Question

identify a food chain that consists of a producer, a primary consumer ,a secondary consumer , and a tertiary consumer?

Answer 1

marine ecosystems are great examples of this
here's an example of a lake ecosystem's food chain
producer: phytoplankton
tiny organisms that photosynthesize
primary consumer: very small fish, like sunfish
secondary consumer: larger fish, like bass
tertiary consumer: fish predators, like a bald eagle or osprey

Answer 2

Food chain can be defined as the the sequence of events in which one organism feed over the other that results in maintenance of ecological balance.

Grassland biome is a good example of food chain that involves producer, a primary consumer ,a secondary consumer , and a tertiary consumer, such as grass or plants are the producers (photosynthetic) which make their own food with the help of sunlight, grasshopper feed over grass, so grasshopper is a primary consumer (Herbivores), mouse eat grasshopper and become secondary consumer (Carnivore) and snake feed over mouse and become tertiary consumer, and snake can be eaten by Hawk, which become Quaternary Consumer.
