a. ____zebra grazing, including sparse grass populations in the dry season

b. _____chestnut seeds when they are rare and acorns are abundant

c._____kids fishing for hungry trout in a pool

d._____baleen whale if krill are homogeneously distributed

e_____lobsters that are eaten by fish unless they find a rock to hide under

Answer 1

A functional response in ecology is the intake rate of a consumer as a function of food density (the amount of food available in a given ecotope). It is associated with the numerical response, which is the reproduction rate of a consumer as a function of food density.They are classified as type I, II, and III

a. 1 zebra grazing, including sparse grass populations in the dry season

b. 3 chestnut seeds when they are rare and acorns are abundant

c. 1 kids fishing for hungry trout in a pool

d. 1 baleen whale if krill are homogeneously distributed

e 2 lobsters that are eaten by fish unless they find a rock to hide under
