Answer:
1. The gametophyte generation is haploid.
2. The embryo is diploid.
3. The megaspore is haploid.
4. The sporophyte generation is diploid.
Explanation:
1. Gametophyte- The gametophytic generation is the structure which produces gametes in the plant. Since the gametes are haploid, therefore, the gametophyte us considered the haploid.
2. Embryo- The embryo is formed after the fusion of fertilization when zygote develops, therefore, is considered diploid.
3. Megaspore- the big size spore which is formed from by the meiotic division of the megasporocyte, therefore, is considered haploid.
4. Sporophyte- the sporophyte generation develops from the embryo which is diploid therefore is considered diploid.

Explanation:
The correct answer is 3- <span>The smelt and alewife may out-compete the native fish by consuming all of the zooplankton.
The diagram tells us that zooplankton is eaten by smelts and alewifes. If these two species increase in number, less of the zooplankton will be left for plankton-eating fish, which is a native type of fish, to eat.
</span>
<span> smelt and alewife eat most of the existing plankton so, they are out-competing the native fish.</span>
