Correct option is B
Correct Answer
(b) Most species are rare and few species are common, represented by a large number of individuals
Explanation
The histogram shows a classic right-skewed species abundance distribution, where many species are represented by very few individuals, while only a small number of species have high individual counts. This pattern is typical of natural ecological communities, indicating rarity is common and dominance is limited to a few species.
Information Booster
• Natural communities usually show uneven species abundance patterns
• A few dominant species contribute disproportionately to total individuals
• Most species exist at low population sizes
• Such patterns are described by log-normal or hollow-curve distributions
Additional Knowledge
Option (a) is incorrect because most species do not have high individual numbers. Option (c) reverses the observed pattern of rarity and commonness. Option (d) is incorrect because ecological communities rarely show equal representation of species; evenness is generally low in species-rich systems.
