question 2 (5 points)

a population of sea life was very successful in its marine environment. suddenly, this sea life experienced a rapid decrease in population and ultimately, extinction. which of the following processes most likely led to this extinction?

Explanation:

For Question 1, the principle of inclusions states that rock - fragments (inclusions) in sedimentary layers are older than the surrounding sediments. For Question 2, a rapid environmental change can cause a sudden decrease and extinction in a population that was previously successful as it may not be able to adapt quickly enough.

Answer:

Question 1: B. Principle of inclusions
Question 2: A rapid environmental change (not given as an option in the provided text but the most likely cause based on general knowledge; if there were options like climate change, habitat loss etc. related to environmental change, that would be the correct pick among them).
