EVERYDAY SCIENCE

Detailed explanation-1: -An ecosystem is a self-contained unit of living things or biotic componenets (plants, animals and decomposers ) and their non-living or abiotic environment (soil, air and water). Abiotic and biotic factors interact with each other to form an ecosystem.

Detailed explanation-2: -Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity. Every factor in an ecosystem depends on every other factor, either directly or indirectly.

Detailed explanation-3: -(A) Viruses – This is the correct answer as they display properties of both living and non-living matter.

Detailed explanation-4: -An ecosystem is a community made up of living and nonliving things interacting with each other. Nonliving things do not grow, need food, or reproduce. Some examples of important nonliving things in an ecosystem are sunlight, water, air, wind, and rocks. Living things grow, change, produce waste, reproduce, and die.

Detailed explanation-5: -An ecosystem consists of a community of organisms together with their physical environment. Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes. In ecosystems, both matter and energy are conserved.
