Ecosystem Tolerance and Its Impact on Environmental Stability

The video explores the concept of ecosystem tolerance, explaining how ecosystems function within certain limits and what happens when these limits are exceeded. It introduces the bell curve model to illustrate optimal, stressed, and intolerance zones, highlighting the impact of human activities on ecosystems. The video emphasizes the importance of understanding these concepts to mitigate negative effects and promote ecosystem recovery.

What is the primary focus of the video on ecosystem tolerance?

• The impact of climate change on ecosystems

• The role of predators in ecosystems

• Defining ecosystem tolerance and its environmental significance

• The importance of water cycles in ecosystems

Which of the following is NOT a factor in ecosystem functionality?

• Climate

• Soil type

• Human emotions

• Nutrient cycling

In the bell curve model, what does the center represent?

• The stressed zone

• The intolerance zone

• Optimal conditions

• The abiotic zone

What is the significance of the bell curve in ecosystem tolerance?

• It shows the relationship between predators and prey

• It illustrates the gradient of environmental tolerance

• It depicts the water cycle

• It explains the food chain

Which zone indicates that an ecosystem is functioning correctly?

• Abiotic zone

• Optimal conditions zone

• Intolerance zone

• Stressed zone

What happens to an ecosystem in the stressed zone?

• It experiences a decrease in population size

• It functions optimally

• It remains unchanged

• It becomes more biodiverse

What might help an ecosystem recover from the stressed zone?

• Increased human activity

• Continued environmental stress

• Removal of stress factors

• Introduction of new species

What is a possible cause for an ecosystem to enter the intolerance zone?

• Human activity

• Stable climate conditions

• Optimal nutrient flow

• Increased biodiversity

What is a key characteristic of the intolerance zone?

• High biodiversity

• Stable ecosystem functionality

• Failure to function properly

• Optimal nutrient cycling

What is the role of human activity in ecosystem tolerance?

• It has no impact on ecosystems

• It always improves ecosystem health

• It only affects abiotic components

• It can push ecosystems into the intolerance zone
