Game: Marine Food Web Words you need to know A food chain shows how each living thing gets energy through its food. Plants get energy from the sun. Some animals eat plants (herbivores), some eat both plants and animals (omnivores) and some animals eat other animals (carnivores). In a food chain, each link in the chain (or food source) becomes food for the next link in the chain. Top level
A food web (or food cycle) is a natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community.
You can also refer to the diagrammatic representations of food chains, food webs and ecological pyramids. A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores.
Polis (1991) – a skeptic of food web theory – characterized desert food webs in great detail: found evidence that 2 or 3 sp loops occur in systems with size-dependent predation.
Food chains and food webs describe feeding relationships. The population of species in a food chain is shown using a pyramid of numbers. Organisms in an ecosystem affect each other’s population.
Individual food chains operate within much larger and more complex networks called food webs. In turn, food webs are one of the main regulators of ecosystem dynamics. They play a role in the way ecosystems respond to natural and human-induced changes.
A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3). In a freshwater aquatic ecosystem like a pond, the organisms in the food chain include algae, small animals, insects and their larvae, small fish, big fish and a fish-eating bird or animal (Figure 8.4).
