Question

Select the odd one w.r.t. criteria considered by
R.H. Whittaker to classify organisms.
(1) Thallus organisation (2) Phylogeny
(3) Locomotion (4) Mode of nutrition...

please answeranswer this
..​

Answer 1

Explanation:

Mode of nutrition is right answer because some organisms make their own food (autographs) while some are dependent on others(heterotrophs).

Hope it helps you

Answer 2

Answer:

Locomotion is not the criteria considered by R.H Whittaker to classify organisms.

Explanation:

In 1969, R.H. Whittaker proposed the five-kingdom division. Certain characteristics, including mode of nutrition, thallus organisation, cell structure, evolutionary relationships, and reproduction, served as the basis for this classification.

1. Cell structure: On the basis of cell structure, living organisms can be categorised into two main groups:

• prokaryotic (cells devoid of a well-organized nucleus and other membrane-bound organelles)
• Eukaryotes ( cells having well-organized nucleus and other organelles)

2. The complexity of an organism can be classified as either

• multicellular
• unicellular ( organisms consisting of more than one cell in their body)

3. There are two categories of organisms based on their mode of nutrition:

• autotrophic, or those that can produce their own food by using either chemical compounds or light (phototrophs) (chemotrophs).
• Hetrotrophic, or dependent on plants or other animals for nourishment because they are unable to produce their own food.

4. Phylogenetic relationship: Phylogeny is the study of an organism's evolutionary development. This characteristic demonstrates how organisms have evolved over time.

5. The ecological role of organisms was also taken into account, and producers, consumers, and decomposers were established.
