Lapatulllka [165]
I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:

You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled

50% will be rr (round)

Anit [1.1K]

Answer:

A source from which organisms generally take elements is called exchange pool (option B).

Explanation:

Options for this question are:

  • <em>Food web.</em>
  • <em>Exchange pool.</em>
  • <em>Reservoir.</em>
  • <em>Biotic community.</em>

The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.

<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.
