You have come to the
end of this Discovery Trail. Did you realise that the trail was following a food chain in
the wetlands? (The Wetlands Discovery Trail starts here!)
A Food Chain shows how things eat each
other in turn. A Food Chain is shown as a line, with arrows connecting together the things
which are eating each other. The arrow always points towards the one which is doing the
eating. Most Food Chains start with plants. These are eaten by plant-eaters (herbivores),
which are then eaten by meat-eaters (carnivores). For example:
Grass Rabbit
Fox
The example given above is a very simple
food chain with only one carnivore. However, food chains will usually have carnivores
eating other carnivores, so there may be 5 or 6 different things in the food chain.
Now see if you can pick out the food
chain which you followed, from the four examples (A,B,C & D) shown below.
Remember that for a Food Chain to work,
each part of the sequence must be correct. In the examples below the initials GDB stand
for Great Diving Beetle. |
