Question
What are the two spatial patterns in an ecosystem? Describe them briefly.
✓

Answer

  1. There are two spatial patterns recognized in an ecosystem, viz. zonation and stratification.
  2. Zonation is the spatial pattern which occurs horizontally along the ground. Along a horizontal gradient, the density and distribution of the species keep on varying.
  3. Stratification is the spatial pattern which occurs vertically. This is determined by the height of organisms. Such stratification is seen in forest community where trees of different species grow to different heights.
