Worked Solution & Example Answer:Mass extinction events 1 - VCE - SSCE Biology - Question 23 - 2021 - Paper 1
Step 1
1. allow new species to evolve to occupy available niches.
Answer
Mass extinction events often result in the creation of new ecological niches that were previously occupied by the dominant species. This opportunity allows for adaptive radiation, where new species evolve to exploit these available resources and habitats.
Step 2
2. allow all species that survive to recover and diverge.
Answer
While some species may recover after a mass extinction, it is not guaranteed that all surviving species will diversify. The recovery and diversification depend on various ecological factors, including competition and environmental changes.
Step 3
3. result from a constant global climate.
Answer
Mass extinction events are typically associated with significant changes in the environment, such as climate change, rather than a constant global climate. These changes often include severe fluctuations in temperature, sea levels, or atmospheric conditions.
