Ocean thermal energy conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity.
Abiotic examples include things that are not alive but you will find in an ecosystem such as air, gases, water, sand, stones and rocks.
The abiotic environment includes all the nonliving factors and processes in an ecosystem. 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.iving organisms, such as tree leaves, can become a part of the abiotic environment once they die and have their nutrients absorbed back into the soil. Soil is part of an abiotic environment. A drought can alter the level of nutrients in soil.
