Victoria Pendred's presentation covers the concepts of food chains and food webs. It begins by defining key terms such as producers, consumers, and decomposers. Producers, like plants, create their own food through photosynthesis. Consumers, such as animals, obtain energy by eating other organisms. Decomposers, like fungi, derive energy from dead matter. The presentation explains how food chains illustrate the flow of energy from producers to consumers, using arrows to show who eats whom. Food webs, more complex than food chains, demonstrate the interconnectedness of various organisms within a community. The presentation uses examples to clarify these concepts.

What is a producer in the context of a food chain?

• An animal that eats plants

• An organism that decomposes dead matter

• A plant that makes its own food

• A consumer that eats other animals

Which of the following is an example of a consumer?

• Sunlight

• Strawberry plant

• Chicken

• Mushroom

What does the direction of the arrow in a food chain represent?

• The eater being eaten

• The flow of water

• The flow of energy towards the eater

• The movement of the sun

What would it imply if the arrow in a food chain diagram pointed from a chicken to a strawberry?

• The chicken eats the strawberry

• The strawberry eats the chicken

• Both are eating each other

• The chicken is eaten by the strawberry

Which organism is an example of a decomposer?

• Grasshopper

• Chicken

• Mushroom

• Fox

What role do decomposers play in an ecosystem?

• They hunt other animals

• They produce their own food

• They eat living plants

• They break down dead organisms

What distinguishes a food web from a food chain?

• A food web illustrates multiple connections and energy flows

• A food web includes only plants

• A food web cannot include decomposers

• A food web shows only one sequence of energy flow

In a food web, what does a green arrow typically represent?

• Sunlight absorption

• Energy flow from plants to animals

• Water flow

• Decomposition process

Which animal in the described food web eats both the grasshopper and the strawberry?

• Fox

• Chicken

• Mushroom

• Grasshopper

Why are food webs considered more complex than food chains?

• They illustrate multiple feeding relationships

• They only include animals

• They are simpler to understand

• They show fewer relationships
