Ecological Concepts and Interactions

The video tutorial explains the difference between habitat and niche, using examples to illustrate these concepts. It discusses biotic and abiotic factors that influence ecosystems and introduces the competitive exclusion principle, which states that two species cannot occupy the same niche in the same habitat simultaneously. The video concludes by summarizing the key points discussed.

What is the primary difference between a habitat and a niche?

• A habitat is where an organism lives, while a niche is its role in the ecosystem.

• A niche is where an organism lives, while a habitat is its role in the ecosystem.

• A niche is a type of habitat.

• A habitat and a niche are the same thing.

Which of the following is an example of a habitat?

• Rainforest

• Herbivore

• Predator

• Carnivore

Which of the following best describes a niche?

• The climate conditions of an area.

• The food an organism consumes.

• The role an organism plays in its environment.

• The physical space an organism occupies.

What are biotic factors?

• Geographical features of a habitat.

• Non-living components of an ecosystem.

• Living components that affect the ecosystem.

• Climate conditions of a habitat.

Which of the following is an abiotic factor?

• Temperature

• Grass

• Bacteria

• Lion

What does the competitive exclusion principle state?

• Species can only survive in their original habitat.

• Species must evolve to occupy the same niche.

• Two species cannot occupy the same niche in the same habitat at the same time.

• Two species can share the same niche indefinitely.

What might happen if two species occupy the same niche?

• The niche will expand to accommodate both species.

• Both species will thrive without competition.

• One species will adapt, evolve, or go extinct.

• Both species will merge into one.

Which of the following is NOT a possible outcome when two species compete for the same niche?

• One species evolves to a different niche.

• One species migrates to a new habitat.

• One species goes extinct.

• Both species continue to compete indefinitely.

What is a possible consequence of limited resources in a habitat?

• Increased cooperation between species.

• Unlimited growth of all species.

• Unchanged population dynamics.

• Increased competition between species.

What is the main focus of the video conclusion?

• Explaining the history of ecological research.

• Discussing the future of ecological studies.

• Summarizing the key points about habitat and niche.

• Introducing new concepts about ecosystems.
