Question

if you wanted to study climate change, which fossil would be most useful? a fossil of an organism that is

o small, hard, abundant, sensitive to temperature change, and easily preserved

o large and difficult to find, but resistant to temperature change

o large and difficult to find, but sensitive to temperature change

o small, hard, abundant, resistant to temperature change, and easily preserved

Explanation:

To study climate change, a fossil that is small (easy to handle and analyze in large numbers), hard (resistant to physical damage during fossilization and study), abundant (allows for a large sample size to draw reliable conclusions), sensitive to temperature change (can show how climate/temperature affected its existence/characteristics), and easily preserved (ensures its availability for study over time) is ideal. A large and difficult - to - find fossil would limit the sample size. A fossil resistant to temperature change would not show the effects of climate change well.

Answer:

small, hard, abundant, sensitive to temperature change, and easily preserved
