Auditory and Visual Methods of Communication in Survival Strategies

This test review compares and contrasts auditory and visual methods of communication among organisms, exploring their relation to the survival strategies of populations. It also includes a test autopsy analysis and discussion questions. Additionally, it provides an introduction to biomes and discusses freshwater ecosystems, marine ecosystems, tundra, taiga, temperate rainforests, temperate deciduous forests, grasslands, and savannas.

  1. LS.2.7,4,5,6 Compare and contrast auditory and visual methods of

  2. Test questions/ Test review WRITE THE QUESTION AND ANSWER IN YOUR COMP BOOK: • Which of the following best describes the relationship between the elk and wolf populations according to the graph? • If there are 2,500 units of energy available at the bottom of an energy pyramid, how much energy is going to be transferred to the primary consumers? • If a spider hides in an orchid flower and captures insects as it enters the flower, how is this an example of mutualism? • What is the reason predator/prey relationships are not symbiotic?

  3. Test Autopsy/ DiscussionQuestions to be turned in to Mrs. Weaver • Complete the test autopsy/ analysis using your notes. • Write a full explanation of why you missed the question. • Explain the CORRECT answer using vocabulary from the unit!!! • Wait for Mrs. Weaver to initial your autopsy. • Turn in autopsy to the basket. • BEGIN IXL!!!!

  4. ASSIGNMENT: AFTER THE TEST, PLEASE COMPLETE THE GRAPHIC ORGANIZER… • AUDITORY VS. VISUAL COMMUNICATION • EXAMPLES: • 1. • 2. • 3. • 4. • 5.

  5. Communication- Auditory and Visual • https://youtu.be/1kbZ1JAoi5o • Graphic organizer- Visual and Auditory Compare and contrast auditory and visual methods of communication among organisms in relation to survival strategies of a population.

  6. INTRODUCUTION TO BIOMES!!!! • https://youtu.be/0fb8143ndo8 TYPES OF BIOMES

  7. BIOME CLASSIFICATION • https://www.wartgames.com/themes/science/biomes.html • Biome • A large, relatively distinct terrestrial region with a similar climate soil, plants, and animals, regardless of where it occurs in the world • Ten major biomes • Location of each biome is primarily determined by: • Temperature (varies with both latitude and elevation) • Precipitation • Biomes can also be defined by • Winds, rapid temperature changes, fires, floods, etc.

  8. FRESHWATER ECOSYSTEMS/ BIOMES • Characterized by salt water concentrations less than 1% • Includes: • Rivers and streams • Lakes and ponds • Marshes and swamps • Represent 2% of earth’s surface • Assist in recycling water back to the oceans (Biogeochemical Cycling)

  9. Marine Ecosystems • Subdivided into life zones • Intertidal zone • Benthic zone • Pelagic environment • Neritic Province • Oceanic Province

  10. Human Impacts on the Ocean

  11. Human Impact on Coral Reefs • Sedimentation • From clear-cutting upstream • Overfishing • Coral bleaching • Mining of corals as building materials • Runoff pollution www.marinebiology.org

  12. Tundra • Treeless biome in the far north with harsh, cold winters and extremely short summers • Precipitation • 10-25 cm/yr • Temperature • Short growing season • 50-160 days

  13. Tundra • Nutrient poor soils with little organic material • Permafrost present • Low species richness • Vegetation is mostly grasses and sedges • Very simple food web • Low primary productivity

  14. Taiga/ Coniferous Forests • A region of coniferous forests in the northern hemisphere • Just south of tundra • Covers 11% of earth’s land • Growing Season • A little longer than tundra • Precipitation • ~ 50 cm/yr

  15. Taiga/ Coniferous Forests • Soils are acidic and mineral poor • Vegetation comprised of drought resistant conifers • Mostly small animals and migrating birds • Some large animals are present • Wolves, bear, moose

  16. Temperate Rainforest • Coniferous biome with cool weather, dense fog and high precipitation • Ex: Northwest US • Precipitation • > 127 cm/yr • Heaviest in winter • Temperature • Winters are mild • Summers are cool

  17. Temperate Rainforest • Soils are nutrient-poor, but high in organic material (dropped needles) • Cool temperatures slow decomposition • Dominant Vegetation • Large evergreen trees • Old-growth forest • Variety of cool climate animal life • Very high species richness • Heavily logged

  18. Us! Temperature Deciduous Forests • Forest biome that occurs in temperate areas with a moderate amount of precipitation • Precipitation • 75-150 cm/yr • Temperature • Seasonality • Hot summers and cold winters

  19. Temperate Deciduous Forest • Topsoil is rich in organic material and underlain by clay • Vegetation is primarily deciduous • Oak, maple, beech • Animals • Deer, bear and small animals • Most of this biome land area has been regenerated after farming & timber harvest

  20. Grassland • Grasslands with hot summers, cold winters and too little precipitation to support trees • Precipitation • 25-75 cm/yr • Tall grass prairies • Short grass prairies • 90% of this biome has been lost to farmland

  21. Grassland • Soil has thick, organic material rich organic horizon. • Periodic fires keep the dominant vegetation grasses • Animals • Once covered with bison- no longer true( because of hunting) • Smaller animals are still present (ex: prairie dogs)

  22. Savanna/ Tropical Grassland • Tropical grassland with widely scattered trees • Temperature • Varies little throughout the year • Precipitation • Seasons regulated by precipitation, not temperature • 76-150 cm/yr

  23. Savanna/ Tropical Grassland • Soil low in nutrients due to leaching • Vegetation • Wide expanses of grass • Occasional Acacia trees • Have fire adaptive characteristics • Animals • Herds of hoofed animals • Large predators- lions, hyenas, etc.

  24. Tropical Rainforest • Lush, species-rich biome that occurs where climate is warm and moist throughout the year • Precipitation • 200-450 cm/yr • Very productive biome • Most species-rich biome

  25. Tropical Rainforest • Ancient, weathered, nutrient-poor soil • Nutrients tied up in vegetation, not soil • Vegetation • 3 distinct canopy layers • Animals • Most abundant insect, reptiles and amphibians on earth

  26. Biome where lack of precipitation limits plant growth Temperature Can vary greatly in 24-hr period, as well as yearly (based on location) Precipitation < 25 cm/yr DESERTS

  27. Deserts Soils low in nutrients, high in salts Vegetation sparse      -Cactus and Sagebrush Animals are very small to regulate temperature

  28. CANADA USA MEXICO Biomes of North America Make sure to color your map according to directions. Fill in the key with the appropriate color!

  29. WORLD BIOME MAP- GROUP ACTIVITY • In your table groups, get an envelope from your desk. • Open the envelope and follow directions. • Color code the corresponding map with the correct colors...LABEL THE PROPER BIOME! • After you have finished, wait for the timer to switch tables.
