Q:

What is a producer in biology terms?

A:

Biologists use the term producer to describe green plants that synthesize food through the process photosynthesis. Producers form the bottom rung of the food chain, and they serve as food for animals, which bear the name consumers. Without producers, the food chain would collapse because all other living organisms depend on them for food.

Plants engage in photosynthesis by combining carbon dioxide and water with sunlight. This process releases a small amount of water, some oxygen as a waste product and sugars. These sugars contain the energy that originated in the sun; when the plant needs energy, it breaks down these sugars to release the energy.

Photosynthesis largely takes place in small organelles, called chloroplasts. Chloroplasts are most common in the cells that make up the plant’s leaves, but a few can also be found in the stems and other green structures. Scientists believe that chloroplasts may have initially evolved as free-living bacteria before they became symbiotic components of some plant cells.

Despite the fact that green plants make their own food, some plants, such as the infamous Venus fly trap, consume animals as well. Carnivorous adaptations are common strategies of plants that live in nutrient-poor environments, such as peat swamps. Despite the ingestion of food, these plants still produce sugars through photosynthesis.

    What do archaebacteria eat?

    A:

    Some archaebacteria are photosynthetic, meaning they make their own food; however, rather than use the pigment chlorophyll like green plants and algae, they employ a light-sensitive purple protein called bacteriorhodopsin. Other archaea live in places where no sunlight penetrates, such as deep-sea thermal vents. These bacteria rely on a process called chemosynthesis to make ATP.

    What is a producer in the ocean?

    A:

    Producers can create their own food; the largest example of a producer is a plant. There are two kinds of plants found in the ocean: microscopic plants that float around and bigger plants that grow from the ground.
