Which among the following statements correctly differentiate between an Ecozone and a Biome?
1.An Ecozone comprises only land parts of Earth surface, while the Biomes comprise both aquatic and land parts
2.Each Ecozone has some finite number of species , while each biome has infinite number of species
3.Ecozone is a larger ecosystem, biome is a group of ecosystems
Which among the above statements is/ are correct?

Answer: [A] Only 1 is correct


Ecozones are the Biogeographic division of the Earth’s land surface, based on distributional patterns of terrestrial organisms. This means that they include ONLY terrestrial part of the Biosphere and that is why they are alternatively called “Terrestrial Ecozones”. Further, Ecozones are defined by genetic, taxonomic, or Geological similarities, rather than the Morphology, plant structures, leaf types, plant spacing or climates. Then, an Ecozone can include a number of different biomes. They both are groups of ecosystems.
