EVERYDAY SCIENCE

Detailed explanation-1: -Autotrophs are able to manufacture energy from the sun, but heterotrophs must rely on other organisms for energy.

Detailed explanation-2: -An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

Detailed explanation-3: -Animals are heterotrophs. They do not possess chlorophyll pigment to undergo photosynthesis, hence they feed on living organisms.

Detailed explanation-4: -Plants convert sunlight into the energy stored in their food. Plants also provide food for others. The plant is then fed to the next part of the food chain. 3 Plants are eaten by animals.

Detailed explanation-5: -All nutritional energy comes from the Sun: plants use chlorophyll to photosynthesize the Sun’s energy into plant energy, and then animals either feed on plants for that energy or they feed on the animals that have eaten that plant energy. The food chain begins with the Sun and then the energy flows to producers.
