○ What are the major principles of -Require ongoing inputs of energy and raw
living things? materials
-Sense and respond to change
-Pass DNA to offspring
, ■ What is the difference between a •Producers
producer and a consumer? -Make own food using energy and simple raw
materials from nonbiological sources
-Example: photosynthesis in plants
•Consumers
-Obtain energy and nutrients by feeding on other
organisms
-Example: mammals
homeostasis? -Process by which an organism keeps its internal
conditions within a range that favors survival by
sensing and responding to change
○ How does energy move within an one-way flow of energy through the biosphere and
ecosystem? Is heat a usable energy cycling of nutrients among organisms sustain life's
source? organization.
○ What is a nutrient? How do A substance that an organism must acquire from
nutrients move within an ecosystem? the environment to support growth and survival.
nutrients move in one-way cycle through
producers and consumers
○ What is the purpose of DNA? •DNA (deoxyribonucleic acid)
-Carries hereditary (AKA genetic) information that
guides development, growth, and reproduction
-Source of life's diversity
○ What are characteristics of the Archaea: Singular, archaeon. Group of prokary-
three Domains? otes that are more closely related to eukaryotes
than to bacteria.
Bacteria: Singular, bacterium. The largest, most
diverse and well-known group of prokaryotes
Eukarya: Organisms whose cells characteristically
have a nucleus (protists, fungi, plants, and animals).
