What best describes a food chain?
A food chain describes a single pathway that energy and nutrients may follow in an ecosystem. There is one organism per trophic level, and trophic levels are therefore easily defined. They usually start with a primary producer and end with a top predator.
How do you describe a food chain for kids?
chain describes the order in which organisms, or living things, depend on each other for food. Every ecosystem, or community of living things, has one or more food chains. Most food chains start with organisms that make their own food, such as plants. This adds nutrients to the soil so that new plants may grow.
What is a food chain describe an example?
The food chain describes who eats whom in the wild. 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.
What is purpose of food chain?
A food chain shows how energy is transferred from one living organism to another via food. It is important for us to understand how the food chain works so that we know what are the important living organisms that make up the food chain and how the ecology is balanced.
What do you need to know about the food chain?
Every living thing needs energy to live and grow. A food chain describes how organisms get energy from eating other organisms. Although a food chain usually shows a line of animals that eat each other, it is really a never-ending cycle that repeats over and over!
How does the food chain explain which organism eats another organism?
A food chain explains which organism eats another organism in the environment. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. This occurs when one organism consumes another organism. It begins with producer organism, follows the chain and ends with decomposer organism.
How is energy transferred in the food chain?
The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. This occurs when one organism consumes another organism. It begins with producer organism, follows the chain and ends with decomposer organism.
How is a food web different from a food chain?
A food chain follows a single path, where animals discover food. But a food web shows different paths, where plants and animals are connected. A food web comprises several food chains. In a food chain, an organism eats a single item, whereas in a food web an organism consumes multiple items.
