Play an AI-generated podcast conversation about this lesson

What is the primary factor that determines an organism's success according to the Law of Tolerance?

The range of physical variables it can tolerate (correct)
The complexity of the organism's habitat
The intensity of stress it can respond to
The density of its population

What happens to the tolerance limits for other factors when an organism is not in optimal conditions for one factor?

They remain the same
They increase
They are reduced (correct)
They are eliminated

What is the relationship between ontogenetic age and pressure tolerance in the Lithodes maja?

As ontogenetic age increases, pressure tolerance decreases (correct)
As ontogenetic age increases, pressure tolerance remains the same
Pressure tolerance is not affected by ontogenetic age
As ontogenetic age increases, pressure tolerance also increases
