Ecosystem A is located in a jungle with numerous types of plants and animals while Ecosystem B has very few plants and only a small number of tiny lizards and mammals, mostly mice. Which ecosystem is more stable and resistant to changes? And why?
Ecosystem A is more stable due to its high biodiversity. It would be able to recover easier from a disturbance like a fire, flood, storm, or drought.

Graph should show prey pop going up and predator going down. then predator inc and prey dropping.
Organsisms like the wolves of yellowstone, otters of the pacific coast, or elephants of the savannah have a large impact on their ecosystems and if they were removed the ecosystem would be badly damaged and potentially collapse. What do we call these important types of organsims?
