The symbiotic relationship between plant roots and mycorrhizae fungi is an example of mutualism true or false

True.

Explanation:

Mycorrhizae play important roles in plant nutrition, soil biology and soil chemistry. These are fungi that colonize plant roots and extend far into the soil. The association with most plants is generally mutualistic, but in certain cases with certain species, mycorrhizae may be very parasitic in the host plants.

“Myco” – “rhiza” literally means “fungus” – “root” in Latin

Approximately 95% of plant species on the planet form a symbiotic relationship with the beneficial mycorrhizae fungi.

The plant makes organic molecules such as sugars by photosynthesis and supplies them to the fungus, and the fungus supplies to the plant water and mineral nutrients, such as phosphorus, taken from the soil.

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.  

the titanic would be the correct answer
