Part C - Preserving biodiversity
In the past, preservation efforts usually focused on single species, such as polar bears or Florida panthers. However, current preservation efforts generally focus on whole communities and ecosystems. One approach to the preservation of biodiversity on this scale is the establishment of protected areas such as natural parks and reserves.
Marine reserves are protected areas in the ocean where harvesting fish and invertebrates is limited or prohibited. Generally, these reserves protect a coral reef ecosystem, a kelp forest ecosystem, or an area near a particular shoreline, rather than a single species. The following graphs represent changes typical after the establishment of some well-planned marine reserves. Interpret the graphs and determine which of the following statements are true
