Question

drag each scenario to the correct location on the table. a population of 400 mexican free - tailed bats roost inside a cave and forage for food at night. they primarily prey on insects, like moths. the bats predators include hawks, owls, and snakes. a female bat typically gives birth to one offspring per year. determine whether the scenarios will most likely increase or decrease the population size of the mexican free - tailed bats. increases population size decreases population size some bats are infected with a fatal fungal disease. populations of owls in the area increase. bats from a nearby colony immigrate into the population. improved food quality allows female bats to have two breeding cycles per year. populations of insects in the area decrease.

Explanation:

• Increases Population Size:
• Bats from a nearby colony immigrating adds individuals to the population. Improved food quality allowing female bats to have two breeding cycles per year increases the birth - rate, thus increasing population size. Populations of owls in the area increasing may not directly increase bat population but if it is part of a larger ecosystem balance where it preys on other predators of bats, it could indirectly help.
• Decreases Population Size:
• Some bats being infected with a fatal fungal disease reduces the number of individuals. Populations of insects in the area decreasing means less food for bats, which can lead to a decrease in population due to starvation or emigration.

Answer:

• Increases Population Size: Bats from a nearby colony immigrate into the population., Improved food quality allows female bats to have two breeding cycles per year.
• Decreases Population Size: Some bats are infected with a fatal fungal disease., Populations of insects in the area decrease.
