A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other.
What are the functions of food web?
Functions of food chain: i) Food chain maintains ecological balance. ii) It helps in converting solar energy into usable chemical energy for various organisms.

What are the food chain and food web explain with the help of one example of each?
A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.
What is ecosystem and function of ecosystem?
The ecosystem is the structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment.
What is ecosystem function?
Ecosystem functions are natural processes or exchange of energy that take place in various plant and animal communities of different biomes of the world. … These exchanges sustain plant and animal life on the planet as well as the decomposition of organic matter and the production of biomass.
What is food chain in ecosystem?
A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. … This site also tells us that because of our eating habits, we are in two food chains- marine and land.
What is food web in ecosystem?
A food web consists of all the food chains in a single ecosystem. … Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
How does the food chain and food web help in flow of energy in an ecosystem?
Food web is an important ecological concept. Basically, food web represents feeding relationships within a community (Smith and Smith 2009). … In a grazing food chain, energy and nutrients move from plants to the herbivores consuming them, and to the carnivores or omnivores preying upon the herbivores.
What are the four functions of ecosystem?
Four important functional aspects of the ecosystem are productivity, decomposition, energy flow and nutrient cycling.
What are the 3 major functions of an ecosystem?
According to Pacala & Kinzig 2002, there are three classes of ecosystem functions: Stocks of energy and materials (for example, biomass, genes), Fluxes of energy or material processing (for example, productivity, decomposition Stability of rates or stocks over time (for example, resilience, predictability).
What are the functions of an ecosystem Class 10?
So, we can say that the functions of the ecosystem are:
- Ecosystem maintains balance among Producers, Consumers and Decomposers.
- It provides an environment for producers to trap sun’s energy and provide food.
- It is responsible for the cycling of nutrients between biotic and abiotic components.
What is an ecosystem and how does it function Class 7?
An ecosystem is a biological community of interacting organisms and their physical environment. Ecosystem Functions are as follows- Three levels of organisms regulate the flow of energy in ecosystems: the producers, the consumers, and the decomposers. They are organized in complex food webs.
What are the 4 types of ecosystems?
The four ecosystem types are classifications known as artificial, terrestrial, lentic and lotic. Ecosystems are parts of biomes, which are climatic systems of life and organisms. In the biome’s ecosystems, there are living and nonliving environmental factors known as biotic and abiotic.
