Main Components
What gas is used as an input in the process of photosynthesis?
Carbon dioxide.
Are plants autotrophs or heterotrophs?
Autotrophs.
Tree take in the ____ exhaled by the living organisms.
Carbon dioxide
Would multicellular organisms be able to exist without the oxygen cycle.
No, because all organisms need oxygen to breathe and survive.
What gas is an output/waste product of photosynthesis?
Oxygen.
What process is the "sister" or "opposite" to photosynthesis?
Respiration.
What does burning fossil fuels release in the atmosphere?
Carbon dioxide/greenhouse gas
Why do oxygen levels decrease in water nowadays?
Due to human input of excess nutrients, which affects not only algae but also fish and other aquatic organisms.
What are the main components of the oxygen cycle?
Atmosphere, Plants and Photosynthesis, Animals and Respiration, Decomposition and Combustion. (One of the previous).
Where is the ozone layer naturally formed?
In the stratosphere.
How may humans be affected by the carbon dioxide they release from pollution?
They may suffer from skin issues, damaged respiratory systems, etc.
How does the oxygen cycle connect to the carbon cycle?
By serving the important function in climate regulation by contributing to balancing greenhouse gases.
What is the purpose of the atmosphere?
The purpose of the atmosphere is to act as a layer of gas that holds everything in on Earth while also acting as a protective layer.
What does chlorophyll do?
1) Capture sunglight
2) Producing ATP
What are ways to obtain energy other than burning fossil fuels?
Solar energy, hydroelectric energy, wind energy, etc.
What do aquatic animals use to respire?
Their gills.
What is the importance of decomposition and combustion?
To release carbon found in dead organic matter.
What is the second step (mentioned in the slides) of photosynthesis?
Converting energy to glucose.
How much does oxygen make up of the atmosphere?
21%
The oxygen cycle connects all of the processes listed earlier and ensures that there is a _____ between all ecosystems
Balance
