FOOD
CHAINS FOLLOW A SINGLE PATH AS
ANIMALS EAT EACH OTHER.
EXAMPLE:
GRASS
(is eaten by a) GRASSHOPPER (which is eaten by) a FROG (which
is eaten by a) SNAKE (which is eaten by a) HAWK
FOOD
WEBS SHOW HOW MANY ANIMALS ARE INTERCONNECTED BY DIFFERENT
PATHS.
EXAMPLE:
TREES
produce acorns which act as food for many MICE and INSECTS.
Because there are many MICE, the WEASELS, SNAKES, and RACOONS,
have food. The insects in the acorns also attract BIRDS, SKUNKS,
and OPOSSUMS. With the SKUNKS, OPPOSUMS, WEASELS and MICE
around, HAWKS, FOXES, and OWLS can find food. They are all
connected!
FOOD
WEBS
show how plants and animals are connected in many ways to
help them all survive. FOOD CHAINS
follow just one path as animals find food.
