What Is Meant By A Primary Consumer Secondary Consumer And A Tertia Here, the producers are consumed by the predators primary and secondary consumers and then the detritivores and finally by decomposers. when many such individual food chains occur in an ecosystem, it is known as food web. a food chain shows a direct transfer of energy between organisms. as every organism can feed on multiple things, a food web. The first consumer in the chain is also called the primary consumer. the next one is the secondary consumer. the one after that is the tertiary consumer here is an example of a food web:.
Food Chains Producer Primary Consumer Secondary Consumer Tertiary 5 min read. the main difference between primary secondary and tertiary consumers is that primary consumers are the herbivores that feed on plants, and secondary consumers can be either carnivores, which prey on other animals, or omnivores, which feed on both animals and plants, whereas tertiary consumers are the apex predators that feed on both. Food chains. a food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher level consumers, and finally decomposers. these levels are used to describe ecosystem structure and dynamics. A food web is a graphic representation of a holistic, nonlinear web of primary producers, primary consumers, and higher level consumers used to describe ecosystem structure and dynamics ( figure 19.1.1 ). figure 19.1.1: example of simplified food chains (a) and food webs (b) of terrestrial and marine ecosystems. However, with the help of evolution and new technology, humans are now considered the ultimate tertiary consumer. what is unique about secondary consumers is that they can sometimes also be considered primary or tertiary consumers depending on the environment. for example, when squirrels eat nuts and fruits, it is a primary consumer.
