| Question | Answer |
| Define Ecology | the study of the interactions between living and non-living things. |
| Define Population | a group of interbreeding organisms coexisting together |
| Define Community | a group of populations living and interacting in the same area |
| Define Ecosystem | an association of living organisms and their physical environment |
| Define Biome | a group of ecosystems classified by climate and plant life |
| Define Primary Consumers | an organism that eats producers |
| Define Secondary Consumers | an organism that eats primary consumers |
| Define Tertiary Consumers | an organism that eats secondary consumers |
| Define Ecological Pyramid | a diagram that shows the biomass of organisms at each trophic level |
| Define Biomass | a measure of the total dry mass of organisms within a particular region |
| Define Transpiration | evaporation of water from the leaves of a plant |
| Define Watershed | an ecosystem where all water runoff drains into a single body of water |
| Define Greenhouse Effect | the process by which certain gases trap heat that would otherwise escape the earth and radiate into space |
| When fruits and vegetables are important into the U.S. from a foreign country, they are always very closely inspected for insects, even though the majority of the insects are not really harmful. Why is the inspection done? | because it can ruin the balance of the ecosystem |
| Which two trophic levels have the greatest disparity in biomass? | primary consumers and secondary consumers |
| Between two trophic levels is the smallest amount of energy wasted? | producer and primary consumers |
| Name the participants in the three new symbiotic relationships that we learned in this module. | Clownfish and Sea Anemone, Oriental Sweet-lips and blue-streaked wrasse, and Blind Shrimp and Goby |
| What fundamental assumption of macroevolution does mutualism seem to contradict? | they struggle for survival |
| Why doesn't the ocean lose water? | because the excess water from land runs into the ocean |
| What does the water cycle accomplish besides balancing the water in an ecosystem? | it transports the nutrients |
| What is the possible consequence if deforestation occurs in a watershed? | too many nutrients would flow into the water, causing the ecosystem to become off balance |
| What is the principal means by which oxygen is taken from the air? What is the principal means it is restored to the air? | respiration; photosynthesis |
| Name the other ways that oxygen is removed from the air. | ozone formation, rusting of metals and mineral, and fire |
| Name the other ways that oxygen is replenished in the air. | ozone destruction and water vapor destruction |
| Name the ways carbon dioxide is removed from the air. | dissolving into the ocean and photosynthesis |
| Name the ways in which carbon dioxide is replenished in the air. | fuel burning, fire, respiration, and decomposition |
| What human activity worries those who think that global warming is a problem? | Burning fuel |
| Is human-produced global warming occurring now? | No |
| What is nitrogen-fixation? What type of organisms perform it? | It converts nitrogen gas into chemically active molecules that many organisms can use; nitrogen-fixing bacteria |
| What two ways does that nitrogen in organisms get put back in to the environment? | Waste and Decomposition |
