  2. Why do ecosystems not need a constant supply of matter? • Because matter is constantly recycled

  3. How do organic compounds differ from inorganic compounds? • All organic compounds contain Carbon

  4. What is the land called that drains water into tributaries? • Watershed

  5. What is the source of energy in a food web? • The Sun

  6. What can cause erosion to occur? • Wind • Water • Ice

  7. What other catastrophic events could occur from a volcano? • Landslide • Earthquake • Wildfire

  8. When identifying an organism using a dichotomous key, how many choices should be with each step? • Two

  9. How is energy transferred during photosynthesis? • Radiant energy is transformed into chemical energy.

  10. What are examples of tropisms – things plants will respond to? • Gravitropism (Geotropism) – response to gravity • Phototropism – response to light • Thermotropism – response to temperature

  11. What does a secondary consumer eat? • Omnivore/Carnivore- eat animals • A primary consumer which eats only plants – A herbivore

  12. What is the order of ecological organization beginning with organism? • Organism, population, community, ecosystem, biosphere

  13. What is the pioneer species in primary succession? • Lichens

  14. What belongs in the energy pyramid? • A = producers • B = primary consumers • C = secondary consumers • A = 100% autotrophs • B = 10% herbivores • C = 1% carnivores C B A

  15. In a food web, what do plants provide for the consumers? • Energy

  16. When an animal eats a plant, what happens to the sugar? • The chemical energy gets converted into others forms of energy

  17. What do Fungi and bacteria have in common? • They recycle dead organic material

  18. What is the smallest level of ecological organization? • Organism – an individual member of a species

  19. What color fur will allow a rabbit to survive in an Arctic climate and why? • White fur – so it can hide from predators

  20. How do most birds react to seasonal change? • They Migrate

  21. If dark moths have an advantage in hiding from predators what makes them most FIT? • Coloration • They have a better chance of surviving to produce dark-colored offspring and dark moths will become more abundant.

  22. What type of water will not affect oceans after a rain? • Groundwater – this water seeps into the ground and gets stored in aquifers.

  23. What is most likely to grow on bare rock after a volcanic eruption? • Lichens

  24. Having more species in an area will result in? • More links in food chains and more stability

  25. Having a variety of ecosystems would lead to? • More habitats for different species

  26. If organisms have two parents, what could you say about the offspring? • It is a mixture of two parents • ½ genes come from each parent • They exhibit traits from both parents • Leads to more diversity

  27. What adaptations would you find in a predator? • Sharp claws • Sharp pointed teeth • Small eyes

  28. If a brown rat and a white rat have only brown babies what are the most likely genotypes of the parents? • GG x gg

  29. What restricts the exploration of our solar system the most.? • The cost

  30. If GgxGg cross what percent is likely to be white? • 25 percent

  31. What is found within a chromosome and has information about particular hereditary traits? • Genes

  32. If a father has blonde hair and mother has brown, what are the possible hair color of the children? • Blonde or brown

  33. What characteristics allow life to live on Earth? • The presence of water • Proximity to the sun • Composition and existence of an atmosphere
