Answer:

The correct answer is - freshwater snails.

Explanation:

Producers are organisms that produce their own food and not depends on any other organism by the process of photosynthesis such as algae. Primary organisms on the other hand directly depend on the producers for their food and often gt killed by secondary consumers.

Freshwater snails are the perfect example of the primary consumer as they get their food and energy from algae and are the primary source of food and energy for small fishes.

<h2>Calculate the Rf values</h2>

Explanation:

  • In the event that an alternate dissolvable were utilized, the Rf worth would not be the equivalent on the grounds that, contingent upon the dissolvable, there is a distinction in dissolvability. On the off chance that an alternate dissolvable was utilized, the general places of the groups would be different.
  • The Rf estimation of the xanthophyll is 66% that of carotene since xanthophyll has a H bond with cellulose, which backs it off, and makes it less dissolvable in the dissolvable.
  • Carotene is progressively dissolvable in 9:1 oil ether CH3)2CO arrangement, which made it be conveyed higher and have a bigger Rf value.
  • Measure the separation the dissolvable voyaged, which is Df, and measure the separation the test arrangement voyaged, which is Ds.
  • Ascertain the maintenance factor utilizing this condition <em>RF = Ds/Df. </em>
  • Basically isolate the separation the arrangement went by the separation the solvent traveled.
