An experimental forest ecosystem is enclosed in a sealed greenhouse. the entire ecosystem, including the air and soil, is treated with an extremely potent fungicide that kills all fungal life stages including spores. what will probably happen next?
a. plants will enjoy a long-term increase in growth and survival because of the removal of fungal pathogens. b. tree growth will increase because the dead fungi will act as a fertilizer. c. all of the choicesd. a few animals will go extinct due to loss of their fungal food sources, but otherwise the forest will be largely unchanged. e. dead organic matter will accumulate on the forest floor; plant growth will decline because of a lack of nutrients and the loss of mycorrhizal partners.

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
