Detailed explanation-1: -Land plants, or autotrophs, are terrestrial primary producers: organisms that manufacture, through photosynthesis, new organic molecules such as carbohydrates and lipids from raw inorganic materials (CO2, water, mineral nutrients).

Detailed explanation-2: -Plants as Primary Producers. Plants are the school example of a primary producer. Plants produce energy-rich molecules through a process called photosynthesis. They use water, carbon dioxide, minerals, and sunlight to create their own energy (food).

Detailed explanation-3: -Primary producers-plants, algae, and bacteria-make up the base of the pyramid, the first trophic level. Through a process called photosynthesis, producers capture energy from the sun and use it to create simple organic molecules, which they use for food.

Detailed explanation-4: -Autotrophs or primary producers are organisms that acquire their energy from sunlight and materials from nonliving sources. Algae, higher plants, and some bacteria and protists are important autotrophs in running waters. Heterotrophs obtain energy and materials by consuming living or dead organic matter.

Detailed explanation-5: -The primary producers include green plants, lichens, moss, bacteria, and algae.
