Biodiversity Conservation And Wild Life Question 4
Question: The proportionate number of individuals of different species in an area is called as:
Options:
A) Species diversity
B) Species richness
C) Diversity index
D) Species evenness
Show Answer
Answer:
Correct Answer: D
Solution:
The proportionate number of individuals of different species in an area is indeed referred to as D) Species evenness. Here’s why:
A) Species diversity: This term refers to the variety and abundance of different species within a particular region. It takes into account both species richness and species evenness, but it does not specifically refer to the proportionate number of individuals of different species.
B) Species richness: This term refers to the number of different species in a particular area. It does not take into account the proportionate number of individuals of each species.
C) Diversity index: This is a quantitative measure that reflects how many different types (such as species) there are in a dataset, and simultaneously takes into account how evenly the basic entities (such as individuals) are distributed among those types. The value of a diversity index increases both when the number of types increases and when evenness increases.
D) Species evenness: This term refers to how equal the community is numerically. So if there are 40 foxes, and 1000 dogs, this community is not very even. But if there are 500 foxes and 500 dogs, this community is quite even.
So, the correct answer is indeed D) Species evenness. It’s important to note that all these factors contribute to the overall biodiversity of an area, and they are all important considerations in conservation biology.
