Answer:
C
Explanation:
The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.
The answer is C
The more plants there are, the more consumers there are. If there aren't enough plants, the consumers have no way of getting energy, and therefore cannot survive. The species also matters, because certain species of plants can only be eaten by certain species of consumers.
Answer:
The options
a. New combinations of genes yielding genotypes of greater fitness
b. Few heterozygotes because of underdominance
c. Frequency-dependent selection, leading to fluctuations in fitness
d. Heterozygotes with greater fitness, owing to overdominance
e. A random assortment of genotypes because of genetic drift
The CORRECT ANSWER IS b.
b. Few heterozygotes because of under dominance
Explanation:
In genetics, underdominance (at times called "negative overdominance") is the opposite of overdominance.
It is the selection against the heterozygote, that leads to disruptive selection and divergent genotypes. It occurs in cases of inferior and reduced fitness (As in our case study, it is the different chromosomal fusions and inversions)
of the heterozygotic genotype to the dominant or recessive homozygotic genotype. It is unstable as it causes fixation of either allele.
Another example is the African butterfly species Pseudacraea eurytus, which makes use of Batesian mimicry to avoid predation. This species carries two alleles that gives a coloration that is alike to a different local butterfly species that is harmful to its predator. The butterflies who are heterozygous for this trait are observed to be intermediate in coloration and thus encounter an higher risk of predation and a decrease in the total fitness.

Answer:
<em>The grasshopper competes with the sheep for food, thereby reducing the available quantity and quality of food for the sheep.</em>
Explanation:
In an ecosystem, many organisms rely on the same food source. The success of a particular species in extracting the food source better than another species that needs that same food source can affect the success of population of this other species of animal. If the number of grasshopper in this pasture becomes too much, it might lead to the consumption of a large portion of the pasture by the grasshopper, leading to a reduction in the available food for the sheep. If this happens, the population of the sheep might decline in order to balance the increase in the population of the grasshopper.
