  yearly grass fires that often destroy the birds
  nesting trees. Which of the following best
  explains why this action would lead to either a
  short-term or long-term effect on the hyacinth
  macaw population?

  in turn, has cooled the stream flows to normal
  temperatures. Which of the following organisms

  bears has generally increased since 1978.
• C) The extent of Arctic sea ice each year
  depends on the size of the polar bear population.
• D) The polar bears survival is threatened
  because less sea ice makes it more difficult for
  them to hunt.
