Question

storks are a species of bird that only has the time and energy to provide for one chick. storks lay two eggs. after the eggs hatch, the birds feed both chicks for a week. after a weeks time, the smaller chick is thrown out of the nest and left to fend for itself. from then, the parents focus their efforts only on the larger chick. which stork do you think will be selected against? answer here which trait is favorable? why? answer here what are the variations in this population? answer here how does this species overproduce? answer here how will this species change over time? answer here

Explanation:

1. The smaller chick will be selected against as it is thrown out of the nest and has to fend for itself without parental support, reducing its survival chances.
2. The favorable trait is being larger. This is because larger chicks are more likely to receive parental care and resources, increasing their survival and reproductive success.
3. Variations in the population include differences in size (larger and smaller chicks), which could be due to genetic and environmental factors like differences in egg - nutrition or incubation conditions.
4. This species overproduces by laying two eggs when it can only effectively care for one chick. This increases the probability that at least one chick will survive to reproduce.
5. Over time, the population may evolve to have more larger - sized chicks on average. Since larger chicks have a higher survival rate and are more likely to pass on their genes, the genes associated with larger size may become more prevalent in the population.

Answer:

1. The smaller chick.
2. Being larger; because it gets parental care.
3. Differences in size of chicks.
4. By laying two eggs but only caring for one.
5. More larger - sized chicks may be present in the population over time.
