The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Soil consists of weathered rocks and decomposed organic material from dead plants, animals, and bacteria. Water is a solvent. As it passes through the water cycle, it dissolves minerals and gases and carries them to the oceans. Living organisms have played many roles in the earth system.
Technological designs have constraints.
Technological solutions have intended benefits and unintended consequences. Safe living involves the development and use of safety precautions and the recognition of risk in personal decisions. Natural environments may contain substances that are harmful to human beings. Maintaining environmental health involves establishing or monitoring quality standards related to use of soil, water, and air. Population, resources, and environments When an area becomes overpopulated, the environment will become degraded due to the increased use of resources.
