Primary and secondary succession, climax communities. What type of milk would affect the bacteria you might find? What conditions are best for different bacteria?

Explanation:

Pasteurised milk is a milk which heated at a certain temperature to kill the microorganism or bacteria present in the milk.

The conditions which are best for bacteria to grow:

1. Bacteria needs food to grow.

2. Bacteria requires water for survival.

3. Bacteria needs optimum temperature i.e., 37 C and oxygen.

4. Bacteria at neutral PH i.e., between 6.6 and 7.5 shows best growth.

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.
