A researcher found that the reproductive success of bumblebees decreased when the population density of honeybees increased. The decline in the number of bumblebees appeared to be a result of competition for nectar.

Explanation:

Topics regarding community ecology will study the interaction between different species that occurs within a certain type of environment.

The interaction could be anything as long as it influence each other's population, distribution, structural position within the evolutionary scale, and the spatial space where both species live in. (the interaction between bumblebees and honeybees above fill this criteria)

the factors that the economies of the muslim empires prosper were:

1- land trade routes-located between three continents  

2- sea trade routes

trade contributed to the spread of muslim empires, and with that islamic culture led to a growing feeling of internationalism resulted in the transfer of technology, science, and other cultural forms.
