4. Evidence of Species Interdependence
The animals are entirely dependent upon the
plants for their existence either directly, or
indirectly through other animals which in turn
are vegetarian. An example of the basic group
of vegetarians seen in this study range from
the aphids on the oak leaves to the fallow deer
that browse the vegetation. Such vegetarians
provide food for the next group — the carni-
vores. These again were seen to vary much in
structure and biological position. Some were
small, like the predacious ground beetles and
these in turn may be preyed on by the larger
carnivores such as foxes. A third important
