Detailed explanation-2: -An environment includes living things such as plants, animals, people, and even the tiniest of microbes. The living portions of the environment are called the biotic parts. The nonliving portions, such as rocks, sunlight, and air, are called the abiotic parts.

Detailed explanation-3: -The interactions between living things and their non living environment makes up a total ecosystem; understanding any one part of it requires knowledge of how that part interacts with the others.

Detailed explanation-4: -Living things need nonliving things to survive. Without food, water, and air, living things die. Sunlight, shelter, and soil are also important for living things. Living things meet their needs from living and nonliving things in ecosystems.
