The diagrams below show very simplified species relationships for certain areas of African savanna Recall what the direction of arrows means for each type of diagram. Then use these simplified diagrams to answer the next 3 questions. (Note: Real-world savannas support more species with more complex relationships.) Savanna Food Web Lions Cheetahs Elephants Zebra Gazelle Trees Shrubs Grasses Competition Among Savannah Plants Trees Shrubs GrassesExplanation / Answer
1) If a plot of Savannah is fenced so that animals are completely excluded over time, the type of plant species that would dominate according to the diagram was trees. Because trees lie above grasses and shrubs in the plot.
2) If lions are removed, there will be an increase in the population of zebras. Since Zebras are preyed upon by lions, absence of lions will cause increase in zebra population.
3) If cheetahs are removed, there will be an increase in the population of gazelle population. Increase in gazelle population will decrease the population of grasses.
