Factoid 287 <ul><li>Tropical Rainforest (Near equator, South America) </li></ul><ul><li>Climate – year-around high temperatures; high rainfall </li></ul><ul><li>Dominant Plants – broad leaf evergreen trees, ferns, large variety. LOTS of diversity. </li></ul><ul><li>Dominant Animals – all types of animals in a large variety; most biodiversity. </li></ul>
  11. 11. Factoid 288 <ul><li>Rivers and steams </li></ul><ul><li>Freshwater; flowing water; may be fast or slow moving </li></ul><ul><li>Colder and cleaner than standing water. </li></ul>
  12. 12. Factoid 289 <ul><li>Lakes and Ponds </li></ul><ul><li>Freshwater; standing water; </li></ul><ul><li>Warmer and more turbid </li></ul>
  13. 13. Factoid 290 <ul><li>Aphotic zone </li></ul><ul><li>Deep in the water where it is dark and no sunlight reaches. </li></ul>
  14. 14. Factoid 291 <ul><li>Photic zone </li></ul><ul><li>Area of water where light does penetrate. </li></ul><ul><li>Lots of photosynthetic organism live here which attract other animals to this area. </li></ul>
  15. 15. Factoid 292 <ul><li>Costal ocean </li></ul><ul><li>Saltwater; area from the outer continental shelf to the low-tide mark </li></ul>
  16. 16. Factoid 293 <ul><li>Intertidal zone </li></ul><ul><li>Saltwater; area between low tide and high tide; subject to tidal changes </li></ul><ul><li>Organisms live here that can stand to be out of the water. </li></ul>
  17. 17. Factoid 294 <ul><li>Coral Reefs </li></ul><ul><li>Made of calcium carbonate formed by corals (cnidarians); warm saltwater; usually no deeper than 40 meters. </li></ul>
  18. 18. Factoid 295 <ul><li>Estuaries </li></ul><ul><li>Where freshwater rivers and streams merge with the oceans; varying salt concentrations </li></ul><ul><li>Brackish water </li></ul>
  19. 19. Factoid 296 <ul><li>A predator hunts, kills, and eats prey. Prey is what the predator eats. </li></ul>
  20. 20. Factoid 297 <ul><li>Competition results from two or more organisms trying to use the same resource. </li></ul><ul><li>Can include food, water, shelter, or even a a mate. </li></ul>
  21. 21. Factoid 298 <ul><li>Symbiosis is a relationship between organisms. </li></ul>
  22. 22. Factoid 299 <ul><li>Mutualism is a type of symbiotic relationship in which both organisms benefit from living together. </li></ul>
  23. 23. Factoid 300 <ul><li>Commensalism is a type of symbiosis in which one organism gets the benefit of the relationship and the other organism is neither benefited or harmed. </li></ul>
  24. 24. Factoid 301 <ul><li>Parasitism is a type of symbiosis in which one organism gets the benefit and the other member gets harmed. </li></ul><ul><li>Parasites weaken, but do not kill the host. </li></ul>
  25. 25. Factoid 302 <ul><li>The carrying capacity refers to the largest number of organisms of a species that can be supported by the environment. </li></ul>
  26. 26. Factoid 303 <ul><li>Population growth is limited by factors such as the birth/death rate, the number of organisms entering and leaving the population, and the amount of available resources. These are called limited factors. </li></ul>
  27. 27. Factoid 304 <ul><li>Ecological succession is a series of predictable changes in an ecosystem. </li></ul>
  28. 28. Factoid 305 <ul><li>Primary succession starts on the earth’s surface where there is no soil. Occurs after a major disturbance like a volcano eruption and all the soil is removed. </li></ul>
  29. 29. Factoid 306 <ul><li>Secondary succession occurs when plants have been removed leaving the soil. Secondary succession is the replacement of plant species in an area that has been disturbed. </li></ul>
  30. 30. Factoid 307 <ul><li>Typically in Mississippi succession happens in this order: </li></ul><ul><li>Grasses  weeds and wild flowers  shrubs  pine trees  hard wood trees </li></ul>
  31. 31. Factoid 308 <ul><li>When runoff from fields washes fertilizer into pond, algae can grow out of control. This is called algal bloom. </li></ul>
  32. 32. Factoid 309 <ul><li>When a poison is not excreted from the tissues of an organism, but build up in them instead, it is known as biological magnification. </li></ul>
  33. 33. Factoid 310 <ul><li>A natural resources can be classified as renewable or non-renewable resources. </li></ul><ul><li>Non-renewable resources (coal, oil, natural gas) take millions of years to form. </li></ul><ul><li>Renewable resources (water, trees) can be replaced quickly. </li></ul>
  34. 34. Factoid 311 <ul><li>If something is biodegradable, then it can be broken down quickly by microorganisms. </li></ul>
  35. 35. Factoid 312 <ul><li>Urban development refers to the destruction of natural areas for human use such as shopping malls and houses. </li></ul>
  36. 36. Factoid 313 <ul><li>The ozone layer protects the earth’s surface from harmful ultraviolet (UV) radiation. Some chemicals made used by humans can destroy ozone. Decreased ozone could be a cause for global warming. </li></ul>
  37. 37. Factoid 314 <ul><li>Global warming refers to the rise of global temperatures. Increased levels of carbon dioxide can increase global temperatures. </li></ul>
