The four spheres of Earth and what they encompas?
What is the biosphere (all living things), Hydrosphere (all water), atmosphere (all gases), Geosphere (all terrain above and below Earth's crust)
What is the process in which autotrophs with no sunlight use chemical reactions to make energy for themselves
How does matter flow between trophic level
What does each growth rate mean? =0, >0, <0
No growth, Positive Growth, Negative Growth
What is a keystone species?
What is a species that maintains an entire food web and without the foodweb collapses
Describe and El Niño or ENSO event?
What is an event where currents in the water travel slower or different to their normal patterns causing climate issues like warmer water leading to less nutrients for fish
Name 2 primary producers and why they are called that
ANY PLANTS -> they convert sunlight into energy for other plants to use -> autotrophs
What four processes cycle matter?
Respiration (Breathing), Photosynthesis, Decomposition, and Human made ammonia
What is carrying capacity?
The max population an ecosystem can sustain
List all three types of symbiosis
What is Mutualism, Commenalsim, Parasitism
What is the effect where gasses on Earth trap heat
How much energy is transfered between trophic levels?
What is 10%
When certain nutrients are lacking, the food web is thrown off balance and whole species can dwindle.
Give 3 examples of density dependent factors
What is Sickness, Competition, Resources, Waste
Describe Mutualism, Parasitism, and Communalism with examples
Mutualism (+,+) bees and flowers, Communalism (+,0) barnacles and whale, Parasitsm (+,-) Leeches and humans
List 4 abiotic factors in Louisiana's swamps
Sunlight, Water, Wind, Temperature, CO2
How does Nitrogen enter the biological cycle?
What is it is turned into NH3 from N2 by bacteria in the soil. That is Nitrogen Fixation and the NH3 is usable by biological life.
What are the four major macromolecules
Lipids, Proteins, Carbohydrates, Nucleic acids
Give 4 examples of density independtent factors
Why can no two species have the same niche?
What is the competetion for resources will be too great leading one species to die or adapt
Difference between Weather and Climate
Weather is the short term conditions of the atmosphere like storms or heatwaves while climate is the long term expected weather cycles and temperatures of an area
List 4/6 Consumers and what they eat
Carnivores (MEAT), Herbivore (PLANTS), Omnivore (MEAT AND PLANTS), Decomposer (BREAKS DOWN DEAD ORGANISM INTO DETRITUS), Detritivore (DETRITUS), Scavenger (EATS DEAD THINGS)
List four proccesses of the Nitrogen cycle
What is denitrification (bacteria turns nitorgen to NH3), assimilation (How organsism incorporate Nitrogen into tissue), Haber process (How humans made ammonia from N2), Nitrification (how ammonia is made into nitrates for plants), Nitrogen Fixaction (How nitogen is made into usavble forms for biological life)
What are some reasons for population growth in the 20th century?
Post war baby boom, increase medicinal practices, eliminations of one baby per family rule
What is the difference between Secondary and Primary Succession
Primary succession is the growth of an ecosystem from no soil, roots, seeds, ect... whle secondary succesion is the rebuilding of an abonded community that HAS soil, seeds, roots, ect. (Longer v Shorter
