Final answer:
Amber is the correct answer to the question of which thick substances from trees trap and fossilize organisms. Other options like coprolites, nodules, and concretions are different forms that are not related to tree resins.
Step-by-step explanation:
The thick substances from trees that trap organisms and enclose them for fossilization refer to Amber. Amber is the fossilized tree resin that can capture a variety of organisms, such as flowers, insects, and small animals, preserving them for millions of years. Other options like coprolites, nodules, and concretions represent different forms of fossil or geological features not directly related to the organic trapping process of trees.
Coprolites are fossilized excrement which provides evidence of the feeding behavior and sometimes the internal anatomy of organisms. Nodules and concretions are hard, compact masses of matter formed by the precipitation of mineral cement within the spaces between particles, which can sometimes contain fossils or other organic matter, but they are not directly produced from tree substances.
