○ Examples:
18. Population Ecology and Growth:
a. Environmental resistance factors
i. Conditions and resources that affect the ecology and growth of
populations/communities are:
● Density dependent factors: affect a population as the population
increases (increases density)
● Density independent factors: natural or human-caused
environmental calamities. These are not based on the population
size.
b. Exponential growth:
i. A population’s size increases rapidly due to unrestricted growth
ii. “J curve”
iii. This growth is eventually limited due a limiting factor
c. Logistic growth
i. Population growth that has stabilized because of resource limitations
ii. As density increases, a population reaches the carrying capacity of its
environment, and limited resources put a ceiling on growth

Answer 1

Here are two actions you can take for $10.00 or less to reduce your ecological footprint:

1. Reusable Water Bottle: Purchase a reusable water bottle (around $10 or less). By using a reusable bottle instead of single-use plastic bottles, you reduce plastic waste and decrease the demand for natural resources needed to manufacture those bottles. This small change also promotes hydration while minimizing unnecessary consumption.

2. LED Light Bulb: Buy an energy-efficient LED light bulb (usually priced around $10 or less). Replacing traditional incandescent bulbs with LED bulbs reduces electricity consumption significantly, as LEDs use at least 75% less energy and last much longer. This can lower your electricity bill while contributing to a reduction in greenhouse gas emissions.

Related to Population Ecology and Growth:

• Density Dependent Factors: These factors include things like limited food supply, disease, and competition for resources. As population density increases, these factors become more pronounced, leading to a natural regulation of population growth.

• Density Independent Factors: Examples are natural disasters like hurricanes, droughts, and human activities like pollution or habitat destruction. These factors can dramatically affect populations regardless of their size or density.

• Exponential Growth (J Curve): In ideal conditions without limiting factors, a population can grow rapidly in size. This type of growth is often unsustainable in the long term due to limited resources.

• Logistic Growth: This occurs when a population reaches its carrying capacity—meaning the environmental resources can only support a certain number of individuals. Growth slows as resources become scarce, resulting in a more stable population size.
