CARRYING CAPACITY of ECOSYSTEMS

Population size/Size of area = Population density (avg # species per unit area)

Uniform, Random, Clumped -

Exponential Growth -

Immigration -INTO an area
Emigration - EXIT an area

​Determined by abiotic and biotic factors

Multiple Choice

What happens to fertilizer we put on our lawns

• It kills grass

• It runs off land into bodies of water causing pollution

• It evaporates

• It only has positive impacts

Multiple Select

How can we reduce greenhouse gas emissions?

• Buy large SVUs that use gasoline

• use energy efficient appliances

• use clean energy

• Reduce public transportation

Multiple Select

Renewable energy

• takes millions of years to produce

• produced naturally

• extracted through mining

• reduce pollution

CLIMATE CHANGE
Cause Increase in CO2 - Burning Fossil Fuels for electricity, forest fires, volcanic eruptions,
decomposition of organic matter
Increased CO2 leads to increased temperature
Increased CO2 falls into ocean increasing acidity
Carbon sequestration and photosynthesis remove CO2
