Man made ecosystems are the artificial ecosystems, as they do not possess a self-regulating mechanism. They have almost no diversity and have simple food webs. The cycling of nutrients is negligible. Different artificial or man made ecosystems are crop land and zoo and dams and aquarium. In natural ecosystem the components are created and governed through the biological laws, for example, the predators feed on prey, whereas in artificial ecosystem everything needs to be planned and executed

Man made artificial ecosystem: Agro ecosystem

Agro ecosystem is the man-made artificial ecosystem that is developed by humans for agricultural purposes. It is a system where plants, animals, and microorganisms interact with each other in a controlled environment. Agro ecosystems are designed to produce crops and livestock for human consumption and other uses.

Components of Agro ecosystem:

- Crops: Agro ecosystems consist of various crops such as wheat, rice, maize, and other vegetables. These crops are grown in a controlled environment with the help of fertilizers, pesticides, and other farm inputs.
- Livestock: Animals such as cows, buffaloes, goats, and poultry are also part of the agro ecosystem. These animals are reared for milk, meat, and other products.
- Soil: The soil is a crucial component of the agro ecosystem. It is treated with fertilizers and other inputs to ensure the healthy growth of crops and plants.
- Water: Water is essential for the growth of crops and animals in the agro ecosystem. Irrigation systems are used to supply water to crops in a controlled manner.
- Microorganisms: Microorganisms such as bacteria and fungi play a crucial role in the agro ecosystem. They help in the decomposition of organic matter, nutrient cycling, and soil formation.

Advantages of Agro ecosystem:

- High productivity: Agro ecosystems are designed to maximize productivity and yield. They use modern farming techniques and inputs to produce crops and livestock in large quantities.
- Food security: Agro ecosystems play a crucial role in ensuring food security. They produce enough food to feed the growing population.
- Employment: Agro ecosystems provide employment opportunities to farmers and farm workers. They also generate income for the rural economy.
- Environmental benefits: Agro ecosystems can also provide environmental benefits such as carbon sequestration, soil conservation, and biodiversity conservation.

Conclusion:

Agro ecosystem is a man-made artificial ecosystem that is designed for agricultural purposes. It consists of crops, livestock, soil, water, and microorganisms. Agro ecosystems are highly productive and provide food security, employment opportunities, and environmental benefits.
