![Ecologists have found a general trend in which, as body size increases, the density of individuals decreases. The graph below shows the body mass versus the density of different species that live in Serengeti National Park. The lions, cheetahs, and hyenas are predators, and the antelope, zebras, and wildebeest are prey. Note that density is graphed on a log scale. Please answer the following questions:
![Graph Description]
- X-axis: Body Mass (lbs), ranging from 0 to 700.
- Y-axis: Log of Density (number/km²), ranging from 0.01 to 1000.
- Points on the graph:
- Gazelle: around 130 lbs, density just above 1.
- Wildebeest: around 600 lbs, density above 10.
- Cheetah: around 100 lbs, density below 1.
- Hyenas: around 150 lbs, density below 1.
- Lion: around 400 lbs, density below 1.
- Zebra: around 500 lbs, density near 10.
Does the relationship between body mass and density follow the general trend described by ecologists? [Select]
Why might some of the species not fit the general trend? [Select]
The predator species all have densities under 1 individual per km², while the prey species have densities above 1. What hypothesis might explain this phenomena?
Living in large groups reduces the probability of any individual being eaten; Predators living in smaller groups reduces competition and can increase cooperation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2d2a894b-5d23-4d74-addb-138aa024bb4a%2F3223d81a-5c36-4916-8a52-8a2b09e710cf%2Fp1eth6a_processed.png&w=3840&q=75)

![**Why might some of the species not fit the general trend?**
- [ Select ]
- Predators and prey have different densities.
- These data from 7 species show that the hypothesized inverse relationship between population density and body mass we went over in class is wrong.
- Four of the species fit, but Gazelles, and maybe Hyenas, are just outliers.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2d2a894b-5d23-4d74-addb-138aa024bb4a%2F3223d81a-5c36-4916-8a52-8a2b09e710cf%2F6wvnw9_processed.png&w=3840&q=75)
