  4. In Latin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • The term nomenclature means the scientific naming of organisms according to an established system. In earlier days common vernacular names were used which generally changes with change of language. Later in the haunt of one common internationally accepted name for a species, scientific names (Technical names) have been introduced in the form of polynomial, binomial and trinomial systems of nomenclature.
  • In the early seventeenth century, taxonomists started using a string of descriptive Latin words to designate a species. For example, in the herbal of Clusius (1583) a species of willow is named as Salix pumila angustifolia altera.
  • Polynomial nomenclature was discarded for the two main reasons that it was lengthy and difficult to remember, it often varies from place to place, scholar to scholar based on the characters chosen by them.
So the correct option is 'Cumbersome'.

  Organisms such as  plants that use light to make their own food are known as 

  1. Heterotrophs

  2. Photoautotrophs

  3. Symbionts

  4. Parasites

  5. Herbivores
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A. Heterotrophs are the organisms that feed on autotrophs or producers for their food.
B. Photoautotrophs are the organisms that use the light energy and convert it into chemical energy to make their food. For example, plants.
C. Symbionts are the organisms that form association with other organisms. The association may be commensalism, mutualism, parasitic etc.
D. Parasites are the organisms that live within or on an other organism which is called the host.
E. Herbivores are the primary consumers that feed directly on the producers (plants).
Hence organisms such as plants that use light to make their own food are known as photoautotrophs.
So, the correct answer is 'Photoautotrophs'.
