SCIENTIFIC INQUIRY
INTERPRET THE DATA The nitrogen-fixing bacterium Rhizobium infects the roots of some plant species, forming a mutualism in which the bacterium provides nitrogen and the plant provides carbohydrates. Scientists measured the 12-week growth of one such plant species (Acacia irrorata) when infected by six different Rhizobium strains. (a) Graph the data. (b) Interpret your graph.
| Rhizobium strain | 1 | 2 | 3 | 4 | 5 | 6 |
| Plant mass (g) | 0.91 | 0.06 | 1.56 | 1.72 | 0.14 | 1.03 |
| Data from J. J. Burdon et al~ Variation In the effectiveness of symbiotic associations between native rhizobia and temperate Australian Acacia: Within-species interactions, Journal of Applied Ecology 36:398-408 (1999). | ||||||
| Note: Without Rhizobium, after 12 Weeks, Acacia plants have a mass of about 0.1 g. | ||||||

For both fertilizers, plant growth began to decrease when 1.5 kg of
fertilizer was given.
D)
Rhizobia are bacteria that live on the roots of some plants, such as legumes like pea plants. Rhizobia convert an element in the
atmosphere into ammonia. Identify and explain the type of relationship this represents.
A)
It is parasitism because the bacteria absorbs food from the pea plant.
It is commensalism because the bacteria and pea plant don't harm each
B)
other.
It is competition because the rhizobia and pea plant both need the limited
amount of available nitrogen.
C)
It is mutualism because the bacteria receives carbon from the pea plant,
D)
Eliminate
while the plant uses the ammopia to make amíno acids.

A group of researchers wanted to determine how leaf herbivory and seed production of a legume plant (legumes are a family of plants which includes beans and lentils) were affected by the presence of its mutualistic rhizobia (a group of nitrogen-fixing bacteria). They designed an experiment with two treatments: (1) rhizobia absent and herbivores present and (2) rhizobia present and herbivores present. Provide two additional treatments and briefly explain how they would contribute to our understanding of the results of this experiment.
The rhizosphere is:Group of answer choices
A.) an area 1-2 mm in thickness adjacent to the root.
B.) Bacteria that assists in the conversion nitrogen gas.
C. ) Fungi that assists in the absorption of micronutrients.
D.) All of the above

There are two-main types of nitrogen-fixing bacteria: free-living (nonsymbiotic) and mutualistic (symbiotic). Describe the mutualistic relationship between Rhizobium and legumes. What is the advantage of using legumes as a cover crop in agricultural systems? A point of interest is that the nitrogenase enzyme complex is highly sensitive to oxygen. This is a major problem for free-living aerobic species such as cyanobacteria and species of the genera Azotobacter and Beiigrinckia. Describe two ways the bacteria can overcome to levels of oxygen in their cells.arrow_forward
