by producing food that is eaten by animals
no. reptiles are anything that can shed their own skin. even turtles can do it, belive it or not.
[1] Organisms that are eaten by other organisms for food is what makes up the predator-prey relationships of food chains. [2] The food chain begins with food producers. Then it goes to plant-eaters as primary consumers, to meat-eaters as secondary/tertiary/quarternary consumers, to everything-eaters. [3] Examples of a water food chain are phytoplankton as producers, zooplankton as plant-eaters, fish as meat-eaters of each other, and sharks as everything-eaters. [4] Examples of a land food chain are plants as producers, insects as plant-eaters, mammals and reptiles and birds as meat-eaters, and bears as everything-eaters.
No they are not they are herbivorous mammals
Because they break dead organisms down into basic chemicals which can then be used by other organisms to grow and build their bodies, which can then be eaten by other organisms, thus continuing the food chain.
Producers are plants that give us oxygen, and vegetables and fruits. Producers don't eat other producers and organisms, they only get eaten, or used as food by other organisms.
