Equilibrium Concepts in Ecosystems

The video tutorial explores the concept of equilibrium, focusing on stable, unstable, and neutral types. It provides practical examples using everyday objects to illustrate these concepts. The video also discusses dynamic stable equilibrium, using examples like home heating systems and ecosystems. The tutorial aims to clarify how different types of equilibrium function and their significance in science and daily life.

What is the general definition of equilibrium?

• A state of chaos

• A state of balance

• A state of rest

• A state of constant motion

What happens to a ball in unstable equilibrium when disturbed?

• It disappears

• It returns to its original position

• It moves further away from its original position

• It stays in the new position

In stable equilibrium, what occurs when a ball is moved from its equilibrium position?

• It stops moving

• It returns to the equilibrium position

• It moves further away

• It stays in the new position

What is neutral equilibrium?

• A state where an object stays in a new position

• A state where an object moves further away

• A state where an object disappears

• A state where an object returns to its original position

How does a dynamic stable equilibrium differ from a static one?

• It is always neutral

• It is always unstable

• It remains unchanged

• It involves constant change

What role does a thermostat play in a dynamic stable equilibrium?

• It decreases the temperature continuously

• It increases the temperature continuously

• It triggers heating or cooling to maintain balance

• It keeps the temperature constant

In an ecosystem, what happens when the prey population increases?

• The predator population decreases

• The prey population becomes extinct

• The ecosystem collapses

• The predator population increases

What is the effect of adding pencils and clay to the styrofoam sphere and soda bottle system?

• It makes the system stable

• It makes the system neutral

• It has no effect

• It makes the system unstable

Why do tightrope walkers use long poles?

• To look impressive

• To lower the center of gravity

• To make the walk more challenging

• To increase their height

What is the main characteristic of dynamic stable equilibrium in ecosystems?

• Fluctuating population levels

• Constant population levels

• No predators

• No prey
