LIFE 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: -A food chain always starts with a producer, which is an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis.

Detailed explanation-3: -The original source of energy for all of the Earth is the Sun. This means that all food chains must start with the Sun. Only plants can convert sunlight into food, and the herbivore that consumes the plants gets its energy from the Sun through the plant.
