Sunlight, soil, water, and pollution, for example, are all important abiotic factors of an environment that affect life. The biotic environment, on the other hand, is composed of all the living organisms in an ecosystem, and includes factors such as disease, predators, prey, and human activity.
the organisms? GRADE-LEVEL EXPECTATIONS: 1. Living and nonliving things interact in land and water environments called ecosystems. Every ecosystem has certain conditions (âabiotic factorsâ) and a variety of living things (âorganismsâ) that are adapted for survival in those conditions. Abiotic factors include the quality and amount of air, sunlight, water and soil, as well as the terrain and climate. 2. Organisms depend on other organisms and on the nonliving things in an ecosystem to meet their basic needs for food, water and protection. 3. Plants use energy from the sun to produce their own food from air and water. The type of soil, amount of water and temperature range in an area determine the plants that grow there. 4.
