  • Human Environment: The presence of many communities, families, cultures, political and economic systems, etc., creates the human environment.
  • Natural Environment: The biotic and abiotic elements that make up the natural environment are included. Land, air, water, living things, etc., are a few examples.

Question 12. Why are plants and animals interdependent?

Answer 12. Animals and plants depend on one another for food and the oxygen they breathe. Plants utilise animals’ exhaled carbon dioxide to create food, whereas animals that consume oxygen that plants produce during food synthesis do so to breathe.

Question 13. Give four examples of a human-made environment.

Production was expanded by the industrial revolution and advances in transportation. The development of the communication system sped up and simplified life. People discovered new methods to interact with which further altered their surroundings.

Answer 15. Ravi observed that the sole playground near the school had been dug up as he returned to class after a lengthy break. He was informed that there would be a multi-story structure built there.

Question 18. Give reasons.

  • Man modifies his environment.
  • Plants and animals depend on each other

Answer 18. Reasons for the above are:

  1. Man modifies his Environment: Since the Environment is the fundamental component of life support, man adjusts it to meet his requirements. He changes the landscape by building residences and businesses in which people live and work. The natural system and the habitats of animals have been disturbed by human usage of fossils for personal development.
  2. Plants and animals depend on each other: Because plants are producers and animals are consumers, they mutually depend on one another. Humans breathe in the oxygen plants release into the atmosphere and exhale carbon dioxide, which helps plants to make their food.
