A more recent threat to tree survival is a fungus in the genus Phytophthora which can kill full-grown trees. Studies indicate that the fungus can arrive via footwear of hikers.
What is a possible solution to reduce fungus arrival or prevent the fungus on footwear from reaching the trees?
If all of the saprophytic fungi in an ecosystem died, which of the following would be a likely short-term result?
Group of answer choices
Plants would not be able to absorb nutrients from the soil as effectively
Dead plant material would be decomposed more quickly, releasing higher levels of CO2
Less carbon dioxide would be released into the atmosphere because dead plant material would not be decomposed
Plants would be unable to absorb nitrogen as efficiently because their root symbiotic fungi would be unable to break gaseous nitrogen apart Plants would be unable to absorb nitrogen as efficiently because their root symbiotic fungi would be unable to break gaseous nitrogen apart
Which of the following plant pathogens have had a large impact on civilization over the years?
Claviceps purpurea
Saccharomyces
Phytophthora infestans
All of the above

The beetles carry the fungus to the fig trees, which kills the fig trees. The fig trees require the fungus to survive, but the beetles eat and kill the trees. The beetles require both the fungus and the fig trees to survive. The fig trees infect the beetles with the fungus, which kills the beetles.arrow_forward

- In the early 1800s, potatoes became the main food staple for the people of Ireland. In 1845, a fungus native to South America, Phytophthora infestans, began to infect potato plants, causing potato blight and making the tubers inedible. Over the next several years, most of the potato plants in the country were destroyed by this invasive species. Which of the following statements correctly explains why the Irish potato famine occurred? The arrival of ships from South America led to human introduction of the disease. A drought across Ireland in 1844 led to more damaged potato plants that were susceptible to infection. An increase in trade with other European countries led to the introduction of plants that were already infected with the fungus. Ireland's climate became closer to that of South America, which allowed the fungus to infect potato plants and reproduce.arrow_forwardWhat steps would it take for a fungus to establish a symbiotic relationship with plants? I understand that there are symbiotic soil fungi that are entangled amongst plant roots but this question I am wondering how they form a relationship if the fungus live between the plant cells.arrow_forwardYou’ve been noticing that a local pond has developed a green scum that is getting thicker and thicker.
