Bio Ecology Quiz
| Question | Answer |
|---|---|
| What are the levels of organization? | Cell, tissue, organ, organ system, organism, population, community, ecosystem, biome, biosphere |
| What is an organism? | One individual plant, animal, or single cell life form |
| What is a population? | A group of individuals of the same species living in the same place at the same time |
| What is a community? | A group of populations of different species |
| What is an ecosystem? | A community with its biotic and abiotic factors |
| What is a biome? | Several communities with climate |
| What is a biosphere? | The global ecological system integrating all ecosystems, their relationships |
| What defines a tropical rain forest? | Tall trees and a thick canopy, most species of any biomes |
| What defines a tropical dry forest? | Rain and dry seasons, plants have layer to reduce water loss |
| What defines a savanna? | Grassy areas, isolated trees and shrubs, acidic clay |
| What defines a desert? | Very low precipitation, very hot to very cold temperatures |
| What defines a temperate grassland? | Plains with prairies, fertile soil, no trees, grazing herbivores, fire-proof plants |
| What defines a temperate shrubland/chaparral? | Large areas of grass interspersed with oak and trees, plants have flammable oils and some needs fire for seeds to germinate |
| What defines a temperate forest? | Coniferous trees, soils rich with humus |
| What defines a northwest coniferous forest? | Tall coniferous trees, mild temperatures |
| What defines a taiga/boreal forest? | Dense forests, long winters, wax-covered needlelike leaves |
| What defines a tundra? | Permafrost (layer of frozen soil), short and soggy summers |
| What can take energy from any organism? | Decomposers |
| What are the types of consumers (6 types)? | Carnivores, herbivores, omnivores, decomposers, scavengers, detritivores |
| What are carnivores? | Only kill and eat other animals |
| What are herbivores? | Only eat plants |
| What are omnivores? | Eat plants and animals |
| What are decomposers? | Chemically break down organic matter |
| What are scavengers? | Consume the carcasses of other dead animals |
| What are detritivores? | Feed on detritus (small pieces of leftover carcass after scavengers) |
| What is a food web? | A web of interconnected food chains |
| What is a food chain? | The single, linear path flow of energy |
| What do pyramids of biomass show? | The relative amount of organic matter available at each trophic level |
| What do pyramids of numbers show? | The relative number of individual organisms at each trophic level |
| What do energy pyramids show? | The flow of energy between the trophic levels |
| What does the 10% rule of energy say? | Only 10% of energy is passed between trophic levels |
| What are the trophic levels of an energy pyramid? | Producers, primary consumers, secondary consumers, tertiary consumers, quaternary consumers |
| Where does energy go based on the 10% rule? | (#1) Cellular respiration, not all food at each level is eaten, not all food is digestible, waste biomass |
| What are the levels of the open ocean? | Photic, aphotic, abysal zone |
| What is the photic zone of the open ocean? | Top surface of the ocean where the most photosynthesis occurs, with low nutrients and small species of phytoplankton |
| What is the aphotic zone of the open ocean? | Deeper part of the ocean that is permanently dark, no photosynthesis pressure/cold temperatures, zooplankton |
| What does the line represent in climatographs? | Temperature |
| What do the bars represent in climatographs? | Precipitation |
| What is the difference between photosynthesis and chemosynthesis? | Photosynthesis uses light to convert CO2 and water in to O2 and glucose, while chemosynthesis (used by bacteria) uses chemical energy from hydrogen sulfide |
| What do fish and shellfish use as breeding and nursery grounds? | Estuaries |
| How are estuaries different from other marine ecosystems? | The water has some salinity but not as much as the ocean because they are the point where rivers meet oceans |
| What part of the ocean is the open ocean? | Pelagic zone |
| What is the abysal zone? | Deepest part of ocean, chemosynthesis occurs |
| What are the marine ecosystems? | Intertidal zone, coastal zone (coral reefs, kelp forests) |
| What are the freshwater ecosystems? | Estuaries, rivers/streams, lakes/ponds, wetlands |
| Why are wetlands important? | Hurricane surges, flood control |
| Which type of pyramid cannot be made upside down? | Energy pyramid |
| Where does all energy come from? | Sun |
