Assignment:

Biodiversity is extremely important in maintaining the viability of an ecosystem. When a variety of organisms are present to fill a particular role, ecosystems are more sustainable.

Instructions

Consider the following scenarios involving a pond ecosystem and the introduction of an invasive species of beetle that likes to eat the tall grasses that grow around the edges of ponds.

Scenario A

The invasive species of beetle is introduced into a pond ecosystem that contains a single species of grass. Within months of its introduction, the invasive beetle has consumed all the grasses around the pond, leaving the shoreline bare and exposed.

Scenario B

The invasive species of beetle is introduced into a pond ecosystem with five species of grass; however, the beetle consumes only two species of grasses. A few months later, the beetle has consumed the majority of the two preferred species, but the other three species of grass remain.

Analysis Question

1. Explain how the biodiversity in Scenario B helped create sustainable ecosystem.
2. Research and describe an example of how biodiversity can help maintain a viable ecosystem for one of the following situations: resilience to stress OR resistance to disease.
3. Research and describe an example of how biodiversity can have a negative effect on the sustainability of an ecosystem.

The Importance of Data

Scientists use data to support their positions or arguments. When preparing your responses in this assignment, consider using data obtained from research to create stronger argument.

In the scenarios involving the beetles, data could be used to quantify the shoreline coverage. For example, stating that shoreline coverage in Scenario A decreased 75% compared to 15% in Scenario B would provide more details and create stronger argument.
