The figure below shows the relative abundance (y axis) of shrubs in an ecosystem in the years following a fire (x axis). The shrubs in this ecosystem fall into two functional groups: fire recruiters and fire persisters. RELATIVE SHRUB SEEDLING ESTABLISHMENT FIRE-RECRUITER SYNDROME FIRE-PERSISTER SYNDROME Fire 1 10 100 LOG YEARS If fire frequency decreased significantly in this ecosystem, which group would be benefited? Both functional groups would benefit equally Fire recruiter species Fire persister species

However, their abundance tends to decrease over time as other species, including fire persisters, start to dominate. Fire persisters, on the other hand, are species that can survive fires and continue to grow and reproduce afterwards. They may not thrive Show more…

Below are data from a study following different grassland habitats that experience fire at different frequencies. In each graph, the x axis is the number of plant species found in the habitat and the y axis is the percent of grassland habitats sampled. The habitats are split into those experiencing fire approximately every year (left), every 5 years (middle), and every 10 years (right). Do these data support the intermediate disturbance hypothesis? Group of answer choices Yes No We cannot determine if the hypothesis is supported from these data

Researchers are studying lichens growing on trees in a forest ecosystem. At the beginning of the study, the researchers identified twelve lichen species in the forest. Later, a forest fire happened in the study area. The researchers returned to the area and found only six lichen species. Which inference is best supported from the researchers' observations? Forest Fires will permanently remove certain species from the ecosystem: Most lichen species are unaffected by forest fire: The biodiversity in a forest increases after a fire Certain lichen species are better adapted to survive forest fires than others.

Forest Fires and Acres Burned Number of fires and number of acres burned are as follows: $$ \begin{array}{l|llllllll}{\text { Fires } x} & {72} & {69} & {58} & {47} & {84} & {62} & {57} & {45} \\ \hline \text { Acresy } & {62} & {42} & {19} & {26} & {51} & {15} & {30} & {15}\end{array} $$ $$ \text { Find } y^{\prime} \text { when } x=60 \text { fires. } $$
