Intro to Biology
The science of life
What is Biology?
The study of relationships among organisms and their environment
What is Ecology?
The means by which matter is cycled through the environment using biological, geological, and chemical processes.
What are biogeochemical cycles?
An ecological pyramid is a model that can show these three elements of an ecosystem.
What are the biomass, flow of energy, and total numbers of an ecosystem?
What is a model?
The change in an external environment that causes a reaction.
What is a response to stimuli?
The organisms and their non-living factors in an area.
What is an ecosystem?
The thin, rocky outer layer of the Earth's suface.
What is the geosphere?
A single feeding relationship pathway with several links.
What is a food chain?
When water evaporates directly from the leaf of a plant.
What is transpiration?
The regulation of internal conditions needed for life.
What is homeostasis?
Rabbits fall into this category of organisms on an ecological pyramid. They are consumers that only eat producers.
What is a primary consumers?
The thin layer of Earth that contains all living organisms
On average, only about this much energy is transferred from one trophic level to the next
What is 10%?
Organization, growth and development, and homeostasis are a few examples.
What are the characteristics of life?
The ability to evaluate scientific and medical information critically.
What is Scientific Literacy?
Fungi and other detritus-consuming organisms.
What are detritivores or decomposers?
The burning of fossil fuels is one example of this type of process in carbon cycling.
What is a human process?
What you get if you mathematically calculate the amount of energy transferred between two trophic levels on an ecological pyramid.
What is the trpohic efficiency?
What is an aerobic process?
The factor measured in an experiment?
What is a dependent variable?
Predation, competition and symbiosis are three examples of this ecological phenomenon.
What are community interactions?
These two processes are key in the cycling of carbon between the biosphere and the geosphere, atmosphere, and hydrosphere?
What are photosynthesis and cellular respiration?
What is the Net Primary Productivity of producers?
These bacteria take nitrogen and turn it into something plants can use
What are nitrogen-fixing bacteria?
