Introduction:
The variety of all plants and animals living together in ecosystem is called biodiversity. It is of three types: genetic, species and ecosystem, all the living organism are distributed according to their habitat.

- Imagine a community of organisms in a forest is affected by a chemical spill that leads to a fire. The fire is contained and burns out and the chemical spill is cleaned up. Monitoring of the plant community following this disturbance researchers noticed that after the spill and fire there was a sharp drop in species diversity, abundance, and richness. Over the next 5 years the area was monitored. The community's diversity, abundance, and richness all increased slightly during the first year however after the first year only the abundance went up during the following 4 years with no changes in any other area. Which of the following models explains these patterns? Restructured Gradual recovery Hangover effect Eliminatedarrow_forwardWhich aspect(s) of biodiversity is/are impacted by each example?
