Answer 1

Producers are self-feeding organisms that make their own food from inorganic matter (not usually found in living things).

Question 2

2- Do all producers rely on sunlight energy to make their own food?

Answer 2

Some producers rely on the sunlight energy to make their own food by a process called photosynthesis. Other producers, such as some types of bacteria, use certain chemicals to create their own food by a process called chemosynthesis.

Question 3

3- Give examples of producers.

Answer 3

Producers include plants, green bacteria, bacteria found in hydrothermal vents, algae and phytoplankton (microscopic marine algae).

Question 4

4- Describe the process of Photosynthesis.

Answer 4

During Photosynthesis, the producer uses sunlight energy to make its own food which is glucose (sugar) and oxygen from water and nutrients from the soil and carbon dioxide from air.
