Low and High Biodiversity

Threats to biodiversity differ from one ecosystem to another. In the forest ecosystem, the primary causes of forest loss are commercial exploitation and population growth (including lifestyle and consumption patterns) and the introduction of invasive alien species.

Guide Questions

  1. What would be the economic advantage of a region with high biodiversity compared to other region with low biodiversity?

There would be more researches that can be done because there are more areas of concern when there is high biodiversity.

  • How does an increase in biodiversity influence balance in an ecosystem?

Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.

  • How does high biodiversity help in maintaining the stability of an ecosystem?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

  • Why is high biodiversity advantageous over low biodiversity in maintaining the stability of an ecosystem?

The high biodiversity of the plant species will aid in the growth and abundance of the animal species which will feed on the plant species thus maintain stability between plant and animal species. The high biodiversity means great source of medicine, food, herbs and meat for the benefit of the human society.

  1. Reflection:

Think of the biodiversity in your community at present. What would it look like in the future?

Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
