What is the difference between R and K selective


What is the difference between R and K selective? Provide an example of a K specialist species and an R specialist species (find examples outside the textbook). What kind of environment would favor each and why?

2.2 According to our textbook, a biotic factor is a living element found within an ecosystem, while an abiotic factor is a nonliving element found within an ecosystem. Choose a biome and ecosystem and provide an example of a biotic and abiotic factor found within your biome/ecosystem. Explain the importance of these factors to your specific biome/ecosystem.

3.1 The growth rate equation is (birth rate + immigration)-(death rate + emigration). Provide at least two factors that affect the population size based off the equation above, and explain how these factors impact the size of the population.

3.2 Identify any unusual environmental problems (for example: heavy metals due to mining, water pollution due to farming or industry) in your neighborhood and research possible health effects of potential environmental hazards in the area. Who is at risk, what is the environmental hazard, where does this hazard come from and what health problems caused by the pollutant? Before you get started, review the terminology.


Environmental Hazard: Something (chemical, physical or microbiological) with the potential to cause harm; however, it does not always put you at risk.

Risk: The combination of the probability or frequency, of occurrence of the identified hazard and the magnitude of the consequences of the occurrence.

Risk assessment: Risk assessment is the process of estimating the potential impact of a chemical, physical, or microbiological hazard on a specified human population or ecological system under a specific set of conditions and for a certain time frame.

4.1 Farmers use fertilizers to improve crop growth which can impact the environment though agricultural runoff. What is agricultural runoff? Provide two examples of how farmers can prevent it. 

4.2 Superweeds are plants having a high resistance to different herbicides. How do superweeds grow? Do GMOs influence the growth of superweeds? Why or why not?

5.1 Describe a natural protected area where you live (city or state).

Where is this park and what makes people want to visit it?

Have you been there or do you plan to in the future?

What are some efforts made to protect the area (natural features, animals, plants, etc.)?

Provide an example of a place that is or has undergone primary succession.

Provide an example of a place that is in or has undergone secondary succession.

6.1 Select a national monument. How has it been affected by weathering? Be sure to specify the type of weathering it is exposed to.

6.2 Select a type of renewable energy. Compare it to fossil fuels by explaining two pros and two cons for its implementation on a large scale. Maintain an environmental focus (do not just give economic reasons).

7.1 Provide one example for point source pollution and one example for non-point source pollution. Identify one type of water pollutant and what are the effects this pollutant has on the environment?

7.2 What are some examples of water use and describe some examples of domestic water conservation? Define the Clean Water Act and Safe Drinking Water Act (make sure to include in-text citations and references).


Each question needs to be answered by itself and have a cite in the answer and have 200 words in the answer.
