Food Chain Dynamics and Relationships

Dr. Life explains the concepts of prey and predator, illustrating with examples like zebras and lions. The video then delves into the food chain, describing how energy is transferred from producers to consumers. It concludes with identifying prey and predator roles within a food chain, using examples to clarify these relationships.

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

• To decompose organic matter

• To produce energy

• To hunt and eat other animals

• To consume plants

Which animal is considered the prey in the example given?

What does a food chain always start with?

• A decomposer

• A predator

• A consumer

• A producer

In a food chain, what does the arrow represent?

• The speed of the predator

• The size of the organism

• The lifespan of the prey

• The direction of energy transfer

Which organism is the producer in the given food chain example?

• Prawn

• Lion

• Zebra

• Eagle

In the food chain example, which organism is a predator of B?

• A

• B

• D

• C

What is the relationship between C and D in the food chain?

• C and D are both producers

• D is a prey of C

• C is a prey of D
