Question

humans process some foods by adding chemicals to reduce harmful bacterial growth. this allows foods to be edible for longer periods of time. which best describes the advantages of food processing? control of density - independent limiting factors such as disease spread control of density - dependent limiting factors such as disease spread control of density - dependent limiting factors such as predation control of density - independent limiting factors such as predation

Explanation:

Disease spread by bacteria in food is a density - dependent factor as it is related to the number of bacteria. By adding chemicals to reduce harmful bacterial growth in food processing, we control a density - dependent limiting factor. Predation is not relevant here as it involves one organism eating another, and the focus is on bacteria in food. Density - independent factors are not related to population density like weather events, not bacterial growth in food.

Answer:

control of density - dependent limiting factors such as disease spread
