Answer 1

1. Competition for resources has long been considered a prevalent force in structuring plant
communities and natural selection, yet our understanding of the mechanisms that underlie
resource competition is still developing.
2. The complexity of resource competition is derived not only from the variability of resource
limitation in space and time and among species, but also from the complexity of the resources
themselves. Nutrients, water and light each differ in their properties, which generates unique
ways that plants compete for these resources.
3. Here, we discuss the roles of supply pre-emption and availability reduction in competition
for the three resources when supplied evenly in space and time. Plants compete for nutrients
by pre-empting nutrient supplies from coming into contact with neighbours, which requires
maximizing root length. Although water is also a soil resource, competition for water is gener-
ally considered to occur by availability reduction, favouring plants that can withstand the low-
est water potential. Because light is supplied from above plants, individuals that situate their
leaves above those of neighbours benefit directly from increased photosynthetic rates and indi-
rectly by reducing the growth of those neighbours via shade. In communities where juveniles
recruit in the shade
