A food chain is a list of organisms in a. habitat. that shows their feeding relationship, i.e what eats what. The organisms are joined by arrows which show the transfer of energy in food...
Nov 3, 2023 · A food web is a network of interconnected food chains. Food webs are more realistic ways of showing connections between organisms within an ecosystem as animals rarely exist on just one type of food source. Food Web Diagram. A food web shows the interdependence of organisms.

Producers or autotrophs make up the first trophic level of the food chain. They prepare their own food from sunlight, carbon dioxide, and water through photosynthesis. All other organisms in the ecosystem use them for food. Although green plants are the most abundant autotrophs on Earth, algae, phytoplanktons, and autotrophic bacterialiving in volc...
The second trophic level consists of herbivores that depend on producers for food. Cow, deer, elephant, and mice are primary consumers in the grassland ecosystem that consumes grasses, shrubs, and trees. In contrast, many fish and turtles are herbivores in the ocean ecosystem that eat algae and seagrass. In forests, sea urchins act as primary consu...
Secondary consumers are the organisms that reside on the third trophic level and depend on primary consumers for food. They can be carnivores or omnivores. Carnivores eat other animals, whereas omnivores eat both plants and animals. In a desert, a snake is a secondary consumer, eating mice. At the same time, in forests, sea otters are secondary con...
Tertiary consumers eat secondary consumers and are found at the last or the fourth trophic level. In deserts, an owl or an eagle is a tertiary consumer eating a snake. There are more levels of consumers above the tertiary consumers. Apex consumers residing at the top of the food chain are organisms that feed on other consumers for food. Such organi...
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web.
