PREDATOR OR

PREY?

ON SAFARICopy Learning Objectives

To Use a combination of Food chains in a habitat to produce food websTo explain energy transfer in food webs and relate this to the abundance of organisms

Note keywords: Practice using them to answer questions

PREDATOR OR PREY?You task is to identify predator and prey animals in the

pictures below

FOOD CHAIN (Activity 3)Define the following terms:

a) Herbivoreb) Carnivorec) Predatord) Preye) Consumerf) Predator g) Prey

What is a food Chain?

FOOD CHAIN The food chain shows us what eats what in a

community.

They show the movement of FOOD ENERGY from one organism to the next.

FOOD CHAIN

From the food-web above, name:a) Two primary consumersb) One secondary consumerc) Explain why all food chains begin with green plantsd) If the Owls and Snakes were killed what would happen to numbers of:

Mousee) If the snakes were killed what would happen to the population of kite?

What is a food Chain?

Every living thing needs energy in order to live. Animals get energy from the food they eat, and all living things

get energy from food. Plants use sunlight, water and nutrients to get energy (in a process called

photosynthesis).

FOOD CHAIN

A food chain is the sequence of who eats whom in a biological community (an

ecosystem) to obtain nutrition.

HOMEWORK

EARTH

Learning ObjectivesTo explain how variation has benefits

and limitations for survival of organisms in specific habitats

Habitats

What is an habitat?

Give examples of habitats

ADAPTATIONS

Savannah Habitat

Arctic Fox lives in ……..

Fennec Fox Lives in …..

SURVIVAL

ENDANGEREDExplain why 7 spotted ladybirds are becoming

less common
