Answer:
Energy and nutrients are cycled throughout all the different components of the ecosystem. The non-living components like heat and nutrients are called abiotic factors. Both biotic and abiotic factors contribute to an environment's health. Biotic factors include plant productivity and animal behavior.

Answer:
Meiosis produces four genetically different haploid cells.
Gametic chromosomes have a different combination of alleles than parental chromosomes as a result of independent assortment
Explanation:
Meiosis and Mitosis are two types of cell division that occurs in living organisms. However, Mitosis produces daughter cells that are genetically identical to the parent cell while meiosis produces daughter cells that are genetically different from the parent cell. This accounts for the reason meiosis leads to genetic variation.
The production of genetically different cells by meiosis is as a result of the process of the random orientation of chromosomes during metaphase I of meiosis I. This process is called INDEPENDENT ASSORTMENT. However, crossing over occurs during prophase I of meiosis between non-sister chromatids of homologous chromosomes.
