Food Chain Roles and Organisms

Mrs. Balatash reviews worm habitats and a wheat seed experiment, explaining earth systems and complete systems. She introduces food chains, detailing producers, consumers, and decomposers. An owl food chain is used as an example, highlighting the roles of field grass, voles, and owls. Students are instructed to document the food chain in their science journals.

What are the four spheres included in the worm habitats?

• Hydrosphere, Geosphere, Biosphere, Atmosphere

• Lithosphere, Atmosphere, Hydrosphere, Cryosphere

• Biosphere, Lithosphere, Atmosphere, Cryosphere

• Geosphere, Hydrosphere, Lithosphere, Atmosphere

Why did the wheat seeds in the transparent bag remain green?

• They were exposed to sunlight

• They were in a sealed environment

• They were watered daily

• They were kept in a dark closet

What is the primary role of producers in a food chain?

• To decompose dead matter

• To hunt and eat prey

• To consume other organisms

• To absorb sunlight and produce food

Which of the following is a consumer that only eats plants?

• Herbivore

• Omnivore

• Carnivore

• Decomposer

In the owl food chain, what role does the vole play?

• Decomposer

• Herbivore and prey

• Apex predator

• Producer

What is an apex predator?

• An organism that makes its own food

• A plant that absorbs sunlight

• The top predator in a food chain

• An organism that decomposes matter

What do decomposers do in a food chain?

• They produce food from sunlight

• They are the top predators

• They break down dead plants and animals

• They consume only plants

What is the difference between autotrophs and heterotrophs?

• Both consume other organisms

• Both make their own food

• Autotrophs make their own food, heterotrophs consume other organisms

• Autotrophs consume other organisms, heterotrophs make their own food

Which of the following is an example of an autotroph?

• Vole

• Oak tree

• Mushroom

• Lion

Which term describes organisms that cannot make their own food?

• Photosynthesizers

• Autotrophs

• Producers

• Heterotrophs
