Abiotic and Biotic Factors in Ecosystems

The video introduces young scientists to the concept of living things and their environments. It explains that organisms live in habitats, which provide essential resources like food, water, and shelter. Habitats are influenced by biotic factors (living things) and abiotic factors (non-living things). The video further explores levels of organization, from individual organisms to populations and communities, culminating in ecosystems. An ecosystem includes all living and non-living elements an organism interacts with. The video concludes by summarizing these concepts, emphasizing the interconnectedness of life and environment.

What is a habitat?

• A group of the same species living together.

• A place where organisms can find food, water, and shelter.

• A type of plant that grows in the forest.

• A non-living factor that affects organisms.

Which of the following is a biotic factor?

• Sunlight

• Water

• Plants

• Soil

What are abiotic factors?

• Living components in a habitat.

• Non-living elements like water and temperature.

• Groups of the same species.

• Interactions between different populations.

What is the first level of organization in a habitat?

• Community

• Ecosystem

• Population

• Organism

What is a population?

• Interactions between different communities.

• A group of the same species living together.

• A single living organism.

• All living and non-living things in a habitat.

What defines a community in ecological terms?

• A single organism.

• Populations of different species interacting.

• Non-living components of a habitat.

• A group of the same species.

What is an ecosystem?

• All living and non-living components in a habitat.

• Only the non-living elements in a habitat.

• A group of the same species living together.

• Only the living organisms in a habitat.

Which of the following is NOT part of an ecosystem?

• Rocks

• Temperature

• A single organism

• A single type of plant

How do communities relate to ecosystems?

• Communities are smaller than ecosystems and include only living things.

• Communities are larger than ecosystems and include non-living things.

• Communities are the same as ecosystems.

• Communities are part of ecosystems, including interactions among living things.

What role do abiotic factors play in an ecosystem?

• They have no impact on living organisms.

• They are the primary source of food for organisms.

• They provide the living conditions and resources for organisms.

• They are the main predators in an ecosystem.
