Introduction to Ecology
Three types of symbiotic relationships and their definitions.
What are parasitism (+/-), Commensalism (+/0), and Mutualism (+,+) ?
An organism that produces its own energy.
What is a autotroph?
These two factors determine a biome.
What are precipitation and climate/temperature?
Name two factors used in determining aquatic ecosystems.
What are light, salinity, pH, temperature, or nutrients.
The pathway through which essential chemical elements and nutrients move between living organisms and the physical environmental.
What is biogeochemical cycles?
The interdisciplinary study of humanity's relationship with other organisms and the nonliving physical environment.
Bonus: Name three of the disciplines included.
What is Environmental Science/Natural Science?
What are economics, chemistry, biology, geology, geography, demography, physics, sociology, natural resource management, agriculture, engineering, law, politics, and ethics.
The difference between primary consumer and secondary consumer.
What is primary consumers eat autotrophs while secondary consumers eat other heterotrophs.
This biome has permafrost and is treeless.
What is the Tundra?
What are exposure to light and a supply of nutrients.
The difference between source and sink(reservoir).
What is a source releases more than it stores while a sink stores more than it releases?
The five main Earth Systems
What are Atmosphere, Biosphere, Cryosphere, Geosphere, and Hydrosphere?
What is Net Primary Productivity?
This biome typically is between 40 degrees and 60 degrees latitude and have good amounts of biodiversity and precipitation.
What is temperate rainforest?
Sediment entering fish gills causing suffocation and death is a result of this human impact on aquatic ecosystems.
What is run-off of sediments?
DAILY DOUBLE
What are evaporation, condensation, precipitation, runoff, infiltration, sublimation, transportation, percolation?
What is a niche?
Note: A fundamental niche is the theoretical range of environmental conditions and resources a species CAN USE. Realized niche is the actual portion it DOES use when limited by other living things.
A diagram that shows the total mass of living organisms at each trophic level in an ecosystem.
What is a biomass pyramid?
This biome has shrubs and grasses and few trees. Seasonal increases in precipitation occur here.
What is grassland?
DAILY DOUBLE
what is the process of the ocean becoming more acidic through an increase of atmospheric carbon dioxide -> dissolved carbon dioxide in the ocean->deformed shells?
The largest carbon sink for carbon dioxide.
What is the ocean?
The difference between positive and negative feedback loops with an example.
What is that negative feedback is a change in condition triggers a response that reverses the changed condition (a species increases and then theres less food) and a positive feedback is a change in condition that triggers an intensifying the changed condition (melting of ice leads to more absorption of solar heat by the land, which leads to more melting ice)
The 10% Rule.
What is when energy transfers from one feeding level to the next, only 10% of energy is passed on. The rest is lost to heat.
California is an example of this type of desert-like biome.
Two similarities between loss of keystone species and introduction of an invasive species.
What are that food webs are disrupted and a loss of biodiversity?
What is the lithosphere?
