Summary Introduction
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.

- 4) The figure below displays the three levels of biodiversity. Please label them and the answer the questions below. a) How are these related to one another? What would happen if one or more then one was throw off? b) What are ecosystem services and why are they important to humans? What is an example of an ecosystem service?arrow_forwardA recent study was carried out by a group of environmentalists to analyze biodiversity levels across different habitats, with data shown in the table below. Based on the information in the table, which of the following statements best describes habitat 3?* Genetic Diversity Species Diversity Habitat Diversity Habitat 1 LOW LOW Medium Habitat 2 Medium High Medium Habitat 3 High Low LOW Habitat 4 Medium Low High O Habitat 3 has likely experienced a bottleneck, as indicated by its low habitat diversity. Habitat 3 likely has faster rates of evolution, as indicated by the high levels of genetic diversity. Habitat 3 likely has species with small populations, as ihdicated by its low species diversity. Habitat 3 likely has species with large habitat ranges, as indicated by its low habitat diversity.arrow_forwardImagine 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_forward

- Threats on biodiversity are synergistic. This meansarrow_forwardA(n) community is a group of species that occupy the same area. When studying the diversity of a group of species, ecologists use two measures: One is a count of the total number of species in the area, which is called The other is a measure of how common the species are, compared to each other, which is calledarrow_forward1) Compare the biodiversity indices to one another.

Justify your claim with evidence. Describe the difference in species richness you observed. Explain how human intervention can change biodiversity in positive ways.arrow_forward
