Answer 1

The correct option is C 3

Ecosystem is a functional unit of nature, where living organisms interact among themselves and also with their surrounding physical environment.

There are two types of ecosystems based on their formation:

• Natural ecosystems: They develop in nature without human support or interference. Examples include forests, deserts and oceans.
• Anthropogenic or man-made ecosystems: These are created and maintained by human beings. Examples include crop fields, aquariums, and gardens.
  • Crop field ecosystem is a man-made ecosystem, created and maintained by farmers. Agricultural crop fields or agroecosystems are the largest man-made ecosystems. However, it has a much simpler composition with regard to the number of species and the relative simplicity of energy flows compared with a natural ecosystem.
  • Garden is an artificial ecosystem and consists of a community of plants, birds and pollinators that work together to form a balanced ecosystem.
  • An aquarium is a man-made ecosystem in which fishes and plants are able to find a habitat where they can grow and develop in a healthy and balanced way.

Therefore, option c is the correct answer.
