Bees and Fungicides - CER i just need the answers pls ill give you all my points

Certain fungicides are emerging as being harmful to bee health. As of Sept 15, 2015, there are 184 fungicide products registered for use in New York. While foraging, bees can come in contact with fungicides that are sprayed on orchards and in other landscapes. To date, fungicide residues have been detected in pollen, bee bread, wax, and honey in bee hives and nests [1-4]. In fact, next to miticides applied by beekeepers to control varroa, residues in hive materials are predominantly fungicides [5]. Despite the prevalence of fungicide use in conventional agriculture, scientific research is only beginning to uncover how they may affect wild and managed bees. This section provides an overview of what is currently known. For specific details on which fungicides have been researched, as well as other additional information, please consult the articles referenced in this summary. Only a handful of currently used fungicides have been investigated for their impact on bee health, and not all of these have had negative implications.

Laboratory Studies

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
