Question

State the bases of classifying plants and animals into different categories

Answer 1

on the basis of living and non living on the basis of biotic and abiotic

Answer 2

Answer :

$CLASSIFICATION$ - Method of grouping the living organisms on the basis of similarities and differences and arranging these groups systematically into closely retaled orders is called Classification.

$BASIS\:OF\: CLASSIFYING\:PLANTS\:AND\:ANIMALS\:INTO\:DIFFERENT\:CATEGORIES$

1. $Complexity\:of\:Cell\: Structure$ : The living world is divided into two subkingdoms -
(a) Prokaryota - It is having prokaryotic cells.
(b) Eukaryota - It is formed of eukaryotic cells.
Prokaryota is also called Monera.It includes Bacteria, Mycoplasma and Cyanobacteria (Blue - green algae).

2. $Complexity\:of\:body\: Structure$ : Eukaryotic organisms are two types :
(a) Unicellular Eukaryotes or Protista.
(b) Multicellular Eukaryotes.

3. $Mode\:of\:Nutrition$ : Multicellular Eukaryotes are divided into three kingdoms :
kingdom PLANTAE with phototrophic nutrition; kingdom ANIMALIA with haterotrophic nutrition and kingdom FUNGI with saprophtic nutrition.

4. $Trophic\:Level$ : All eukaryotes are also classified as :
(a) PRODUCERS - These are all green plants thst synthesis food from CO2 and H2O by the process of photosynthesis using solar energy.
(b) CONSUMERS - These are all animals which feed on plants or their parts,i.e., have heterotrophic nutrition.
(c) DECOMPOSERS - These are fungi and bacteria that feed an organic remains.

5. $Organisation$ : Based on the complexity of body organisation, body design,morphological,physiological and genetic relationships,plants and animals are further classified into subphyla,class,order and so on.
