-CO2 + H2O + Sunlight -> Glucose + Oxygen
*Cell Respiration 
-Using oxygen to turn glucose back to carbon dioxide
-end products are carbon compounds such as methane or acetic acid.
*Food Web is a network of interconnected food chains
*Food Chain is the movement of energy and nutrients from one trophic level to the next. 
Photosynthesis -> feeding -> decomposition
*Trophic Levels
-First level - producers (plants)
-Second Level - Primary consumers (herbivores)
-Third level - Secondary consumers (carnivores)
-Fourth Level - Tertiary consumers (top carnivores)
*Ecological Pyramids 
-Tertiary consumers (humans)
-secondary consumers (perch)
Primary consumers (zooplankton)
-Producers (phytoplankton)]]> 2018-11-14 17:11:40 UTC https://padlet.com/mely1374400/m9d07mieq2d2/wish/304417410 mely1374400 https://padlet.com/mely1374400/m9d07mieq2d2/wish/304424693 Biodiversity is a variety of species,genes, ecosystem and ecosystem processes.
-Species, produce viable offspring
-species,genetic,ecosystem, and functional diversity.
*Evolution is the change in a population's genetic make up over time.
-ALL species come from earlier ancestral species.
Natural Selection occurs when a population has genetic traits that improve their ability to survive and produce offspring's with those specific traits 
-Mutation (Gene DNA, Random mistakes)
-Adaptive traits. act on existing gene.

 -Hydrogen Sulfide, released from volcanoes, swamps, bogs, and tidal flats.
-Particles of sulfate enter the atmosphere from sea spry, dust storms and forest fires. 
- Some algae product DMS
- Sulfur can convert to sulfuric acid.
-Sulfur is released to the environment when burning coal and oil. 
*Water Cycles collects, purifies and distributes the earths water.
-Rain/snow is solar energy evaporated water.
-Surface runoffs, into streams and rivers.
-Transports nutrients 
-we take large amount of fresh water, clear vegetation and increase run offs, increase flooding as draining and altering wetlands.

Nature Ecosystem Change and Ecosystem structure
Nature Ecosystem Change and Ecosystem structure
*Species
400 known species
79-97 million sharked kill per year for fins, organs,meat,hides,fear and 32% sharked species threatened with extinction.
8 to 100 million species 
1.9 million identified
pollination lets flowering plants reproduce sexually
free pest control insect - insects eat other insects
*Biological evolution is how earths life changed over time through changed in the genetic characteristics of populations
*Natural selection is the individuals with certain traits are more likely to survive and reproduce under a certain set of environmental conditions
Genetic variation
natural selection acts on individuals 
adaptation may lead to differential reproduction
Survival of the fittest
organisms do not develop traits out of need or want
reproductive capacity - species that reproduce rapidly and in large numbers are better able to adapt.
225 million years ago pangaea was 
there were at least 4 different types of movements the earth went through 
tectonic plates affect evolution and the location of life on earth
Collisions between the earth and large asteroids created new species and caused extinction
speciation when one species splits into two or more
geographic isolation happens first; physical isolation of population for a long period
species richness seems to increase productivity and stability or sustainability, and provide insurance against catastrophe
hunted started in the early 1900a
sea otters have ethics, tourism dollar and keystone species
predators may capture prey by walking, swimming, flying, pursuit and ambush, camouflage and chemical warfare

*Carbon cycles circulate through the biosphere 
-CO2 gas is a temperature controller on earth.
-Photosynthesis creates carbon in the biosphere.
-Fossil fuels also contain carbon.
-Global warming has occurred because of carbon dioxide.
*Nitrogen is recycled through the earth's systems by different types of bacteria.
-Specialized gas converts gaseous nitrogen to ammonia in nitrogen fixation.
-Nitrification is the process of bacteria, converts ammonia in the soil to nitrite and nitrate ions.
-Ammonification is a decomposer bacteria, converts detritus into ammonia and water-soluble salts. 
-In denitrification, nitrogen leaves the soil. Then two things convert NH3 and NH4 back to nitrite and nitrate, nitrogen and nitrous oxide gas are released into the atmosphere.
*Phosphorus cycle does not include the atmosphere. The major reservoir is terrestrial rock formation
-the limiting factor for plant growth is the limit on phosphate
-fertilizer for plant growth
-limits growth in producers freshwater steams and lakes due to low solubility.]]> 2018-11-14 17:30:22 UTC https://padlet.com/mely1374400/m9d07mieq2d2/wish/304429612
