many birds live in mountainous temperate forest ecosystems. above the tree line on mountains, however, fewer birds are found. many factors contribute to the lower number of birds seen above a mountain’s tree line. which of these attributing factors is abiotic?\na. limited food\nb. no trees for shelter\nc. frequent high winds\nd. high - flying predators

Answer

Brief Explanations:

To determine the abiotic factor, we recall that abiotic factors are non - living components of an ecosystem.

  • Option A: Limited food is related to biotic components (as food sources are often living organisms or products of living organisms), so it is biotic.
  • Option B: No trees for shelter - trees are living organisms, so the lack of trees is related to biotic components (the presence/absence of a living thing), so it is biotic.
  • Option C: Frequent high winds - wind is a non - living component of the environment, so it is an abiotic factor.
  • Option D: High - flying predators - predators are living organisms, so this is a biotic factor.

Answer:

C. frequent high winds
