• Liquids have a definite shape and volume, while gases have a definite shape.

How does temperature affect the state of matter?

• Temperature changes the color of matter but not its state.

• Temperature influences the state of matter by changing the energy and movement of particles, leading to phase transitions.

• Temperature has no effect on the state of matter.

• Temperature only affects gases, not solids or liquids.

What is the definition of an ecosystem?

• A single organism living in isolation.

• A group of animals in a zoo.

• An aquarium ecosystem.

What is the importance of biodiversity in an ecosystem?

• Biodiversity is irrelevant to ecosystem functions.

• Biodiversity is crucial for ecosystem health, stability, and resilience.

• Biodiversity reduces competition among species.

How do human activities impact the environment?

• Human activities negatively impact the environment by causing pollution, climate change, and habitat destruction.

• Human activities improve the environment by reducing waste.

• Human activities solely benefit wildlife and ecosystems.

• Human activities have no effect on the environment.
