A food web consists of all the different food chains in a particular ecosystem, better presenting the relationship of each living thing to another within that ecosystem. Since one living thing can be a part of multiple food chains, different food chains in a food web interconnect and overlap at different points.Know More
Food webs and food chains are not different ways of understanding the relationship between living things in an ecosystem. Food chains show direct relationships, one possible path for nutrients to take in an ecosystem, while food webs bring all the food chains together.
In a food web, organisms are divided into three trophic levels. These categories divide all living things into producers, consumers and decomposers. Consumers are further subdivided into primary consumers, or herbivores; secondary consumers that eat herbivores; and tertiary consumers that eat secondary consumers. Some ecosystems may have more levels of consumers before the chain reaches its apex, or top predator.
The food web itself connects the different food chains, long or short, and different trophic levels. In a healthy food web, there are an abundance of producers, or autotrophs, many herbivores and a small number of carnivores or omnivores. This composition maintains the balance of the ecosystem and keeps it recycling its biomass, which is the total energy of all the living organisms in the web.Learn More
A food chain is a simple sequence of organisms in which each animal or plant is dependent on the one above or below it. Food webs are more complex than food chains in that they include all organisms that have similar feeding habits. Both food chains and food webs include animals that depend on each other for food.Full Answer >
A food web is a comprehensive map of how energy moves, in the form of food, throughout an ecosystem, while a food chain is one specific path through the web. Most food webs on Earth derive their energy primarily, if not exclusively, from sunlight. That energy is captured by plants via photosynthesis and then distributed to the consumers in the environment.Full Answer >
According to All About Wildlife, the jungle's food web consists of insects who feed on plants, insects who are eaten by spiders, insects who eat spiders, and at least one species of spider that feeds on birds and mice. This food web goes on until it reaches apex predators, who sometimes eat each other. The food web in the jungle is very complex. It is not a linear system.Full Answer >
A food web is a diagram showing which animals eat which other animals in a given ecological community. It also aims to show the transfer or flow of energy and materials, such as sunlight or carbon, that occurs between species via their feeding relationships.Full Answer >
