Ling feeds her guppies one-half teaspoon of fish food every day. the average guppy population in her aquarium over a four-month period is 38 guppies. she increased the food to one teaspoon per day. after a four-month period, the average population is 53 guppies. which of the following statements is supported by these data?
a. the size of the aquarium was a limiting factor.
b. food was a limiting factor.
c. as long as ling keeps adding more food, the guppy population will continue to grow
d. guppies reproduce rapidly.

B. Food was a limiting factor.

C. As long as Ling keeps adding more food, the guppy population will continue to grow

Explanation:

Limiting factor refers to biotic or abiotic factors that limit or affects the growth of species. In the population of guppies, food was a limiting factor that affects their population growth. Indeed!, it is vivid from the experiment that after Ling increases the amount of food being given to the guppies, there is a significant increase in the population growth.

We can thereby conclude that  the following statements that supported these data goes thus;

Food was a limiting factor and as long as Ling keeps adding more food, the guppy population will continue to grow.

the denominator has a very specific role.
