A plant biologist from Harvard University hypothesized that garlic mustard, an invasive plant found in forests of the northeastern United States, suppresses the growth of trees by harming mycorrhizal fungi in nearby soil. To test this hypothesis, soil samples from invaded and uninvaded woodlands were collected, and half the samples were sterilized to kill fungi. Two species of maple tree seedlings were planted, and the growth was calculated (as a percentage increase in the mass of the plant). Do the data in the graph support the hypothesis that garlic mustard slows tree growth by harming soil fungi? GRAPH CANT COPY
44. In the interaction between damselfish and cleaner fish, if a damselfish has few parasites, the cleaner fish will A) add parasites. B) ignore the damselfish. C) bite and eat parts of the damselfish. D) not change its behavior towards the damselfish. 45. Garlic mustard is a plant that has been introduced to North America. It produces a chemical that kills mycorrhizal fungi in the forest where it grows. How would killing mycorrhizal fungi affect native trees in the forest? A) Tree seeds will not be dispersed. B) Tree flowers will not be pollinated. C) Trees will be more vulnerable to herbivores. D) Tree growth will be reduced.
