Answer:
1. density-dependent factors - competition, predation, parasitism, and disease.
density-independent factors- natural disasters, seasonal cycles, unusual weather, and human activity
2.
As populations increase in size, completion increase as well. For example more people more food demands. as populations become larger and more and more crowded people compete for food, water, sunlight, spaces to live and so on.
3.
Example:
A prolonged drought, with its associated crop loss could cause deaths, financial hardship, and emigration to other areas.
4.
both are under pressure to change in ways that reduce competition, may evolve to occupy different niches
5.
parasites take nourishment from a host - weakening it / killing it
6.
favorable conditions: agriculture, medicine, industry, sanitation
7.
It equal age distribution = very slow, steady growth
large % of children and teenagers = very rapid growth
8.
the recourse may be a part of a organism's niche/habitat (ex. panda and bamboo)
9.
Density (d) depends upon the mass (m) and volume (v) of a substance. The mass depends upon the amount of matter in a substance, whereas volume is the amount of space that a substance takes up.
