I'm a bit confused by the plants on the floor one.
Plants on a Forest Floor: Competition
Explain Interaction: The plants on the forests floor compete with each other for the same resources. Both may not receive enough of those resources. Note: When I was around Middle School and High-school I was only taught mutualism, commensalism, and parasitism, so let me know if competition is not a choice your teacher gives you to choose from or wasn't taught to you
Flea bites human: Parasitism
Explain Interaction: The flea drinks the persons blood as food and the person is hurt. Flea bites can be itchy and become painful. Fleas may also also carry disease.
Clownfish in Anemone: Mutualism (although I hear some people say commensalism)

When earth worms bring fine rocks to particles they do it in mechanical weathering
Answer:
<h3>Genotype frequencies</h3>
25% DD
50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
<h3>Phenotype frequencies</h3>
75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d <em>Dd dd</em>
<em />
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)
