The following figure is a model of seedling establishment as a function of distance from a parent tree. Initial seed density measures the number of seeds falling to the ground. Seed survivorship measures the proportion of seeds that survive to the adult stage at each distance

Which of the following factors is most likely to generate the seed survivorship curve shown?

#Unit 10. Ecological Principles

Seed predation is lowest far from the parent tree.
The best microhabitat for mutualistic seed dispersers is directly under the parent tree.
The best microhabitat for seedling growth is directly under the parent tree.
Many seeds reach the locations where they would have the highest probability of surviving to adulthood.
