To survive and coexist together while competing for the same nectar of a fl ower in a garden, the two butterfly species
may avoid competition through resource partitioning, specifically by choosing different foraging patterns.
Resource partitioning refers to the division of limited resources among competing species to reduce direct competition.
It is a valuable mechanism that allows competing species to share resources and thrive in the same ecosystem. In the given case, the two butterfly species may exhibit resource partitioning by selecting different foraging patterns. For example, they may choose different parts of the fl ower, such as one species primarily feeding on the upper petals while the other focuses on the lower petals. They might also prefer different fl ower species or forage at different times of the day, effectively utilizing the available nectar without directly interfering with each other’s feeding activities. By adopting these different foraging strategies, the butterflices can coexist in the same garden, reducing the intensity of competition for nectar resources.
You may recall the resource partitioning mechanism observed by Mac Arthur in different warbler species to avoid
Competition and coexist on the same tree. 
(1) If both butterfly species feed at the same time on the same nectar resources, it would increase the intensity
Of competition between them and may lead to exclusion of competitively inferior species.
(3) Increasing the time spent on attacking each other would escalate the competition between the two butterfly
Species rather than promoting coexistence. Aggressive interactions and competition for resources can lead to the exclusion of one species by the dominant species, and it does not facilitate coexistence.
(4) If one butterfly species preys on the other, it would lead to a predator-prey relationship rather than coexistence
Through resource partitioning. Predation is a form of direct interaction that typically reduces the abundance of prey species, and it does not promote coexistence in this context.
