Final answer:
Westoby, Leishman, and Lord's research indicates that plants like coconuts and chestnuts that have low fecundity produce the largest and most energy-rich seeds, enhancing their survival likelihood.
Step-by-step explanation:
Westoby, Leishman, and Lord found that plants with low fecundity, such as coconuts and chestnuts, produce the largest seeds.
These energy-rich seeds each have a good chance to germinate into a new organism.
Contrastingly, plants with high fecundity, like orchids, produce many small, energy-poor seeds that have a relatively poor chance of surviving.
However, the energy trade-off is also effective as it is a matter of where the energy is allocated, whether for large numbers of seeds or fewer seeds with more substantial energy reserves to achieve self-sufficiency.
