Question

Green plants are also called as?

Answer 1

Hint: They initiate ecosystem activity. They do not depend on organic matter for nourishment. They utilize the sun's energy directly with the help of chlorophyll and synthesize organic compounds from simple inorganic substances such as water, carbon dioxide and minerals.

Complete step-by-step answer:
The green plants are also known as photoautotrophs. They with the help of their chlorophyll trap the light energy of the sun and change it into the chemical energy of a simple carbohydrate, glucose, produced by them from simple inorganic compounds namely carbon dioxide and water. The process is called photosynthesis. From the basic organic material glucose, the plants then form complex organic compounds such as starches, proteins and lipids. The producers utilize the self-made organic compounds for building up their bodies and short producing energy to operate the metabolic processes. As the green plants and other green organisms prepare their own food themselves with the help of sunlight they are known as the photoautotrophs. Producers dominate the terrestrial ecosystems being the most abundant and massive of all groups of organisms there. These organisms are also termed as producers. These may be herbs, shrubs, large size trees or free-floating microorganisms called phytoplankton. These phytoplankton are usually not noticeable unless present in great abundance when they make the water look greenish. The phytoplankton is more important as the food producers for the pond community than the large plants.

Note: Producers also play an important role in maintaining the carbon dioxide-oxygen balance in nature. The use of carbon dioxide and release oxygen during photosynthesis. Producers are also called transducers because the energy trapped in photosynthesis is the radiant energy of the sun and is changed into chemical energy of organic compounds synthesized by them. Conversion of energy from one form to another is called transduction.
