EVERYDAY SCIENCE

Detailed explanation-1: -All food chains start with energy from the sun. This energy is captured by plants. 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.

Detailed explanation-2: -They are able to use light energy to synthesize their own food. In the case of plants, the excess food is stored in different parts which is then utilized by other organisms like herbivores. So, starting points of all food chains, except detritus food chains, are autotrophs i.e plants.

Detailed explanation-3: -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.

Detailed explanation-4: -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.

Detailed explanation-5: -All food chains begin with the sun because the sun provides the energy which primary producers use to create biomass. This energy is supplied in the form of light and the light is absorbed by primary producers and used to perform photosynthesis.
