19 paź 2023 · The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales (Balaenoptera musculus)—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight.

A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice), or decomposer (such as fungi or bacteria). It is not the same as a food web.
The 4 levels of the food chain consist of: PRODUCERS: At the bottom of the food chain, plants are natural producers and provide food and nutrients to consumers. HERBIVORES: Herbivores (primary consumers) nourish plants and insects. PREDATORS: Predators (secondary consumers) prey on herbivores or other predators.
17 lut 2023 · A food chain refers to a linear sequence of organisms showing how energy or nutrient flows through an ecosystem when one organism consumes another for its survival. It provides information about which species eats which other species in nature.
31 paź 2023 · 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.
Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. Learn more about food chains in this article.
A food chain always starts with a producer. A producer is an organism that makes its own food. Most food chains start with a green plant, because plants make their own food by photosynthesis.
