The Importance of Biodiversity in Ecosystems

The video discusses biodiversity, highlighting its importance in ecosystems by reducing reliance on single species. It contrasts low and high biodiversity, explaining how diverse ecosystems are more resilient to changes. The role of predators in maintaining balance is examined, showing how their removal can disrupt ecosystems. The video concludes with the impact of human activities on biodiversity and the need for conservation efforts.

What is one key benefit of having high biodiversity in an ecosystem?

• Higher chances of species extinction

• Reduced number of species interactions

• Greater resistance to environmental stresses

• Increased reliance on a single species

How does low biodiversity affect species interactions?

• Species become more independent

• Predators have no impact on prey populations

• There is an abundance of food sources

• Species rely more on each other for survival

In a high biodiversity ecosystem, what happens if a food source like shrews decreases?

• Foxes will have no food and die out

• Foxes will find alternative food sources

• The ecosystem will collapse

• All species will migrate to a new area

What is a potential consequence of removing predators from an ecosystem?

• Increase in plant biodiversity

• Decrease in prey populations

• Overpopulation of prey species

• Unchanged biodiversity levels

What is a major threat to biodiversity according to scientists?

• Predator-prey relationships

• Natural disasters

• Climate stability

• Human activities
