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
FOOD CHAIN (Activity 3)Define the following terms:
a) Herbivoreb) Carnivorec) Predatord) Preye) Consumerf) Predator g) Prey
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.

Learning ObjectivesTo explain how variation has benefits
and limitations for survival of organisms in specific habitats
ENDANGEREDExplain why 7 spotted ladybirds are becoming
less common
