Write the food chain
Answers
Answer:
food chain is a linear network of links in a food web starting from producer organisms and ending at an apex predator species, detritivores, or decomposer species. A food chain also shows how organisms are related to each other by the food they eat. Each level of a food chain represents a different trophic level.

A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
The food chain also explains the feeding pattern or relationship between living organisms. A Trophic level refers to the sequential stages in a food chain, starting with producers at the bottom, followed by primary, secondary, and tertiary consumers. Every level in a food chain is known as a trophic level.
The food chain consists of four major parts, namely:
The Sun: The sun is the initial source of energy, which provides energy for everything on the planet.
Producers: The producers in a food chain include all autotrophs such as phytoplankton, cyanobacteria, algae, green plants. This is the first stage in a food chain. The producers make up the first level of a food chain. The producers utilize the energy from the sun to make food. Producers are also known as autotrophs as they make their own food. Producers are any plant or other organisms that produce their own nutrients through photosynthesis. For example, green plants, phytoplankton, and algae are some examples of producers in a food chain.
Consumers: Consumers are all organisms that are dependent on plants or other organisms for food. This is the largest part of a food web, as it contains almost all living organisms. It includes herbivores which are animals that eat plants, carnivores which are animals that eat other animals, parasites are those organisms that live on other organisms by harming them and lastly the scavengers, which are animals that eat dead animals’ carcasses.
Here, herbivores are known as primary consumers and carnivores are secondary consumers. The second trophic level includes organisms that eat producers. Therefore, primary consumers or herbivores are organisms in the second trophic level.
Decomposers: Decomposers are organisms that get energy from dead or waste organic material. This is the last stage in a food chain. Decomposers are an integral part of a food chain, as they convert organic waste materials into inorganic materials like nutrient-rich soil or land.
Decomposers complete a life cycle. They help in recycling the nutrients as they provide nutrients to soil or oceans, that can be utilized by autotrophs or producers. Thus, starting a whole new food chain.
