If a scientist observes a protist that is moving and determines it is heterotrophic, he or she can
then hypothesize that the protist belongs in which group of protists?
A Plant-like
B. Fungus-like
C. Animal-like
D. Virus-like

The correct answer is Option C. Animal-like.

Explanation:

Movement is the characteristics of animals. Animals move from one place to another in search of food. All the animals are heterotrophic in nature which means are unable to make their own food like plants. Animals depends on other organisms for obtaining nutrients. Some animals feed on plants and some on other animals.

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.
