Ecosystem Sustainability and Biodiversity

The video tutorial by Micheel explores how biodiversity contributes to the sustainability of ecosystems. It explains the importance of having a variety of species and ecosystems to withstand natural disasters, diseases, and human activities. The tutorial also covers the concept of sustainability, emphasizing the ability to survive and maintain into the future. Through examples, it illustrates how biodiversity affects food webs and the survival of species. The video concludes by discussing threats to ecosystem sustainability, such as limited resources, environmental changes, and human activities.

What does biodiversity refer to in an ecosystem?

• The total number of organisms

• The variety of species

• The size of the ecosystem

• The amount of available food

How does genetic diversity within a species contribute to its survival?

• It prevents natural disasters

• It reduces the need for food

• It allows for better adaptation to environmental changes

• It increases the population size

What is the primary meaning of sustainability in an ecological context?

• The ability to consume more resources

• The ability to remain unchanged

• The ability to grow rapidly

• The ability to survive and maintain into the future

Why would a koala population be at risk if eucalyptus trees were wiped out?

• Koalas can eat other types of leaves

• Koalas rely solely on eucalyptus leaves for food

• Koalas can survive without food for long periods

• Koalas can migrate to other areas

What would happen to a frog if its only food source, ants, were eliminated?

• The frog would find another food source

• The frog would die due to lack of food

• The frog would adapt to eat plants

• The frog would migrate to a new area

Which food web is more sustainable?

• One with fewer links

• One with more links

• One with only animal-based links

• One with only plant-based links

What is a major threat to ecosystem sustainability?

• Stable climate

• Abundant resources

• Invasive species

• Balanced food web

How do plants contribute to the sustainability of an ecosystem?

• By consuming carbon dioxide

• By producing oxygen and food

• By increasing soil erosion

• By reducing biodiversity

What is a limiting factor in an ecosystem?

• A factor that affects population size

• A factor that stabilizes the ecosystem

• A factor that decreases resources

• A factor that increases population

Why is it important to preserve species that we may not fully understand?

• They might be harmful

• They could provide future benefits

• They are always beneficial

• They are not important
