Apopulation of 400 mexican free tailed bat roostinside a cave and forage for food at night they primarily pray on insects like moths the bats predators include hawk owls and snakes a female that 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 bat

Populations of insects in the area decrease - Decrease

Populations of owls in the area increase - Decrease

Some bats are infected with a fatal fungal disease - Decrease

Bats from a nearby colony immigrate into the population - Increase

Improved food quality allows female bats to have two breeding cycles per year - Increase

Explanation:

A population of bats can be affected by numerous factors as to will its population increase or decrease, just as at any other organism. If the populations of their food source decrease, the bats will have less food, thus their numbers will decrease. The same goes is a deadly diseases spreads among them, as many will be infected and will die out. They also have predators, so if some of their predators has increase in its population, the population of bats will go down. On the other hand, if the amount and quality of food is better, and the females are able to breed twice a year instead of once, than the population will grow. If bats from the same species but from another colony move in and join the population, than the population will have rapid increase.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
