Every living thing—from one-celled algae to giant blue whales—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 rabbit eats the grass. A fox eats the rabbit.
What is food chain give an example class 6?
Theory: In a forest, the deer eats grass, the tiger, in turn, eats the deer. In an ecosystem, there is a chain like relationship present between organisms that inhabit the particular ecosystem. The sequence of living creatures that represent who eats whom in an ecosystem is called a food chain.
What is food chain answer?
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
What is food chain give an example of it Class 5?
Answer: a series of organisms each dependent on the next as a source of food. Example: Grass – antelope – tiger – vulture.
What is food chain and example? – Related Questions
What is food chain short?
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.
What is food chain for Class 4?
A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees and shrubs, the giraffes (that eat trees and shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link.
What is food chain explain with example Brainly?
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.
What is a food chain for class3?
Answer: A food chain is a sequence of events where one organism eats another, and the energy is transferred on. Explanation: The food chain is the order of events in the ecosystem, where the energy and nutrients are transferred from one organism to another.
What is a food chain for grade 1?
What is a food chain first grade?
All living things need energy to live and grow, and the flow of energy from one organism to another is called a food chain. Starting the food chain are producers, which are plants, fruits, and vegetables that make their own energy from the sun. Consumers eat producers and get their energy from them.
What is a food chain Class 7?
(a) The sequence of living organisms in a community in which one organism consumes another organism to transfer food energy is called a food chain. An example of a simple food chain is that operating in a grassland: Grass (Producer)⟶Deer (Herbivore)⟶Lion(Carnivore)
What is a food chain 5th?
Level 1: Plants (producers) Level 2: Animals that eat plants or herbivores (primary consumers) Level 3: Animals that eat herbivores (secondary consumers, carnivores) Level 4: Animals that eat carnivores (tertiary consumers, carnivores) Level 5: Animals at the top of the food chain are called apex predators.
What is a food web for Grade 5?
A food web is a model made of intersecting food chains. Photosynthesis. A process by which plants use sunlight to make sugar from carbon dioxide and water. Producer. A living thing (almost always a plant) that takes energy from the sun and make its own food.
How much energy is passed from one trophic level to another?
Energy transfer between trophic levels is inefficient. Only about 10% of the net productivity of one level ends up as net productivity at the next level. Ecological pyramids are visual representations of energy flow, biomass accumulation, and number of individuals at different trophic levels.
What do Primary consumers eat?
Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else.
What is meant by ecosystem ‘?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscapes, work together to form a bubble of life.
What is ecological factors in business?
Ecological factors are natural forces that shape a macro environment. It is largely shaped by the ease of access to natural resources used in the production and distribution of a company’s goods and services.
What are abiotic and biotic factors?
Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.
Is a biotic factor?
A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem. Learn more about biotic factors with this curated resource collection.
What is a producer’s job in an ecosystem?
Producers convert water, carbon dioxide, minerals, and sunlight into the organic molecules that are the foundation of all life on Earth.
How does energy flow through an ecosystem?
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
