Food Chain concept diagram illustration Stock Vector Image Art Biology Diagrams Food Chain With Diagram & Examples, Food Web, Food Pyramid, Energy Pyramid Every living organism on the earth needs energy to grow, move, and survive. The sun is the main source of energy for all the living things. Food contains energy, the food (or energy) can be transferred from one organism to the other organism through the food chains. The starting point of a food chain is a category of organisms called Producers.
Food chains also display what happens when a problem occurs and a producer or consumer is lost. Entire communities can collapse. **Food chains can help scientists learn more about ecosystems and how to help them stay balanced.** Depending on the food chain you are examining, the same organism can be considered to be at more than one trophic Food Chain diagram Features of Food Chain. Most food chains start with the producers. Organisms that make their own food are called producers. Plants, phytoplankton, and organisms that look like plants, like algae, are all examples of producers. The food chain starts when these producers are eaten by other organisms.

The diagram shows how mercury can accumulate in the food chain. In the sea, tiny animals and plants called plankton absorb the mercury compounds. When the plankton are eaten by small fish, the
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). A food chain 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. Typically, a food chain is represented by a diagram where arrows show the direction of energy and nutrients flow. Grazing food chain: The grazing food chain is a type of food chain that starts with green plants, passes through herbivores and then to carnivores. In a grazing food chain, energy in the lowest trophic level is acquired from photosynthesis. In this type of food chain, the first energy transfer is from plants to herbivores.
