Answer:
a.) Two producer are land plants and tiny water plants.
b.) Two consumers are fox and heron.
c.) tiny plants → water fleas → diving beetle → small fish → perch → heron.
(I think this is correct because there are six species listed and they go in order.)
d.) The small fish eats the water fleas and diving beetle.
e.) The heron and perch eat the small fish.
f.) If the frog disappeared there may be a lower population of fox and heron in that area, and there would be more slugs, insects, and diving beetles.
