Lesson 1 – How Do Environmental Changes Affect Organisms?
We learned that the environment is all of the living and nonliving things in nature. All living things depend on their environment for food, air, and water and a safe place to live. In this way, every living thing on earth is connected. Living things that interact with each other form a community. A community of living and the nonliving things around them are called an ecosystem. Bees, birds, flowers, soil, water, and sunlight are all part of an ecosystem. The nonliving environment includes the streets, buildings, bridges, and cars.
