IB MYP Biology food chains and webs Practice Questions Biology Diagrams 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. There is a single path through a food chain. Food chains and food webs are based on the flow of energy and matter from one organism to another. From the producer, energy and matter flow to the consumer(s). Food Web: connection of all food chains in a community. Balance of Life: Food webs and food chains keep living organisms in balance. These interactions keep population numbers in check. A food chain represents a linear sequence in which energy transfers from one organism to another. Each step in the chain involves a transfer of energy from a source, usually the Sun, through various organisms. Food chains start with primary producers, such as plants, and end with top predators or decomposers, which help recycle nutrients back

In ecology, a food web describes the feeding connections between organisms in a biotic community. Both energy and nutrients flow through a food web, moving through organisms as they are consumed by an organism above them in the food web. It is rare to find food chains that have more than four or five links because the loss of energy limits

A food chain is a linear sequence of organisms through which energy and nutrients flow. It outlines a straightforward pathway describing who eats whom in an ecosystem. Typically, a food chain begins with a primary producer, such as a plant, which captures energy from the sun through photosynthesis. Other essential components of a food chain Food-chain length typically is estimated as (1) connectance-based FCL—an average connectance between basal resources and top consumers, (2) functional FCL—by experimental determination of functionally significant effects of a top predator on lower trophic-level biomass patterns, and (3) realized FCL—an average connectance measure weighted

Food Chains in Freshwaters Biology Diagrams

A food web is a graphical depiction of feeding connections among species of an ecological community. Food chain. The food chain is an ideal representation of flow of energy in the ecosystem. In food chain, the plants or producers are consumed by only the primary consumers, primary consumers are fed by only the secondary consumers and so on.
