PREDATOR OR PREY?

ON SAFARI Copy Learning Objectives To Use a combination of Food chains in a habitat to produce food webs To 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: Herbivore Carnivore Predator Prey Consumer Predator 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: Two primary consumers One secondary consumer Explain why all food chains begin with green plants If the Owls and Snakes were killed what would happen to numbers of: Mouse 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.
