Intro to Biology
The study of living things
What is Biology?
A body of knowledge based on the study of nature
What is science?
A factor that remains fixed during an experiment while the independent and dependent variables change
What is a constant?
The study of organisms and their interactions in their environments
What is Ecology?
An organism that gets energy by consuming other organisms
What is a heterotroph?
Anything that has or once had the characteristics of life
What is an organism?
A set of values
What are ethics?
A group not receiving the factor being tested
What is the control group?
The biological community and all the abiotic factors that affect it
What is an ecosystem?
A heterotroph that eats only plants
What is an herbivore?
A group of organisms that can interbreed and produce fertile offspring
What is a species?
An explanation of a natural phenomenon based on many observations and investigations over time
What is a theory?
A testable explanation of a situation
What is a hypothesis?
The portion of Earth that supports life
What is the biosphere?
A model that shows how energy flows through an ecosystem
What is a food chain?
Inherited characteristics of a species that develops over time in response to an environmental factor, enabling the species to survive
What is an adaptation?
A description of a relationship under certain conditions in nature
What is a law?
Quantitative or qualitative information gained from scientific investigation
What is data?
The living factors in an organism's environment
What is biotic?
A model representing the many interconnected food chains and pathways in which energy flows through a group of organisms
What is a food web?
The regulation of an organism's internal environment to maintain the conditions needed for life
What is homeostasis?
A process in which procedures used during an experiment can be repeated and the results are evaluated by scientists who are in the same field or are conducting similar research
What is peer review?
A series of problem solving procedures that may include observations, forming a hypothesis, experimenting, gathering and analyzing data, and drawing conclusions
What is the scientific method?
The nonliving factors in an organism's environment
What is abiotic?
Organisms that eat fragments of dead matter in an ecosystem
What are a detritivores?
