  14. binomial nomenclature combines            and species
  15. what is a phylogenetic tree is the tree of life
  16. are the organisms on the tips of the branches older or younger species the tips of the trees contain the youngest species and get older the closer into the truck it gets
  17. How is a biological key used is use organizing classify things and put them into families
  18. where the two characteristics used to distinguish sharks from each other thin and gills
  19. according to Darwin white is competition exist constituted exist to get rid of the weakest species so only the strong survive

  23. where are there more producers than consumers and the environment When the producer is eaten by the consumer, it is an exchange of energy. Ironically, 90% of the energy that the producer had is lost, and the consumer only receives 10% of it. Therefore, to get enough energy to survive, the consumer must eat more producers, meaning that, to sustain the consumers, there must me many more producers.

  26. During photosynthesis plants take up carbon dioxide from the atmosphere describe two ways a carbon dioxide is released back into the atmosphere plants use carbon and it makes up organic matter which is part of all life during photosynthesis plants and other producers transform carbon dioxide and release `into the atmosphere as they turned back into organic matter
  27. Which  biome diverse and why the rain forest is the most diverse because of all the rain and sun receives with very little human interaction
  28. Briefly describe the the chaparral is a plant that takes up 5% of the state of California and is very hardy
  29. how do mutualism and commensalisms differ mutualism is when two organisms need each other and commensalisms is when an organism is not harmed when another one uses it sometimes they don't even notice
