In the alteration of generations life cycle the spore undergoes mitosis to become a A) gametophyte B) sproohyte C) spore D) game
Eva8 [605]
<span>A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation. The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.</span>

Yuri [45]

Answer:

Overfishing is one of the major concern no a days in aquatic systems. overfishing is resulting in the extinction of aquatic organisms and it can lead to several damage to other living organism.

Prawns and small fishes are important organisms in food web or in aquatic system as they maintain the bacterial level or other microorganism level in control.

Prawn and small fishes utilize oxygen and nutrients present in water to survive, if they will get extinct the amount of nutrient and oxygen left will be used by the bacteria and mold living in the system which can have bad impact on human and other organism.

Heron and pelican populations depends on prawn and small fishes for survival as they feed on them and when there will be not sufficient population of  prawn and small fishes, there are chances that heron and pelican populations can also get extinct.
