Answer:
Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (lithosphere), or evaporating into the air (atmosphere). Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (lithosphere) to produce electricity.
Explanation:
Meiosis is the mechanism used for producing gametes in multicellular organisms whereas it does not play any role in unicellular organisms.
Meiosis produces gamete, or sex, cells and occurs only in multicellular organisms.
Mitosis produces somatic, or body, cells and can occur in both multi and uni cellular organisms.
