Instrukcije

This formative assesses understanding of energy flow in ecosystems, ecological relationships, and key characteristics of life. It's designed to reinforce core concepts and highlight connections between living organisms and their environments.

What is a niche?

The role of an organism in its habitat

The population of an organism

The food chain in an ecosystem

The migration patterns of species

A type of symbiosis

A keystone species

1

Which of the following best describes competition?

A relationship where organisms help each other

A relationship between different species only

A random interaction between organisms

1

What is a keystone species?

A species with no impact on its ecosystem

1

What does the Competitive Exclusion Principle state?

All organisms can occupy the same niche

No two organisms can occupy the same niche at the same time

Competition only occurs between different species

Organisms can change their niche at will

1

What type of relationship describes parasitism?

Both species benefit

One species benefits and the other is harmed

One species is unaffected

Both species are harmed

1

Both species benefit

One species benefits and the other is harmed

One species benefits while the other is unaffected

Both species are unaffected

1

What is mutualism?

A relationship where both species are harmed

A relationship where one species is unaffected

A relationship where both species benefit

A relationship that does not exist

What type of reproduction involves one parent?

Sexual reproduction

Asexual reproduction

Genetic reproduction

Cellular reproduction

1

What is homeostasis?

The process of evolution

The regulation of internal conditions

The growth of an organism

The interaction between different species

1

What is a stimulus?

A response to an organism

A condition that requires a reaction

A type of energy

A part of an ecosystem

1

What is adaptation?

A change in an individual organism

A change in a species over time

What role do decomposers play in an ecosystem?

They produce energy from sunlight.

They recycle nutrients by breaking down dead matter.

They act as primary consumers.
