What is a limiting factor for competition in animals?
(a)
What is the definition of tolerance in biology?
The ability of any organism to reproduce in any environment.
The ability of any organism to survive when exposed to biotic or abiotic factors.
The ability of any organism to migrate to different habitats.
The ability of any organism to adapt to only biotic factors.
What does the range of tolerance refer to?
The specific temperature range an organism can live in.
The upper and lower limits that define the conditions in which an organism can survive.
The range of food sources an organism can consume.
The range of habitats an organism can occupy.
What is the optimum temperature zone for steelhead trout?
The temperature range where the greatest number of steelhead trout live
The temperature range where no steelhead trout live
The temperature range where steelhead trout cannot survive
The temperature range where steelhead trout are least active
What might happen to steelhead trout if temperature limits are stressed?
They will thrive and increase in number
They may not survive
They will become more active
They will migrate to colder regions
What is the term used to describe the absence of steelhead trout beyond their tolerance limits?
(a)
What is the significance of the water temperature being outside the range of tolerance for steelhead trout?
It is beneficial for their growth
It is a limiting factor
It has no effect
It increases their population
