The Earth
These break down organic matter in the soil
What are Fungi and Bacteria?
This gas is produced via photosynthesis.
What is Oxygen? (O2)
Rises in sea level are primarily due to the loss of this.
What are Polar Ice Caps?
What is a generalist species?
The main sinks for this element are forests or oceans.
What is Carbon?
These are the 3 main categories of soil texture.
What are sand, silt, and clay?
This gas constitutes 78% of the Earth's atmosphere and is the most abundant of all atmospheric gases.
What is Nitrogen (N2)?
This type of irrigation minimizes water loss by slowly adding water to the roots of plants.
What is Drip Irrigation?
This describes close and often long-term interactions between biological species.
What is symbiosis?
When water vapor leaves the stomata of plant leaves and enters the atmosphere.
What is transpiration?
This is the productive layer of soil where most crops are grown.
What is topsoil?
The volume of this gas has increased roughly 25% in the last 300 years.
What is Carbon Dioxide (CO2)?
This property of water allows it to absorb large amounts of solar energy.
What is specific heat capacity?
Species whose extinction would lead to the collapse of an ecosystem.
What is a keystone sepcies?
The result of nitrogen or phosphorus pollution of waterways creates dead zones for organisms.
What is Eutrophication?
This is the result of a sudden transform shift in tectonic plates.
What is an Earthquake?
This is the layer of Earth's atmosphere in which weather occurs.
What is the Troposphere?
These biologically sensitive ecosystems are the first to suffer when ocean levels rise.
What are Wetlands?
This refers to the spacing of organisms in an ecosystem.
What is population dispersal?
This is the process of gaseous nitrogen converting into forms usable by living organisms.
What is Nitrogen Fixation?
This tectonic boundary type results in seafloor spreading.
What are divergent plate boundaries?
This is the main driver of global air circulation.
What is solar radiation?
This 1972 act aimed to restore and maintain the integrity of the nation's water resources.
What is the Clean Water Act?
A series of changes that occur in an ecological community that occur over time after a disturbance.
What is ecological succession?
Destruction of these ecosystems can disrupt natural processes that purify water.
What are Wetlands?
