  • Monsoons blow across the water and the land, so
    these areas have wet and dry seasons
  • People add fish ladders to dams
    to reduce habitat destruction
  • What is a biblical approach for using natural resources?
    to find balance in the use of natural resources
  • in the carbon and oxygen cycles, what do plants need for photosynthesis
    water, carbon dioxide, and the sun's energy
  • What is one of the jobs of an aquatic ecologist?
    to study freshwater and saltwater ecosystems
  • if an area has spring, summer, and autumn, and winter seasons it_____________________
    changes in average temperature each year
  • decomposers release carbon dioxide gas into the atmosphere, so
    they are part of the cycles of matter and change
  • what makes up most of the earth's atmosphere
    nitrogen
  • natural and man-made stresses can cause what?
    many changes in a succession
  • The puffin population is increasing because
    laws regulating overhunting
  • Why did natural stresses come into the world?
    as a result of the fall
  • in the nitrogen cycle, how is nitrogen changed into nitrogen compounds
    some bacteria and lightning can change nitrogen into nitrogen compounds
  • if an area has wet and dry seasons, it
    changes in the amount of precipitation a lot
  • What is an endangered species?
    a species that is in danger of no longer existing
  • which earth system includes all of earth's water
    hydrosphere
  • What states of matter can precipitation fall as
    liquid and solid
  • what is it called when water vapor is released from plant leaves through the stomata
    transpiration
  • if an area has only summer and winter seasons it_______________________
    changes in average temperature each year
  • in the carbon and oxygen cycles, what is one difference between cellular respiration and photosynthesis
    cellular respiration adds carbon dioxide to the atmosphere. Photosynthesis removes it from the atmosphere
  • Why does the earth have regular cycles of change?
    Because God uses cycles to maintain His earth
  • during cellular respiration, what do cells use oxygen for
    to break down sugar into usable energy

    Nutrients are recycled from dead trees and other plants into the soil
  • Give one example of habitat destruction
    draining a wetland to build a new school
  • What is one of the causes of a wildfire?
    people's carelessness
  • Each step happens in a circular pattern, so
    the seasonal, water, carbon, oxygen, and nitrogen cycles are described as repeating
  • What is one way that floods and droughts are similar?
    They both can destroy crops and affect the topsoil
  • why are decomposers part of the nitrogen cycle
    because decomposers return nitrogen compounds back to the soil for plants
  • what is a succession in an ecosystem?
    a series of gradual changes in the populations of organisms in an ecosystem
  • What is an invasive organism?
    an organism that has been introduced to a new ecosystem and can cause harm
