Question

Below are the lognormal distribution data that resulted from sampling marine animal guilds and phytoplankton communities in an expedition to Antarctica. What statement below is correct based on the lognormal distribution data below? Piscivorous birds Phytoplankton Pelagic Crustaceans Number of species Number of species Number of species Log (Number of Individuals) Log (Number of Individuals) Log (Number of Individuals) More rare species of pelagic crustaceans were found than rare species of piscivorous birds. The most sampling effort was used to sample phytoplankton, the least sampling effort was used to sample pelagic crustaceans. No rare species of phytoplankton were sampled No abundant species of piscivorous birds were sampled.

Answer 1

1. This statement is wrong because according to graph piscivorous birds has more rare species than pelagic crustaceans.

2. Since many plankton species were recorded, so it was difficult to observe them. This statement is right.

3. As we can see from the graph, many rare species of phytoplanktons were recorded with a very less number of individuals.

4. We can see many species with many individuals were recorded.
