19 WGU C190 Learning Objectives Complete Study 1.Classify items as biotic (living) or abiotic (nonliving): Biotic: Living or having lived -Bacteria -Cotton -Yogurt
Abiotic: Nonliving and never having been alivebiome
-Water -Glucose -Carbon Dioxide -Cold Virus
2.Describe homeostasis: The ability or tendency of organisms and cells
to main- tain stable internal conditions.
3.Identify the levels of biological organization from atom to biome: -Atom
-Molecule -Cell -Tissue -Organ -Organ System 1 / 3
- /
19 -Organism -Population -Community -Ecosystem -Biome -Biosphere
4.Describe how energy flows through an ecosystem: Energy flows
through living systems changing forms as it goes.The energy in sunlight is captured by green plants, which use this energy to build sugar molecules.The energy from the sun is stored in the sugar and used to do work.Energy flows through the system; it is never recycled.
5.Describe how matter cycles through an ecosystem: Matter cycles within
living things.The atoms in the sugar molecule start out as nutrients and will ultimately become waste which can become nutrients for something else.The atoms will be used over and over again.
6.Compare and contrast types of interactions and relationships between 2 / 3
- /
19 species within a community: -Predation: Usually involves predator killing and eating prey. Also includes more subtle type of win-lose interactions.
-Competition: Lose-lose interactions. May involve two species interfering
directly (fighting) or using the same limiting resource.
-Parasitism: May involve animal or plant hosts that provide habitat and
food to their harmful symbionts.
-Mutualism: Win-win interactions. May involve species trading materials
services, or both.
-Commensalism: Two species may also engage in a symbiotic relationship
in which one species benefits and the other does not but also is not harmed.
7.Analyze the process of natural selection and its relationship to
evolution at the population level: Nature selects those individuals who
are best fit for the environment.If you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.Evolution is the scientific theory that explains how and why life changes over time.
8.Apply the process of scientific inquiry to questions about the natural world- : The term natural in this context means all that can be observed with our
