The components of an ecosystem include

1. The components of an ecosystem are the basic factors that constitute an ecosystem. Any ecosystem includes two subsystems, namely, environmental system and life system. Environment includes solar radiation, humidity, moisture, air and other climatic factors, as well as various inorganic elements and organic compounds (protein, carbohydrates, fats, humus, etc. ); Life system includes producer, consumer and decomposer. Producers mainly refer to green plants and photosynthetic bacteria, such as cyanobacteria and green algae. They can convert solar energy into chemical energy, and synthesize inorganic elements, water and carbon dioxide in the environment into organic substances such as protein, carbohydrates and fats. It is the source of energy for all living things in the world. Without producers, the photosynthetic function and the whole life system of green plants will cease to exist.

2. Green plants are an indispensable part of the ecosystem. Consumers are heterotrophs, which can be divided into herbivores according to their consumption objects, also known as first-class consumers; Carnivores, also known as secondary consumers. Decomposition mainly refers to microorganisms and fungi, but also includes some protozoa and humus. They can decompose complex animal and plant organic residues and animal excreta into water, carbon dioxide and inorganic elements, and return them to the environment for reuse by producers.
