Question

For each of the organisms listed below, state the type of population distribution and population density of their habitat. Give a reason for each answer. Organism Distribution Density Reason

a) Tigers: Clumped, High density, because they live in groups for hunting.
b) Bison: Random, Moderate density, because they roam freely across the plains.
c) Ants: Uniform, High density, because they maintain individual spacing within colonies.
d) Dandelions: Random, Low density, because they disperse seeds widely.
e) Apple trees in an orchard: Clumped, High density, because they are intentionally planted close together.

Answer 1

Organisms exhibit different patterns of population distribution and density due to various ecological and behavioral factors. Tigers are clumped but vary in density, bison are clumped in herds with moderate to high density, ants are clumped with high density, dandelions are randomly distributed with variable density, and apple trees in orchards have a uniform distribution with high density.

Step-by-step explanation:

For each organism, population distribution and population density are associated characteristics with specific reasons. Here's a brief correction and expansion on the given answers:

• Tigers: Typically, tigers have a clumped distribution as they can be found in areas where there is a rich presence of prey, though they are solitary animals. Their density is varied, with some areas experiencing low density due to large territory requirements and others higher density where prey is abundant.
• Bison: Bison tend to show a clumped distribution, moving in herds across grasslands which provides safety and facilitates foraging. Their density can be moderate to high depending on the abundance of grasses and the size of the herd.
• Ants: They have a clumped distribution around their nest with a high density because they live in large colonies and work together to gather resources and protect their nest.
• Dandelions: These plants exhibit a random distribution because their seeds are dispersed by the wind to various locations. They can have a variable density, often low, as it depends on where their seeds land and take root.
• Apple trees in an orchard: They are planted by farmers and therefore have a uniform distribution with a high density, as they are intentionally spaced in organized rows for ease of maintenance and harvesting.

Population density refers to the number of individuals per unit area or volume, while population distribution refers to the pattern in which the individuals are spread out over their environment. Factors like resource availability, social behavior, and reproductive strategies influence these two characteristics.
