If a grasshopper is eaten by a frog, then the energy transfer will be from :
(a) producer to decomposer
(b) producer to primary consumer
(c) primary consumer to secondary consumer
(d) secondary consumer to tertiary consumer
(c) primary consumer to secondary consumer
A grasshopper eats grass; hence, the grasshopper is the primary consumer. A frog eats the grasshopper, so the frog becomes the secondary consumer. The energy transfer is from the primary consumer to the secondary consumer, i.e., from the grasshopper to the frog.
