Biodiversity & Conservation
This term refers to the variety of life in all its forms, levels, and combinations.
What is biodiversity?
Human-caused factors that contribute to global warming.
What are anthropogenic causes?
Evolution is defined as a change in this over generations.
What are genes/heritable characteristics?
This term refers to a group of organisms of the same species living and interacting in the same area.
What is a population?
Gas exchange is necessary for this cellular process.
What is respiration?
One major anthropogenic cause of species extinction.
What is habitat destruction or overexploitation?
Provide an example of how the polar climate has changed, affecting habitats.
What is the melting of sea ice or landfast ice?
Breeding dogs or crops for specific traits provides evidence of this.
What is artificial selection or selective breeding?
This method is used to estimate the population size of sessile (non-moving) organisms like plants.
What is quadrat sampling?
These structures in mammalian lungs increase surface area for exchange.
What are alveoli?
This term explains the increase in pollutants as you move up trophic levels.
What is biomagnification?
This type of feedback cycle accelerates an effect, like global warming.
What is a positive feedback loop?
The structure of a human arm and a bat wing are examples of this type of structure.
What are homologous structures?
This term refers to an organism that can exist as either an autotroph or heterotroph.
What is a mixotroph?
This maintains the concentration gradient for oxygen in animal lungs.
What is ventilation (breathing)?
This aquatic process is caused by leaching of nutrients like nitrates into water systems.
What is eutrophication?
This issue explained why the Amazon rainforest can face a tipping point from a carbon sink to a carbon source.
What is deforestation?
This process separates one species into two due to genetic, geographic, or temporal isolation.
What is speciation?
This ecological interaction benefits both species involved.
What is mutualism?
These small pores regulate gas exchange and water loss in plant leaves.
What are stomata?
Coral reefs face environmental threats that can affect the stability of marine ecosystems because of their fundamental role. They are an example of this.
What is a keystone species?
Provide an ecosystem solution that helps remove carbon from the atmosphere.
What is afforestation, forest regeneration, or peatland restoration?
A non-random form of selection based on traits that improve mating success.
What is sexual selection?
The transfer of energy from one trophic level to the next results in this consequence/"rule" that limits the number of trophic levels.
What is the 10% rule or loss of energy (typically ~90%) as heat?
This term explains the relationship between pressure and volume during ventilation.
What is an inverse relationship?
