Birds eat mosquitoes that carry the zika virus. Bats pollinate plants such as bananas, peaches, and agave. Iodine supplements are extracted from marine algae. Roots of vegetation trap and hold soil on the banks of rivers. Fungi, bacteria, and deep-sea organisms produce anticancer and anti-biotic chemicals. Fungi distribute nutrients in tropical rainforests through a network of fibers called hyphae. Ocean algae perform photosynthesis. Wetland plants function as natural sponges that trap and slowly release water. Nitrogen-fixing bacteria and nitrifying bacteria are the only source of nitrogen for wild plants and food crops. Decomposition breaks apart dead bodies. A spider eats about 2,000 insects each year. Kelp, a type of marine algae, is used as a thickening agent to produce ice cream, jelly, salad dressing, and toothpaste.

a time line cause it goes from 685 to 978

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.
