric carbon decreases, trees would decrease their photosynthetic activity.
Explain how plants would be affected if animals stopped doing respiration.
This would decrease plants' ability to do photosynthesis because they have less carbon available.
When an animal dies, fungi and bacteria will break it down into smaller pieces (nutrients) that go to soil (ground).
Identify the process that is occurring and identify 1 sphere of Earth involved.
Process = Decomposition
Sphere of Earth:
Biosphere = animal dies / fungi / bacteria
Geosphere = nutrients in soil
Explain how carbon moves through different spheres of Earth during photosynthesis.
Carbon starts in the atmosphere and then goes to plants in the biosphere.
There is no sunlight deep in the ocean. However, microorganisms have developed other ways to get energy.
Identify the energy process they use and explain how.
They use chemosynthesis.
They use chemicals to produce food.
Decide "yes" or "no" to the following question and explain why.
Can living things exist without carbon?
No because all living things are made of carbon.
Explain how photosynthesis and cellular respiration are connected.
Photosynthesis produces oxygen that animals can use during respiration.
OR
Respiration produces carbon that can be used during photosynthesis.
