Worked Solution & Example Answer:Answer either A or B - Scottish Highers Biology - Question 11 - 2018
Step 1
Write notes on components of biodiversity and how these are measured.
Answer
Biodiversity consists of three primary components: species diversity, genetic diversity, and ecosystem diversity.
-
Species Diversity: This is measured in terms of species richness and relative abundance.
- Species Richness: This refers to the number of different species present in a given area.
- Relative Abundance: This indicates how common or rare a species is relative to other species in the ecosystem.
-
Genetic Diversity: This is quantified by the number and frequency of different alleles within a population or species, highlighting the genetic variation that exists.
-
Ecosystem Diversity: This reflects the number of distinct ecosystems within a specific area or environment.
The measurement of biodiversity helps assess the health of ecosystems and can indicate the potential for resilience to changes.
