![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:

Why might some of the species not fit the general trend?

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)

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
iiving in Smanici groups iuucts competition and can meitast cooperation](/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)
