Analysis:
According to the data as habitat sizes increase, biodiversity and species richness increases. The smaller the habitat size, the less species diversity and richness. From the data, there are fewer species that could fit in the smaller habitats, such as in the 1 by 1 m boxes. With fewer species in the boxes, this results in less diversity. The larger habitat sizes could fit more species meaning that they had a greater amount of species richness, resulting in larger diversity. At the beginning of the graphs, the data started out low, then as habitat size increases along the x-axis, species richness and biodiversity increases. However, in biodiversity, the data did not increase like species richness; the data does up and down as it also increases as habitat size increases.
Conclusion:
This experiment characterizes the richness and diversity of individual species. It demonstrates how the smaller the habitat sizes, the decrease in species richness, which leads to a decrease in biodiversity. The more space in a habitat, the more species and biodiversity. This trend is due to the amount of resources or niches that are available for the species. The habitat size determines how much resources or niches that are available in that given area. Without the needed resources and niches, the certain species may die off or relocate to a different area, resulting in a decrease in species richness and biodiversity in a given area. Habitat loss decrease habitat sizes for species and are frequently caused by humans through deforestation, habitat destruction, harvesting fossil fuels, urbanization, and logging.
Discussion:
Habitat destruction is the process in which natural habitat is provided unable to support the species present. Species that were previously in a given area are displaced or destroyed, reducing biodiversity. The main cause of habitat loss is because of human activity. Humans cause habitat loss by using up land resources and creating waste for their own benefit. The main causes for habitat destruction are agricultural industry, hu...
