Native shellfish populations have dramatically decreased as they are outcompeted by the crabs, causing a decrease in biodiversity.

Scales provide protection, they have lungs for breathing air, internal reproduction allows them to reproduce on land.
Answer: Likewise in pteridophytes, species also produces haploid spores through haploid stage. In diploid stage the two spores fuse together to form a prothallus which is a diploid stage. Hence, the similarity in the reproductive cycle of fungus and a pteridophyte is that both organisms produce haploid spores and exhibit diploid and haploid stages.
Explanation:
Oh, we actually did a similar project in my biology class!
I looked at your punnet squares and they all looked right to me, so I will just explain how to find the genotype and phenotype.
Ok, so let me explain that for genotype they mean the letters, so for example if the penguin has a dominant trait, the genotype could be Ff, or recessive could be ff. By phenotype they mean the trait expressed, so if the penguin is dominant for freckles, the phenotype would be has freckles.
Now I don't know what your teacher wants you to do, but in my class we just flipped a coin to decide whether we would use the dominant or recessive trait.
Hopefully that clears it up a little bit for you :)
