Final answer:
Living organisms in our world are connected through ecology, which is the scientific study of interactions among organisms and their environment. The biosphere, which extends from the atmosphere to the bottom of the oceans, supports all living things. Biotic factors refer to living organisms, while abiotic factors refer to nonliving parts of the environment.
Step-by-step explanation:
Living organisms in our world are connected to other organisms in a variety of ways. The branch of biology called Ecology is the scientific study of interactions among organisms and their environment, including relationships between living and nonliving things. All living things on Earth can be found in the biosphere, the portion of Earth that supports life. It extends from high in the atmosphere to the bottom of the oceans. Many different environments can be found in the biosphere. All living organisms found in an environment are called biotic factors. Nonliving parts of an environment are called abiotic factors. For example, whales, trees, and plants are biotic factors. Ocean currents, temperature, and sunlight are abiotic factors.
