What are ecosystem services?
|
Ecosystem services are the essential, life-sustaining benefits that ecosystems provide to humanity.
|
|
|
What do natural and agro-ecosystems convert CO2 into?
|
Natural and agro-ecosystems convert CO2 into biologically-useful carbohydrates that we use as food, fiber, and fuel.
|
|
|
What do natural and agro-ecosystems generate?
|
Natural and agro-ecosystems generate the O2 essential for cellular repsiration (ATP synthesis) and ozone layer formation.
|
|
|
What do primary producers remove from the atmosphere and water?
|
Primary producers remove CO2 from the atmopshere and water. Therefore, ecosytems lessen the greenhouse effect.
|
|
|
Why is soil essential for human survival?
|
Without soil, we cannot grow crops effectively.
|
|
|
What ecosystem services do wetlands and mangrove swamps provide?
|
Wetlands and mangrove swamps mitigate flooding and also remove some pollutants and toxins from water.
|
|
|
What is the role of Nitrogen-fixing species that natural and agro-ecosystems contain?
|
Nitrogen-fixing species convert N2 into biologically-useful Ammonium (NH3).
|
|
|
How can properly managed natural and agro-ecosystems affect erosion?
|
Properly managed natural and agro-ecosystems can reduce soil erosion.
Soil is essential for human health because without soil, we cannot grow crops. Dust storms (soil particles in the air) can have negative effects on the human body. |
|
|
How can properly managed natural and agro-ecosystems affect the pollination of our crops?
|
Properly managed natural and agro-ecosystems provide animal species that pollinate our crops.
|
|
|
How can properly managed natural and agro-ecosystems affect the consumption of our crop pests?
|
Properly managed natural and agro-ecosystems provide predators that consume our crop pests (biocontrol).
|
|
|
How can properly managed natural and agro-ecosystems affect the spread of disease?
|
Properly managed natural and agro-ecosystems suppress infectious disease.
Natural enemies suppress disease vectors (fleas, mosquitos, ticks, tseste flies, etc.) populations. |
|
|
Ecosystems may be sources of _________.
|
pharmaceuticals
|
|
|
How could the loss of coral reefs and rain forest ecosystems impact medicine?
|
Ecosystems are the source of pharmaceuticals.
Ecosystems are sources of agriculturally-useful and medicinally-useful genes. |
|
|
How do ecosystems mitigate the greenhouse effect?
|
Ecosystems mitigate the greenhouse effect because primary producers remove CO2 from the atmosphere and water.
|
|
|
Which ecosystem service enables ozone layer formation?
|
Natural and agro-ecosystems generate the O2 essential for cellular respiration (ATP synthesis) and ozone layer formation.
|
|
|
What is CO2 converted into by natural and agro-ecosystems?
|
CO2 is converted into biologically-useful carbohydrates that we use as fiber, fuel, and food.
