2.4 Ecological Tolerance

• What is ecological tolerance defined as?

  Environmental conditions species survive under
• Ecological tolerance is the range of environmental conditions
• Optimal conditions in ecological tolerance allow a species to thrive with high growth and reproduction.
• What happens to a species in the zone of physiological stress?

  Growth and reproduction impaired
• Match the zone with its effect on the species:

  Optimal ↔️ High growth and reproduction

  Physiological stress ↔️ Impaired growth and reproduction

  Intolerance ↔️ Cannot survive
• Ecological tolerance is crucial for understanding species distributions and responses to environmental changes.
• How many zones are included in the concept of ecological tolerance?

  Three
• Understanding ecological tolerance is crucial for comprehending species distributions and their responses to environmental changes
• What are some factors that influence ecological tolerance?

  Genetic variation, environmental adaptation, species interactions, historical events
• Match the type of ecological tolerance with its environmental factor:

  Temperature Tolerance ↔️ Temperature ranges

  Salinity Tolerance ↔️ Salt concentration

  Light Tolerance ↔️ Light intensity
• Understanding different types of ecological tolerance helps predict species responses to changing conditions.
• How does genetic variation influence ecological tolerance?

  Allows better withstand environmental changes
• Environmental adaptation over generations helps species adjust to new conditions
• Historical events like climate changes can shape a species' ecological tolerance over time.
• What zone do species tend to inhabit based on their ecological tolerance?

  Optimal conditions
• Understanding ecological tolerance is crucial for conservation efforts.
