funniest immage ever

8th gr. IB program There will be a meeting for any 8th grade students interested in participating in the International Baccalaureate Program at Harriton High School in the Cafeteria during LEARN on Wednesday. You may sign up under the IB Course with Mr. Hunter at the LEARN site.

Oh wow, idk how that got there.

You may only post if you are funny

Lol, that's not even a functioning link.

It should describe your research interests, your professional goals, your background and experience, and your hopes for what you'll get out of participating in the REU program

ecology- how organisms interact with each other and their environment
environment- living and nonliving components
abiotic- non-living components or physical factors as soil, rainfall, sunlight and temperatures
biotic- living components or other organisms
individual- individual organisms
population- organisms of the same species in the same area
community- several populations in the same area
ecosystem- community plus abiotic factors
biosphere- all ecosystems on Earth
homeostasis- delicate balance
survivorship- the percentage of a population remaining over time
Type 1 survivorship- most individuals live out their full lifespan and die of old age
Type 2 survivorship- individuals die at a constant rate
Type 3 survivorship- most individuals die young in life
neutral interactions- two species do not interact
mutualism- both interact
commensalism- one benefits, other neutral
parasitism- one benefits, other is harmed but not killed
predation- one benefits, other is killed
ecological pyramid- a graph representing trophic levels within an ecosystem. the primary producer level is at the base of the pyramid with consumer levels above
numbers pyramid- compares the number of individuals in each trophic level
biomass pyramid- compares the total dry weight of the organisms in each trophic level
energy pyramid- compares the total amount of energy available in each trophic level this energy is usually measured in kilocalories
point source pollution- pollution with a specific source
nonpoint pollution- pollution comes from many sources
organic pollution- decomposition of living organisms and their bi-products
inorganic pollution- dissolved and suspended solids as silts, salts, and minerals
toxic pollution- heavy metals and other chemical compounds that are lethal to organisms
thermal pollution- waste heat from industrial and power generation processes
radiation pollution- radioactive materials
deforestation- the permanent destruction of indigenous forests and woodland
non-renewable energy- fossil fuels
renewable resources- sun, wind, heat, waves
eutrophication- the enrichment of an ecosystem with chemical nutrients, typically compounds containing nitrogen, phosphorus or both
Biological treatment- process in which wastewater is treated with aerobic bacteria to remove or reduce the organic contaminants such as human and animal excreta, ammonia, nitrates, and and plant tissue
species- a group of similar organisms that can mate with each other and produce offspring that can also mate with each other
microbes- a microorganism, especially a pathogenic bacterium
biome- a complex biotic community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region, especially such a community that has developed a climax
limiting factor principle- an environmental factor that tends to limit population size
aerobic respiration- oxygen is taken in and carbon dioxide and water are produced; also, the use of oxygen in the breakdown of food to create energy
