Answer: The amount of fertilizer runoff coming from lawns

An abiotic factor is a non-living component of the ecosystem. A list of abiotic factors includes water, sunlight, soil, atmosphere, temperature, wind, climatic conditions and chemical elements. These abiotic factors directly or indirectly affects the biotic or living components of the ecosystem.  A housing development is situated near a river that flows into a bay. Here, fertilizer is a abiotic factor which is being runoff from lawns because fertilizers usually contains chemicals that can contaminate the water of the bay. The chemicals present in the fertilizers can be consumed by aquatic animals hence, can have detrimental effect on them.    

Therefore, the amount of fertilizer runoff coming from lawns is an abiotic factor on land that would directly affect the marine ecosystem in the bay.

You would expect to find that as the generations pass, the offspring of the Bone-gnawers would have short, wide mouths and strong chewing muscles. The Non-gnawers would have longer, narrower mouths, and weaker chewing muscles. This is because the offspring would inherit the parent's traits, and this would lead to eventual less genetic diversity as the two groups of coyotes inbred more and more. (Sorry if I went further than needed, just trying to be thorough! I really hope that this helps!)

Is Female A, Homozygous or Heterozygous... also how do I find it out. Ty :3
Tomtit [17]
First we have to figure out whether the allele controlling for that trait is dominant or recessive. From female A, the pedigree indicates that she shows the trait, but neither of her parents shows the phenotype of the trait. Female A is only possible to have the trait showed if both of her parents carry an allele of the trait. So, that allele for controlling the trait should be recessive and their parents are heterozygous as neither of the parents shows it in their phenotype.

After we figured out the allele is recessive, we can easily determine the genotype of female A. Traits that are controlled by recessive alleles can only be shown in phenotypes if theres no dominant allele existing. Therefore, the genotype of female A must be both recessive, and that means she's homozygous (recessive).

<em>"No man is an island.” This saying is also true for organisms in an ecosystem. No organism exists in isolation.  Individual organisms live together in an ecosystem and depend on one another.  In fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival. </em>

<em>So what do these interactions look like in an ecosystem? One category of interactions describes the different ways organisms obtain their food and energy. Some organisms can make their own food, and other organisms have to get their food by eating other organisms. An organism that must obtain their nutrients by eating (consuming) other organisms is called a consumer, or a heterotroph. While there are a lot of fancy words related to the sciences, one of the great things is that many of them are based on Latin or Greek roots. For example, heterotroph becomes easier to remember when you realize that in Greek, “hetero” means “other” and “troph” means food; in other words, heterotrophs eat other organisms to get their food. They then use the energy and materials in that food to grow, reproduce and carry out all of their life activities. All animals, all fungi, and some kinds of bacteria are heterotrophs and consumers. </em>
