Bio Lab #1 Quiz
| Question | Answer |
|---|---|
| What is Acid Precipitation? | - any precipitation with a pH< 5.5 - Acid rain, fog, or dust |
| What is Acid Deposition? | - acid precipitation plus dry-particle fallout |
| How does burning fossil fuels result in acid deposition? | - It results into sulfur dioxide and nitrogen oxide to enter the atmosphere converting into acid. |
| What is anthropogenic? Examples? | - Pollution that is caused by Human - Pesticides, solvents, detergents |
| What is Biodiversity? | - It is the variety of life forms within a given ecosystem, biome, or on the entire planet. |
| What is Daphnia? | - a genus of small freshwater, water fleas, that are important the aquative ecosystems as prey and nutrient cycling |
| What is a dead zone? | - the occurence of fatally low oxygen conentrations in marine |
| What is detritus? | - is organic decomposing remains |
| What is Eutrophication? | -the process where primary production increases as an ecosystems changes from nutrient poor to nutrient rich |
| What is fossil fuels? | - non-renweable energy source like coal, oil and natural gas. |
| What does the burning of fossil fuels produce? | - carbon dioxide, sulfur dioxide, and nitrogen oxide whcih results in acid deposition |
| What is germination? | - a bioligcal process by a seed begining to grow/sprout |
| What is Grammarus? | |
| What is a limiting nutrient? | - essentail elements that is in short supplt that organisms and ecosystmes need thereby restrickting groweth reproduction, and productivity - like nitrogen and |
| QWhat is Nitrogen Fixation and its imporance? | - the process oif converting inert Nitrogen gas into ammonia that plants can absorb and use to build proteins, chlorophyll, and DNA |
| What is a Phytoplankton? | -primary produces in aquatic ecosystems like cyanobacteria, algae, and protist |
| What are Zooplankton? | -Primary consumers in aquatic systems like Rodifers that feed on phytoplankton -Heterotrophic protist |
| When an influx of nitrogen and phosphorus enter an aquatic systems, it can eventually lead to . . .? | - Eutrophication and a dead zone |
| The number of different species and realtive abundance in a defined area is called? | - Species richness |
| Whar are three types of aquatic pollution? | - Air pollution - Water pollution - Thermal pollution |
| Which compounds produce acid rain? | -Nitrogen oxides and sulfur dioxide |
| The pH in the oceans is also decreasing, due to increased levels of . . . | - carbon |
| What are two effects of the ocean acidification? | - low pH interferes with calcium carbonate shells |
| Does acid affect seed germination? | - Yes |
| The pollution produced when water is used to disperse waste hear? | - Thermal Pollution |
| Any substance that causes harm to the enviornment or humans is considered . . . ? | - Pollution |
| What would happen if the water became depleted of oxygen? | - Dead zone |
| TRUE or FALSE Sediments help to bring more nutrients into aquatic systems. | FALSE |
| TRUE or FALSE Point and non-point sources of pollution contribute to algal blooms and eturophication | TRUE |
| TRUE or FALSE The oxygen levels increase in warmer water | FALSE |
| TRUE or FALSE Seed germination is affected by pH levels in the soil. | TRUE |
| TRUE or FALSE Low pH interferes with productions of calcium carbonate shells. | TRUE |
| TRUE or FALSE High calcium levels contribute to acid rain | FALSE |
| For most human history, the major source of energy has been human muscles. | TRUE |
| Volcanoes are an important antropogenic source of carbon dioxide in the atmosphere. | FALSE |
