Do you mean primary consumer?
They may eat rodents, insects, plants etc.
Let me give you an example
Cabbage ---> slug -----> Bird
(Producer) (Primary Consumer) (Secondary Consumer)
A consumer is the one who eats others consumer.
First level consumers eat plants.
A first level consumer eats only plants
A third-level consumer is an animal which eats any animal in the second level category, the only animal that would eat the animal would be a fourth level consumer which is not normally found in a ecosystem. You place a certain level consumer on top of the animal it eats. like a mouse would be a first level consumer, since it eats grass which is a producer, then, the owl whcih eats the mouse would be a second level consumer since it eats that first level consumer, rat.
No first level consumer will eat a mouse because first level consumers don't eat meat. A second level consumer (a carnivore or omnivore) would eat a mouse.
nothing dodo
2nd level consumer is a consumer that is an omnivore or a carnivore that eats the 1st level consumers
The shrimp is a primary consumer. That means that it eats the producer first, then the secondary consumer eats the primary consumer, which in this case is the shrimp.
Well its a Consumer that eats the Producers I guess. Also the Second-level consumers eat the First-level consumers and the Producers The Third-level consumers eat the Second-level consumers,First-level consumers and the Producers which is the Decomposers the plants and the Sun
Primary Consumer
What the second lever consumer eats the first lever consumer, it gets only a little bit of its energy. Say that the first lever consumer has 100 percent of energy, the second lever consumer will come along and eat it then only get 10% of the first level consumer. I don't know if that made any since, but I hope it did(:
a herbivore is a 2nd level consumer it only eats small animals also plants, worms, and birdy nuts.A 3rd level consumer only eats meat meat meat......
