Figure 4-8 shows how the populations of two different species changed over time. what is the relationship between these two species? how did the sudden change in the population of one species between 1900 and 1920 affect the population of the other?

As the carnivores decreased in population, the herbivores increased in population.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
