Measurement (mass & weight): Food Chain
Challenge level ⭐
(designed for children with prior knowledge of the Year 3 programme of study)
Learning Objective

Clip Description
A food chain shows the order that living things get their food. Food chains start with plants. Plants make their own food and are called producers. Plants are eaten by animals called primary consumers. The primary consumers are in turn eaten by predators called secondary consumers. When animals die, they become food for beetles, fungi, earthworms and bacteria. These creatures are called decomposers.
In this fascinating clip, the hunting skills of a predator called a sparrowhawk are on show. Sparrowhawks are at the top of a food chain that include sparrows, cabbage white caterpillars and cabbages. How are sparrowhawks able to strike at lightning speed? Watch the clip to find out.
Quick Whiteboard Challenge
A sparrowhawk will eat on average 2 or 3 sparrows each day.
If a sparrowhawk ate 16 sparrows in a single week, how many sparrows might it have eaten on each day of the week?
