Producers and consumers. A food chain always starts with a producer, which is an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis. A food chain ends with a consumer, which is an animal that eats a plant or another animal.
Similarly one may ask, is a bird a secondary consumer?
A bird's position in the food chain may vary according to what it eats. For instance, when a blue tit eats seeds it is a primary consumer. But when it eats a caterpillar, it is a secondary consumer because the caterpillar has already eaten a plant.
What is the second level consumer?
Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers.
Why are there so few secondary and tertiary consumers?
The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.
