A primatologist tracks fruit consumption by a group of 25 chimpanzees. Each chimpanzee eats 1.2 kg of fruit daily. After 10 days, 5 more join the group, and consumption per individual rises to 1.5 kg/day due to increased activity. What is the total fruit consumed over 25 days? - Dyverse
Total Fruit Consumption by a Group of Chimpanzees Over 25 Days: A Detailed Breakdown
Total Fruit Consumption by a Group of Chimpanzees Over 25 Days: A Detailed Breakdown
Tracking primate diets offers fascinating insights into chimpanzee behavior and ecological interactions. A recent primatological study tracked the daily fruit consumption of a chimpanzee group, revealing how social dynamics and group size affect nutritional needs. Here’s a comprehensive breakdown of the total fruit consumed over a 25-day observation period.
Initial Group and Daily Consumption
The study began with 25 chimpanzees, each consuming an average of 1.2 kg of fruit per day. Over the first 10 days, total daily consumption was:
25 chimpanzees × 1.2 kg/day = 30 kg/day
Understanding the Context
Over 10 days, this amounted to:
30 kg/day × 10 days = 300 kg
Expansion of the Group and Increased Intake
After day 10, 5 additional chimpanzees joined the group, increasing the total to 30 chimpanzees. Due to heightened activity and social engagement, each individual’s intake rose from 1.2 kg to 1.5 kg/day.
For the remaining 15 days, daily consumption became:
30 chimpanzees × 1.5 kg/day = 45 kg/day
Total consumption over these 15 days was:
45 kg/day × 15 days = 675 kg
Key Insights
Total Fruit Consumption Over 25 Days
Adding both phases of observation, the complete fruit consumption is:
300 kg (first 10 days) + 675 kg (next 15 days) = 975 kg
Conclusion
This study highlights how primate groups adapt their diet based on size and energy demands. Over the full 25-day period, the chimpanzee community consumed a total of 975 kilograms of fruit—a testament to their dynamic ecological role and social behavior.
Understanding these patterns helps conservationists and researchers better protect wild chimpanzee habitats and inform primate care in sanctuaries worldwide.
