Microorganisms can mutate and evolve very quickly compared to most multicellular organisms. this allows pathogenic microorganisms to infect new species. suppose a very harmful microorganism that is quite successful at infecting hardwood trees is introduced into a forest ecosystem.

what effect would this pathogenic microorganism most likely have?

a> it would disrupt the ecosystem by greatly reducing the population of a few species.

b> it would maintain the balance of the ecosystem by reducing the population of one species.

c> it would disrupt the ecosystem by infecting and killing the populations of all the species.

d> it would maintain the balance of the ecosystem by reducing the populations of all the species.

Atree root breaking a rock into smaller fragments is an example of both and mechanical weathering. when rocks are exposed to heat, they which can contribute to thermal stress. when harmful gases, such as sulfur dioxide and nitrogen oxide, react with water in the atmosphere, they can produce the agent of erosion involved in stream erosion is when the ground is so saturated that it can't absorb rainfall or when rain falls so quickly that the ground can't absorb the water, forms. a/an is a huge, heavy, moving body of ice that picks up rocks and sand and erodes the ground beneath it as these materials scrape across it. hot arid climates are prone to erosion by rows of trees and shrubs planted to protect fields from wind erosion are known as
