Study Notes
Limiting Factors
- Limiting factors are resources that determine the number of organisms that can live in an area.
- Limiting factors can include food, water, space, and shelter.
Ocean Acidification
- Ocean acidification occurs due to the absorption of carbon dioxide from the atmosphere into the ocean.
- Increased carbon dioxide results in a decrease in the pH of the ocean.
Nitrate Pollution
- Nitrate pollution can harm aquatic life.
- Reducing nitrate pollution can have a positive impact on the environment.
Aquatic Producers
- Aquatic producers, such as cattails, cordgrass, algae, and coontail, provide energy for other organisms in an aquatic ecosystem.
Environmental Parameters
- Measuring environmental parameters helps monitor changes in the ecosystem.
- It helps to understand whether human activities are harming the environment.
Human Impact on Biodiversity
- Human activities, like farming and urbanization, can lead to habitat destruction and biodiversity loss.
- Restoring habitats can help increase and maintain biodiversity.
Renewable Energy
- Switching from non-renewable energy sources to renewable energy sources can help reduce a carbon footprint.
- Renewable energy sources are generally expensive to implement.
Anglerfish and Carrying Capacity
- Anglerfish are deep-sea fish adapted to high pressure and cold temperatures.
- Bringing them to the surface, where temperatures are warmer, decreases their carrying capacity.
Population Growth Past Carrying Capacity
- When a population exceeds its carrying capacity, resources become scarce, and the population may decline.
- This could lead to competition for resources and potentially the extinction of the species.
Bioremediation
- Bioremediation is the use of microbes to break down pollutants in the environment.
- This can help reduce the negative impact of pollutants on ecosystems.
Energy Flow in Ecosystems
- Energy flows through ecosystems from producers to consumers.
- The amount of energy decreases as it moves up the food chain.
Scrubbers in Smokestacks
- Scrubbers are devices used to reduce sulfur emissions from factories that burn coal.
- Evaluating their effectiveness requires comparing sulfur emissions before and after scrubber installation.
Sustainable Practices
- Genetic modification and cloning can have both advantages and disadvantages in terms of sustainability.
- While they can increase productivity, they can also threaten biodiversity.
Environmental Conservation
- Monitoring the impact of substances like DDT is crucial to understand how they influence ecosystems.
- Studying the environment can help assess potential risks and protect human health.
