it is discovered that the algae-killing product (AlgaeBdead) that spilled in Lake Ontario also inhibits (slows) the growth of fungi in the lake. Explain one way this would negatively affect the lake ecosystem.
The black spot fungus is known to attack roses in humid climates. Initially, small black spots appear on the leaves. The entire plant can die if not treated. From this information, what is mostly the main cause of the demise?
Fairy rings (such as the one in the photo on the left) are circles of fungi that often appear in open meadows and in forest areas. In the soil beneath the fungi is an ever-extending mycelium. As the mycelium spreads to seek out more food, it sometimes will produce the fungi we see above ground to produce and release spores. The diagram on the right depicts the outline of a fairy ring that has appeared overnight in an open meadow, as viewed from above. The ring represents the farthest advance of this mycelium through the soil. The letters A-D represent locations with respect to that ring which are all 0.5 meters below the soil surface.
1)If the fungus that produced the fairy ring can also produce arbuscules, then which of the following is most likely to be buried at location "B"?
a. cement-capped well
b. deceased animal
c. tree stump
d. fire pit
2) Assume that all four locations are 0.5 meters above the surface, rather than below. On a breezy day with prevailing winds blowing from right…

- Fairy rings (such as the one in the photo on the left) are circles of fungi that often appear in open meadows and in forest areas. In the soil beneath the fungi is an ever-extending mycelium. As the mycelium spreads to seek out more food, it sometimes will produce the fungi we see above ground to produce and release spores. The diagram on the right depicts the outline of a fairy ring that has appeared overnight in an open meadow, as viewed from above. The ring represents the farthest advance of this mycelium through the soil. The letters A-D represent locations with respect to that ring which are all 0.5 meters below the soil surface. Which location (A-D) is nearest to the basidiocarps? ___ What is the most probable location (A-D) of the youngest portion of this mycelium? ___arrow_forwardAn apple farmer notices that some of the trees in his orchard have a fungus on them and those trees have necrotic ring spots typically associated with a viral infection. The trees that don't have fungus appear to be healthy. What is the most likely conclusion the farmer can make here?arrow_forwardThe fungus Botrytis cinerea is a pathogen of plants, and causes high losses of strawberry crops around the world. In Europe, most B. cinerea fungi are killed by fungicides (chemicals sprayed on the crops to kill the fungus). However, some B. cinerea are resistant, and continue to live even when exposed to fungicides. If the currently-used fungicides continue to be sprayed on strawberry crops in Europe, what is expected to happen? (Choose one.) a)The strawberries will eventually become larger and more resistant to fungicides. b)The strawberries will form a beneficial association (mutualism) with the B. cinerea, and both will be resistant to the fungicides. c)Strawberry plants will preferentially be colonized by B. cinerea that are not resistant to fungicides. d) The proportion of B. cinerea that are resistant to fungicides will increase in the population over time, and these fungicides will no longer be effective at killing most of these fungi.arrow_forward

Several different fungi have been implicated in (thought to be the cause of) decreases in frog numbers. In particular, shrub frogs are especially at risk. You test several different fungi species to see how they affect sample populations of splotched frogs, a close relative of the shrub frog that is not endangered. To do this, you use the different species of fungi to infect populations of splotched frogs and then measure survival rates of these frogs at different frog densities. Frog densities are given in column 1 of the table below. The frog population in column 2 is the control, which was not infected with a fungus. Initial density of frog population (before introduction of Frog survival Frog survival Frog survival Frog survival Frog survival rate rate rate rate rate Control Fungus Fungus Fungus B. grenchius Fungus B. sporifera B. noeltid B. talbuta fungus) Per 1000 m2 10 0.95 0.72 0.83 0.90 0.5 50 0.9 0.64 0.82 0.87 0.35 75 0.88 0.66…arrow_forwardWhy would it be disadvantageous for a plant to form a symbiotic relationship with a mycorrhizal fungus when phosphate is abundant in the soil surrounding its roots?arrow_forward
- ATS Canvas Support Identify whether each of the statements is an Observation or a Hypothesis to explain an observation. Golden toads laid their eggs in shallow pools of water between the roots of cloud forest trees. Golden toad tadpoles lived in shallow pools of water on the cloud forest floor before developing into toadlets. Over warm ocean water, clouds form higher in the atmosphere. Golden toads had highly specialized reproductive habitat. Golden toads were found only in the cloud forest of Monteverde, Costa Rica. The fossil record and current trends show that highly specialized species with small populations and narrow ranges are highly susceptible to extinction. Spring 1987 was the driest spring on record for Monteverde. All the golden toad tadpoles might have died during the spring of 1987 because their pools dried up before the young could lead a fully terrestrial life. The drier conditions at Monteverde in 1987 might have been caused by clouds forming higher in the atmosphere,…arrow_forwardOn the first official “Arbor Day”, people in the state of Nebraska planned more than ————- trees.arrow_forwardThe microorganisms responsible for symbiotically fixing nitrogen in the nodules on the roots of legume plants are: bacteria actinomycetes algae fungi O autotrophsarrow_forward
- Assume you have an invasive fungus species growing in your backyard and you want to get rid of it.

Why do you think that happened?arrow_forwardBiologists have discovered that many mycorrhizal fungi are sensitive to a low pH.
