What would happen to the population estimate if animals that were marked tended to move out of the catchable population (deeper water for fish) or into an adjacent habitat for other animals?
what would happen to the population estimate if marked animals were either less likely to be captured in the second sample (e. g., fish avoid the boat after being handled) or more likely to be captured in the second sample (e. g., mice return to a trap because they know there is food there)?

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.

true. until louis pasteur developed the rabies vaccine, “vaccines” had referred only to the cowpox inoculation for smallpox. hope this : )
