07. Main inputs of phosphorous as a nutrient in soil come from:

  1. Rainfall
  2. Phosphorous fixing bacteria
  3. Weathering of soil
  4. Atmospheric gas exchanges with soil

Select the correct answer using the codes below:

  • a. 
  • b. 
  • c. 
  • d. 
Answer : c

The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth.

08. Consider the following statements regarding the Ecotype:

  1. Ecotype of a species are always inter-fertile.

Which of the statements given above is/are correct?

  • a. 
  • b. 
  • c. 
  • d. 
Answer : d

In evolutionary ecology, an ecotype, sometimes called ecospecies, describes a genetically distinct geographic variety, population or race within a species, which is adapted to specific environmental conditions.

10. Consider the following definitions:

  1. Ecotone is a zone of transition between the two adjacent ecological communities.
  2. Ecads is a population of species belong to the same genetic stock but different in size and shape.
  3. Ecological niche is the role and position a species has in its environment.

Which of the definitions given above is/are correct?

  • a. 
  • b. 
  • c. 
  • d. 
Answer : d

Ecotone: An ecotone is a zone of junction or a transition area between two biomes [diverse ecosystems]. It is where two communities meet and integrate. For e.g. the mangrove forests represent an ecotone between marine and terrestrial ecosystem.

Ecad: These are also called epharmones or habitat forms which are environmentally induced variations. They belong to the same genetic stock or species and the variations in their morphology (in shape, size, number and reproductive capacity) are induced by the environmental influences.

Ecological Niche: Ecological Niche refers to the unique functional role and position of a species in its habitat or ecosystem.
