Consider the following pairs:

  1. Halosere→ succession in a saline environment
  2. Psammosere→ succession in sand
  3. Xerosere→ succession in dry area

Which of the above is/are correct?

Answer: [D] 1, 2 & 3

Halosere is a succession in a saline environment. An example of a halosere is a salt marsh. Psammosere is an ecological succession that began life on newly exposed coastal sand. Sand dune systems are best examples of it. Xerosere is a plant succession that is limited by water availability such as salt deserts, rock deserts etc.
