Amolecule of chlorine has atoms of the same element, and a molecule of carbon dioxide has different kinds of atoms, chlorine is a. change of state b compound c an element a d mixture and carbon dioxide is a. change of state b compound c element d mixture .

Answer;

Chlorine is an element while carbon (iv) oxide is a compound.

Explanation;

-An element is a pure substances that is made up of similar types of atoms. Elements unlike compounds can not be divided into simpler forms using chemical means. Examples of elements include; potassium, chlorine, helium, sodium, etc.

-Compounds on other hand are substances that contain more than one atom from different element that are combined together chemically. The atoms in a compound are in a fixed ratio. Compounds can be divided into simpler forms using chemical means. Example of compounds include; carbon (iv) oxide, water, etc.

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.
