1.5 and 1.2 Flashcards
One characteristic of Pollution?
Pollution is highly diverse phenomenon of human disturbance in ecosystems
How can Pollution Management Strategies be used?
pollution management Strategies
can be applied at different levels
What is Pollution?
Pollution is the addition of substance or an agent to un environment through human activity, at a rate greater than which it can be rendered harmless by the environment
What effect does pollution have?
Has an appreciable effect on
organisms in the environment
What Are Pollutants?
Pollutants may be in the form of Organic or inorganic Substances, light,
Sound, thermal energy, biological agents or invasive species, and may derive from a wide range of human activities including.
combustion of fossil fuels
How Can Pollutants be Presented?
Pollutants may be non-point or Point source, persistent or biodegradable acut or chronic.
Pollutants may be primary (active emission or secondary arising from primary pollutants undergoing physical/ chemical
change
DDT
exemplifies conflict between the L utility of a “pollutant” and its effect on the environment.
Process Of Pollution
human activity producing pollutant
Release pollutant into eviviorment
level of pollution managment
controlling reales of pollutant
- Activity /production not stopped
- Strategies applied at the level of
-regulating or preventing release
-regulating standard of emission
Levels of Pollution Management
Level of pollution management
- Altering human activity
- Change human activity by promoting alternative tech, lifestyles and values
- government
-campaigns
-legislation
- education
- community groups
Impact of pollutant on ecosystem
Clean-up restoration of damaged Systems
- both leveles of manegment failed
- Strategies introduce recover
damaged ecosystems
- extracting removing pollutant
- replanting / restocking
depleted populations
Species
Species interacts with its abiotic an biotic environments, and its niche is described by these interactions
Population
- populations change and respond to interactions with the environment
Systems
Any system has a carrying Capacity for a given Species
Species #2
Species is a group of organisms that Share com on characteristics and that interbreed to produce fertile offspring.
What are Habitats
A habitat is the environment in which a species normally lives
What’s a Niche
A niche describes
the particular set
or abiotic and biotic conditions and resources to which and organism
or population responds.
Fundamental Niche
The fundamental niche describes the full range of conditions and resources in which species could Survive and reproduce.
realized niche
The realized niche describes the actual conditions and resources
In which a species exists due to biotic interactions.
non- living an physical factors
The non- living an physical factors that influence the organisms and ecosystem - such as temp, Sunlight, pH, Salinity, precipitation and termed abiotic factors.
Interactions Between Organisms
The interactions between the organisms such as predation, herbivore, Paratism, mutualism, disease. and competition are biotic factors
Some organisms, habitats change over time due to migration
Interactions Between Organisms #2
in terms of the influence each species has on the population dynamics of others and upon the carrying capacity of the otters environment
Ecosystems
community and physical
environment with which interacts Community + abiotic factors
Biomes
Biomes
ecosystems sharing similar climatic Conditions that can be grouped.
aquatic, forest, grass land, desert.
limiting factors
Productivity Biodiversity
