As a result of these processes, the single celled organism accomplishes
1)gamete production
2)energy production
3)sexual reproduction
4)asexual reproduction

The correct answer is option 4 (asexual reproduction).

Explanation:

Asexual reproduction is a type of reproduction in which an organism produces genetically identical offspring's to the parents without involving contribution of genetic material of another individual. It is primary form of reproduction for single-celled organisms.

Mechanism of asexual reproduction involves:

1. Nuclear division- marked by the synthesis of DNA and

2. Cytokinesis- marked by the division of the cell into two identical daughter cells.

Asexual reproduction do not involve fertilization, reduction in chromosome and meiosis.

So, exact copies of parent cells are produced with identical genetic material content.

Thus, option 4-asexual reproduction is the correct answer.

1. a tropical dry forest carries out more rapid nutrient cycling

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
