evaluate: cause of migration claims

1. what causes wildebeest migration in serengeti national park.

claim- circle the claim below that best answers question 16 above.
a. disease is the main cause of wildebeest migration in the serengeti
b. predation is the main cause of wildebeest migration in the serengeti
c. food is the main cause of wildebeest migration in the serengeti
evidence- provide at least 2 pieces of evidence from todays lesson to support your claim. be sure to use both qualitative and quantitative data to support your claim.
reasoning- how does the evidence you listed explain your claim?

Explanation:

• Qualitative evidence: Wildebeests are herbivores that rely on grass as their primary food source. In Serengeti, the grass availability is seasonal. When one area’s grass is depleted (due to consumption or seasonal dry - out), they move to areas with fresh grass.
• Quantitative evidence (example, assuming data from a lesson): If in a dry season, a 10 - square - kilometer area in Serengeti has only 20% of its usual grass cover (quantitative measure of food scarcity), and during this time, a herd of 10,000 wildebeests (quantitative measure of population) migrates to a region with 80% grass cover (another quantitative measure of food availability).

The evidence shows that wildebeests move in response to food (grass) availability. The qualitative aspect is their herbivorous nature and the seasonal nature of grass growth, while the quantitative data (hypothetical, as no actual data is given in the problem but following the requirement) shows the numerical relationship between food scarcity/abundance and migration.

Answer:

• Evidence:
• Qualitative: Wildebeests are herbivores depending on grass. Serengeti has seasonal grass availability.
• Quantitative (example): In dry season, Area A has 20% grass cover (food scarcity), and 10,000 wildebeests migrate to Area B with 80% grass cover (food abundance).
• Reasoning: The qualitative evidence establishes the basic relationship between wildebeests (herbivores) and their food (grass). The quantitative evidence (using made - up but relevant numbers) shows a numerical correlation between food availability (grass cover percentage) and the wildebeest migration (number of wildebeests moving). Together, they explain that food (grass) is the main cause as wildebeests move to where food is more available, both in terms of their dietary needs (qualitative) and the measurable aspects of food distribution (quantitative).
