APES Unit 2.4 Ecological Intolerance

​ (a)   Intolerance refers to the range of conditions that an organism can endure before injury or death results.

• Ecological
• Economic
• Environmental
• Environogical

Match Definition to the correct Range

Groups:

(a) Optimum Range

,

(b) Tolerance Range

,

(c) Zone of Intolerance

• Where organisms survive but experience some stress

• Where organisms survive, grow, and reproduce successfully

• Where the organisms will die

Answer explanation

Tolerance range is also called zone of stress

Organize these conditions into the ecosystem it would most apply in on the Ecological Intolerance Range

Groups:

(a) Terrestrial

,

(b) Aquatic

,

(c) Both

• Salininity

• Precipitation

• pH

• Temperature

• Flow Rate

• Humidity

• Turbidity

• Sunlight

The range of ideal conditions for a species to survive, grow, and reproduce

• Fundamental Niche

• Realized Niche

• Niche Specialists

• Generalists Specialists

Answer explanation

Essentially, the fundamental niche states if the blueprint for the conditions of which a species success is met, they will real optimal survival (think about the middle section of the ecological intolerance range)

Realized Niche

• The range of ideal conditions of a species to survive, grow, and reproduce

• The range of abiotic and biotic conditions under which a species actually lives

• The range where organisms survive but experience some stress

• The range where organisms will die

Answer explanation

Basically the legitimate area an organisms lives in and the conditions rather than where environmentalists say they should be for optimal livelihood.

The____ hypothesis states that ecosystems that experience ____ levels of disturbance are more diverse than those with high or low disturbance levels.

Answer explanation

Basically, an ecosystem can be the most diverse when it reaches the sweet spot of disturbances: not too many but not too little. Some disturbance is good because it keeps species that tend to outcompete others (primarily generalists,) in their place and prevents them from growing in large numbers pushing the competition (primarily specialists) to extinction. Which of course, would decrease biodiversity.

Where is the zone of stress

Answer explanation

It is also called the intolerance range and it's always after the middle section

There is more than one type of Range of Intolerance Diagram. Based on the sectioned off portions on this one, press where the zone of intolerance would be.

Answer explanation

If there are only 3 sections on the curve you can assume it's on the tail end. Idk why but thats what was happening in that guys' video so it's good to know just in case mrs. groome throws it in there or it's on the AP test.

Match em

Groups:

(a) Resistance

,

(b) Resilience

,

(c) Applicable to Both

• A measure of how much a disturbance can affect the flow of energy and matter

• The rate of which an ecosystem returns to its original state after a disturbance

• Categorizes the productivity of a system after a disturbance

Answer explanation

• - Little changed after a disturbance = high resistance

• ex: people who have little no no biological problems after eating lactose high resistance to lactose

-Reverts back quickly after a disturbance = high resilience

ex: people who are lactose intolerant but only can quickly recover and go back to their normal functions are resilient (in the context of the APES definition)

Realized Niche Biotic conditions

• Disease

• Starvation

• Producers

• Predators

Answer explanation

These are some actual conditions organisms are faced with that are non-living (this is in reference to realized niche)
