Epidemiology studies health-related states and occurrences (not simply diseases) in specific communities.Therefore, option (A) is correct.
What is epidemiology?The study and analysis of the distribution, patterns, and determinants of health and disease conditions in a given population is what epidemiology is all about. It is one of the most important aspects of public health, and it influences both policy decisions and evidence-based treatment by determining the factors that put people at risk for disease and setting goals for preventative medical care.
Descriptive, analytical, and experimental methods are the three primary approaches utilized in epidemiology. Descriptive epidemiology is the method that is utilized the most to investigate the occurrence of disease, despite the fact that all three can be employed to do so.
Therefore, option (A) is correct.

Help please and are the ones that already answered to are correct ?
Yes, all of your answers are correct except for number 12. Instead I would say a food chain outlines who eats whom but a food web is all of the food chains in an ecosystem.
Primary consumers are basically herbivores, such as squirrels, rabbits, crickets, etc.
Secondary consumers are carnivores/omnivores, animals that eat other animals such as foxes, snakes, and owls.
Higher order consumers are animals that can eat more things, like humans for example, because we eat animals that are bigger than us like cows but we also eat plants.
Omnivores are animals that eat meat and plants, such as humans and mice because according to your food web, mice also eat meat.
I can’t see the picture very well because it’s blurry, but i think the owl eats some kind of animal that looks like a frog and snakes, so if the owl is removed the frog animal thing and snakes would increase.
for the last question, i would say
