The principle of faunal succession states that if we can estimate the age of the fossils, we can

find the absolute age of a fossil.

assume that the rock layer formed at the same time the fossil formed.

older fossils will be found below younger fossils.

use extinct animals to guide the principle of faunal succession.

when it is at an intermediate population density

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
