The best explanation for a decrease in the number of producers in a food web is 'C-- an increase in the population of primary consumers'.
Explicación
## Step 1The problem is asking us to identify the factor that would best explain a decrease in the number of producers in a food web. Producers, such as plants, are organisms that produce their own food through photosynthesis. They are the base of the food web and provide energy for all other organisms in the ecosystem.## Step 2Let's analyze each option:### Option A: An increase in the amount of energy received from the sun would generally lead to an increase in the number of producers, as they rely on sunlight for photosynthesis. This would not explain a decrease in the number of producers.### Option B: An increase in the amount of atmospheric carbon dioxide could potentially benefit producers, as they use carbon dioxide for photosynthesis. This would not explain a decrease in the number of producers.### Option C: An increase in the population of primary consumers would mean that more producers are being consumed, which would lead to a decrease in the number of producers. This is the most plausible explanation for a decrease in the number of producers.### Option D: A decrease in the number of apex predators would not directly affect the number of producers. Apex predators are at the top of the food chain and do not directly consume producers.
