5. what are some positive effects of a slow change to an ecosystem?

Species of animals can learn to adapt, preventing a massive decrease in a species' population or extinction.

It's my only one right now. Sorry if I wasn't of much help.

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.

We can plant more trees and plants.
