Answer: Breaks down, decomposes. Decomposers include bacteria and fungi.
<h2>Maternal effect</h2>
Explanation:
In maternal effect the phenotype of the progeny is decided by the genotype of the mother
- The female partner is one step ahead to her male partner
- The ovum transcribes some of its nuclear genes prior to fertilization and these genes are responsible for the development of embryo that is why these genes are called maternal effect genes
- This effect is observed in Drosophila
In the given question both male and female have brown eyes with Nn genotype,phenotype of the offspring will be decided by the genotype of mother(Nn) hence despite of having recessive genotype(nn) all the offsprings will show brown eyes

Fertilization is done by germination of pollen on the pistil, without need of moisture as in the case of ferns (character they share with other Spermaphytes).
In Angiosperms fertilization has three essential characteristics:
* it is siphonogamous: the apertured pollen grain possessing two or three cells sees its vegetative cell germinate and form a pollen tube which will convey, with the help of its cytoskeleton, the male gamete (case of the tricellular pollen) where the generating cell ( case of the bicellular pollen) which will carry out its second division of meiosis. In this siphonogamy corresponds to a total franking of water for fertilization.
* it is anisogamous: the female gamete is by far the most massive of the two (the pollen grain is often very dehydrated, the cells it contains have a very small cytoplasmic space).
* it is double: the male gametes conveyed by the pollen grain will merge their nuclei (caryomixis) with those of two different cells. It's a special function for the reproduction of angiosperms. The pollen grain contains two nuclei (all haploids), whereas for example the mammalian spermatozoa contains only one.
Hypertonic is when the solution has a high concentration (high osmolarity), hypotonic is when the solution has a low concentration (low osmolarity) and isotonic is when the conditions are equal (same osmolarity). When in an hypotonic environment, a cell will take in water, causing it to swell
