Question

pop. growth: population dispersion
for each population, decide which type of population dispersion it shows.

1. lions

lions are usually found in prides - family groups of up to 40 individuals. males defend the prides territory.

1. saguaro cacti

saguaro cacti can be up to 16m tall. they are found at regular distances from each other, as there isnt enough water to support them if they are too close.

1. polar bears

polar bears are solitary animals that roam the arctic ice sheets. they arent territorial and typically avoid confrontations.

1. dandelions

dandelions use wind dispersal for their seeds - if there are sufficient conditions for germination and growth, they will grow wherever they land.
this type of population dispersion is:

Explanation:

• Lions: Since lions are in family groups (prides), this shows clumped dispersion. Clumped dispersion is when individuals are grouped together.
• Saguaro cacti: They are at regular distances as water availability limits them. This is uniform dispersion, where individuals are spaced evenly.
• Polar bears: Solitary and not territorial with no set pattern of spacing. This is random dispersion.
• Dandelions: Seeds grow where they land (no set pattern based on the description). This is random dispersion.

Answer:

1. Clumped dispersion
2. Uniform dispersion
3. Random dispersion
4. Random dispersion
