Hello. The graph to which this question refers, shows that after a volcanic eruption there is a decrease in the number of species of plants and animals in the region, in between this number begins to grow as time progresses.
Answer:
According to the data, the species richness in an ecosystem is lower one year after the volcanic eruption.
Explanation:
The volcanic eruption has the capacity to decimate many species of plants, as well as species of animals, which decreases the richness of species in this ecosystem. However, the year following the volcanic eruption presents an even smaller species risk, since many species are unable to readapt to the new environment, thus undergoing a process of natural selection. As this adaptation progresses, the number of species will grow periodically, making the species richness greater in the ecosystem in four years.
