Worked Solution & Example Answer:The list describes some aspects of biodiversity - Scottish Highers Biology - Question 25 - 2019
Step 1
Identify components of species diversity
Answer
Species diversity typically refers to the variety of different species within a given ecosystem, which includes both the number of species and their relative abundance.
- The number and frequency of different alleles in a species: This refers to genetic diversity within a species, not species diversity itself. Therefore, this component does not directly relate to species diversity.
- The proportion of each species in an ecosystem: This indicates how abundant each species is relative to others in the ecosystem, which is a key component of species diversity.
- The number of different species in an ecosystem: This directly relates to the definition of species diversity as it quantifies the variety of species present.
From this analysis, the applicable components of species diversity are 2 and 3 only.
