Rarefaction in terms of ecology can be defined as a technique used to assess species richness from the results of sampling.
It allows the calculation of richness of a particular species for a given number of individual samples, and these are based on the construction of rarefaction curves.
Hence, the correct answer is: option A-Creating a representative sample

Reproduction - The process which is used to create offspring similar to parents.
Excretion - The release of harmful substances from the body. We excrete carbon dioxide when we exhale.
Nutrition - Consumption of food for energy. We get nutrition by eating three meals a day.
To show the carbon cycle in a bottle ecosystem. A bottle ecosystem is to recreate an ecosystem inside a bottle or a container to study them or just for decoration. ... The second thing that happens in the ecosystem is that the pondweed absorbs the carbon dioxide converting it into oxygen by the process of photosynthesis.
