Ecology
This is a living factor of an ecosystem
What is biotic?
The two most common factors that determine a biome
What are Precipitation and Temperature?
The element of life
What is Carbon?
The gas that makes up 78% of the atmosphere.
What is Nitrogen or N2?
The majority of fresh water is sequestered in this reservoir.
What are ice caps and glaciers?
This is a non-living factor of an ecosystem
What is abiotic?
This aquatic biome is characterized by its shallow, clear oceanwater in mostly tropical areas.
What is a coral reef?
Plants release both oxygen and this molecule during photosynthesis
What is carbon dioxide?
The largest reservoir of Nitrogen
What is the atmosphere?
process in the hydrologic cycle in which water vapor is released from leaves into the atmosphere
transpiration
Wetter-than-normal winters often cause summer fires due to the increased growth of this highly flammable biomass.
What is chaparral biomass?
This Biome is characterized by low average temperatures and low annual rainfall
What is a Tundra?
Deposition of organic matter on the deep ocean floor is an example of a carbon [sink or source]
What is a Carbon sink?
This organism is responsible for converting nitrogen gas into nitrates and nitrites
What are Nitrogen-fixing bacteria?
agricultural production is is often relatively high in this area where water deposits nutrients
What are floodplains?
the division of limited resources by species to help avoid competition in an ecological niche.
What is resource partitioning?
This characteristic of a biome is the measurement of biomass produced or, simply, the amount of photosynthesis occurring.
Productivity
Burning fossil fuels leads to a net increase in carbon in this gaseous sink.
What is the atmosphere?
When nitrates and nitrites are converted back into Nitrogen gas
What is denitrification?
Natural freshwater has the lowest availability per capita in this location
What is the Middle East? (or Saudi Arabia, or Qatar)
The three forms of symbiotic relationships.
What are mutualism, commensalism, and parasitism?
This is the primary biome we live in here in Giddings
What is a Savanna or Post-Oak Savanna?
Carbon returns to the atmosphere and water by these processes (must name two)
What are cellular respiration, burning, and decay?
Unlike nitrogen, this element does not cycle through a gaseous state.
What is phosphorus?
Hydropolitical issues may be the result of these factors. (name 3)
What are 1. access to freshwater, 2. climate stress(greenhouse gas emissions), 3. populations trends, 4. human pressure on the water supply, and 5. socioeconomic conditions?
