Plants are autotrophs, they capture energy from the sun and convert carbon dioxide into carbohydrates. ... A food chain cannot exist without producers or plants .
Do all food chains start with plants?
All food chains start with energy from the sun. ... Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
Does a food chain always start with plants?
A food chain always starts with a producer . ... Most food chains start with a green plant, because plants can make their food by photosynthesis. A living thing that eats other plants and animals is called a consumer.
What does a food chain begin with?

What is the difference between a food chain and a food web?
A food chain follows one path of energy and materials between species . A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. ... Producers are autotrophs, meaning they produce their own food through photosynthesis or chemosynthesis.
Does a food chain always begin with water?
All food chains start with energy from the sun. ... Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
What is food chain with diagram?
A food chain is a linear diagram showing how energy moves through an ecosystem . It shows only one pathway out of the many possibilities in a specific ecosystem. BiologyFood Chain.
What is food chain and example?
The definition of a food chain is a system where a small animal is the food for a larger animal which, in turn, is the food for an even larger animal. An example of food chain is a fly being eaten by a frog and then the frog is eaten by a larger animal.
What is the first organism in a food chain?
Producers , also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms.
What food chain starts green plants?
A food chain always starts with a producer. This is an organism that makes its own food. Most food chains start with a green plant, because plants can make their food by photosynthesis. A living thing that eats other plants and animals is called a consumer.
What is food chain and food web with example?
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 food chain are humans in?
Omnivores such as humans eat plants and animals from all levels, but a food chain that includes humans has a producer , a primary consumer and humans. Humans are said to be at the top of the food chain because they eat plants and animals of all kinds but are not eaten consistently by any animals.
What are the four levels in a food web?
Organisms can be organized into trophic levels: primary producer, primary consumer, secondary consumer, and tertiary or higher-order consumer . Energy decreases in each successive trophic level, preventing more than four or five levels in a food chain.
What is food web examples?
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. The snake may eat a beetle, a caterpillar, or some other animal.
