  1. Science 7 Chapter 1 : Review “The Big Picture: Levels of Life”

  2. Check Your Understanding – pg. 32 • a) hydrosphere • lithosphere • atmosphere • biosphere • extinct • habitat

  3. Chapter 1 Review – pgs. 34-35 1. biosphere biome ecosystem community population individual

  4. a) biotic- living things in the environment abiotic- non-living things in the environment. • abiotic- non-living things in the environment. extinct- a species that has completely died out.

  5. c) individual- one organism population- A group of individuals of the same species, living together in one place. • weather- refers to local conditions that change from day to day, and even from hour to hour. climate- refers to the average weather pattern of a region.

  6. 5. natural non-living things a) rock b) water non-living things created by people a) car b) straw

  7. living things that interact: a) tree-squirrel – tree provides home for squirrel b) deer-grass- deer eats grass • biotic-abiotic interactions a) bear-sun – sun gives warmth to the bear b) flower-water- water provides food for flower so it can grow.

  8. -ability to fly to get in the tree - claws to latch/perch onto branches b) polar bear- fur to keep it warm, claws to catch prey, large lung capacity for staying under water for extended periods, white fur for camouflage.

  9. population- A group of individuals of the same species, living together in one place. example- 4 puppies community- is made up of all the populations that live in one area. example- group of trees, 3 birds, 2 deer

  10. ecosystem- is the interactions between abiotic features of an area and the biotic community that lives in the area. example: school ecosystem, backyard ecosystem, and swamp ecosystem 17. flippers- to help them swim better/ b) We are not born with these types of footwear.
