Structure of Ecosystem
The organization of biotic and abiotic components characterizes the structure of an ecosystem. This involves the circulation of energy in our environment. It also involved the environmental conditions present in that particular environment. There are two components of the ecosystem those are:
- Biotic Components
- Abiotic Components
Biotic Components
The living components of an ecosystem are referred to as the biotic components. These biotic components can be divided and categorized based on the source of energy requirement The three main groups of biotic components are producers, consumers, and decomposers. Biotic elements can be divided into autotrophs, heterotrophs, and saprotrophs based on their nutritional needs.
- Producers are the plants in the ecosystem which can produce their own energy requirement through photosynthesis, in the presence of sunlight and chlorophyll, and are referred to as autotrophs. Consequently, all other organisms are dependent on plants for their energy needs of food as well as oxygen.
- Consumer are referred to as heterotrophs because organisms depend on other organisms for food. Consumers are – herbivores, carnivores, and omnivores.
- Herbivores are living organisms that feed on plants.
- Carnivores consumed other living organisms.
- Omnivores are animals that can consume both plant and animal tissue.
- Consumers are usually categorized into primary consumers, secondary consumers, and tertiary consumers.
- Primary consumers constantly serve as herbivores as they depend on producers for food.
- Secondary consumers mostly depend on primary consumers for energy. It can either be carnivores or omnivores.
- Tertiary consumers are organisms that mostly depend on secondary consumers for food. It can also be carnivores or omnivores.
- There are quaternary consumers present in some food chains. For energy, these organisms feed off tertiary consumers. Additionally, because they have natural predators, they are frequently at the top of a food chain.
- Decomposer are the fungi and bacteria, which are the saprophytes. They are a breakdown of organic matter it consumes the decomposing organic material and transforms this matter into nitrogen and carbon dioxide. The saprophytes play a crucial role in recycling the nutrients so that the developed is that plants can use them once again.
Abiotic Components
The ecosystem’s non-living components are known as abiotic components. These are additionally referred to as ecological factors. The environment is characterized by its physical and chemical elements. The abiotic components of an ecosystem include things like light, air, soil, and nutrients.
CBSE Class 10 Chapter 13 Our Environment Notes
The environment includes all living and non-living factors that interact in a particular area. The class 10 CBSE ‘Our Environment’ notes show that the environment consists of both biotic and abiotic factors. The biotic factors include living components including plants, animals, etc whereas the abiotic factors include non-living components like air and sunlight. These ‘our environment’ class 10 NCERT notes clearly explain how these components help sustain life on Earth.
