Question

How do producers make their own food?

Answer 1

Hint: Autotrophs are usually the producers. They produce their own food using sunlight, water and carbon dioxide. Autotrophs use a process called photosynthesis to make their food.

Complete answer:
Photosynthesis is the process by which primary producers like plants make their own food.
Steps involved in photosynthesis:
1)Green parts of plants (mostly leaves) absorb light from the sun.
2)Leaves of plants also absorb carbon dioxide from the air.
3)Leaves of plants also absorb water from the ground with the help of their roots. Rain water and groundwater are main sources of water in the process of photosynthesis for terrestrial plants.
4)Leaves of plants capture light from the sun to turn carbon dioxide and water into glucose and oxygen. Glucose is a form of carbohydrate that plants use for food and it helps them to grow and Oxygen is the gas that is used by humans for breathing.

The food that producers (plants) make is glucose. Producers make food for all other levels of the ecosystem. Energy is consistently captured by producers, this energy is passed on to the organisms that eat the producers, and then to the organisms that eat those organisms and so on.

Note: The survival of every ecosystem is dependent on the producers. Without producers capturing the energy from the sun and turning it into glucose, an ecosystem could not exist. Plants are dominant producers on land. Phytoplanktons are the dominant producers in the oceans and lakes. Algae is one of the major examples of phytoplankton.
