Food Chains and Webs Concepts

The video tutorial introduces the concepts of predators, prey, food chains, and food webs. It explains how energy is transferred through a food chain, with examples of predators and prey. The lesson also covers the complexity of food webs, where animals are part of multiple food chains. Practice questions are included to reinforce learning.

What is the primary focus of today's science lesson?

• Plant photosynthesis

• The solar system

• Predator and prey relationships

• The water cycle

Which of the following is an example of a predator?

• Zebra

• Grass

• Rabbit

• Lion

In a food chain, what happens to most of the energy?

• It is converted into water

• It is stored in the organism's body

• It is completely transferred to the next organism

• It is lost as waste or used for life processes

Why do carnivores need to eat many herbivores?

• Because herbivores are very large

• To get enough energy due to energy loss at each link

• Because herbivores are scarce

• To maintain their body temperature

What is a food web?

• A network of interconnected food chains

• A diagram of plant growth

• A map of animal habitats

• A single food chain

Which animal is part of the food web example given in the lesson?

• Elephant

• Kangaroo

• Giraffe

• Tiger

What is an example of a consumer that produces honey?

• Ant

• Bee

• Butterfly

• Wasp

What must a food chain always start with?

• A plant

• A herbivore

• A predator

• A carnivore

Which of the following is a producer in a food chain?

• Lion

• Rabbit

• Plant

• Fish

What role does a plant play in a food chain?

• Prey
