Ecology is the study of the relationships between living and non-living things. What is all that area that contains life called?
Ecology is the study of the relationships between living and non-living things. What is all that area that contains life called? The Biosphere- Anywhere life exists. Examples = land, water, & air
Biome -similar climate & species Ex = tundra, temperate forest
Interacting biotic and abiotic factors. Where life exists –land, water, & air Biome /similar climate & species Ecosystem Interacting biotic and abiotic factors. Different populations in an area
Different populations in an area Ecosystem Interacting biotic and abiotic factors. Community Different populations in an area
Population- Group of same species in area. Community Different populations in an area Population- Group of same species in area.
Individual –one Member of a species Population- Group of same species in area. Individual –one Member of a species stop
Populations of species that interact can have a variety of relationships. Parasitism…
Parasites drain energy from other living organisms
Populations of species that interact can have a variety of relationships. parasitism predator – prey (predator eats prey)
Populations of species that interact can have a variety of relationships. parasitism predator - prey
Populations of species that interact can have a variety of relationships. parasitism predator – prey mutualistic symbiosis (2 organisms live closely together both benefit.
Populations of species that interact can have a variety of relationships. parasitism predator – prey mutualistic symbiosis (2 organisms live closely together both benefit.
Populations of species that interact can have a variety of relationships. parasitism predator – prey mutualistic symbiosis (2 organisms live closely together both benefit.) commensalism (2 organisms live closely together 1benefits the other is neither helped or harmed.)
commensalism (2 organisms live closely together 1benefits the other is parasitism predator – prey mutualistic symbiosis (2 organisms live closely together both benefit.) commensalism (2 organisms live closely together 1benefits the other is neither helped or harmed.) monarch = poisonous viceroy = nonpoisonous
How did the viceroy evolve to use this type of camouflage? viceroy = nonpoisonous monarch = poisonous
Ecology is studied in a variety of ways. Compare/Contrast Table Section 3-1 Ecological Methods Observation Experiment Model Building Sites Field site Experimental plots, field sites, laboratory Many sites for data collecting Measuring Tools Tapes, compass, Global Positioning System, thermometer, sensors Aerial views, Global Positioning System, weather balloons Magnifying Tools Binoculars, microscope, telescope Satellite images Written Record Notes, automated data storage Automated data storage Chemical Testing Test kits Large database, multiple sensors Computer/ Calculators Mathematical analysis and graphics, statistics and graphics, statistics, simulations Go to Section:
What is the ultimate source of energy for most life on Earth?
What is this ? Decomposers bacteria & fungus bacteria & fungus
Food Chains show how energy moves through the ecosystem. What are the trophic levels in a food chain. and what are some terms that describe them.
heterotroph autotroph omnivore carnivore herbivore decomposer Decomposers bacteria & fungus bacteria & fungus
Food Chains show how energy moves through the ecosystem. Producer Make 100%of food 100lbs. Primary Consumer 10% 10lbs. Secondary Consumer 1% 1lbs. carnivore Heterotroph Decomposer .1% .1lbs. Heterotroph heat heat heat heat 10% 10% 10% green plant herbivore decomposer Heterotroph Autotroph Eats something else
Compare & contrast food chain & food web.
What can be shown with pyramids? Ecological Pyramids Section 3-2 Energy Pyramid Shows the relative amount of energy available at each trophic level. Organisms use about 10 percent of this energy for life processes. The rest is lost as heat. Pyramid of Numbers Shows the relative number of individual organisms at each trophic level. Biomass Pyramid Represents the amount of living organic matter at each trophic level. Typically, the greatest biomass is at the base of the pyramid. Go to Section:
Matter is not created or destroyed it is cycled through living and non-living parts of the environment. List 3 examples of Matter that cycles. (Hint- think elements.)
Water Cycle
Carbon Cycle
Phosphate Cycle
carbon + water + nitrogen + phosphate =
carbon + water + nitrogen + phosphate = C HO N P CHO CHON CHONP
carbon + water + nitrogen + phosphate = C HO N P CHO - carbohydrates and lipids CHON - proteins CHONP – nucleic acids CHONPS- some of protein’s amino acids require sulfur
Sulfur Cycle Some amino acids also require sulfur
Limiting factors can prevent or limit growth. Why was your bean not growing when you first got it? (what was the limiting factor)
nitrogen deficiency normal growth Why does limiting nitrogen cause so many problems?
Nutrients provide material for growth and living. Anytime there is not enough of a required nutrient growth and life is limited.
The more productive the ecosystem the more standing biomass. What is the most productive ecosystems?
Pollution can be chemicals, nutrients, conditions, or structures that are harmful. Its amazing just how large a problem this can be!
Eutrophication is the gradual filling in of bodies of water through the build up of sediment. How would an algae bloom affect this?
How can eutrophication be sped up by human activities?
If there are lots of plants why would other organisms die?

Some things like mercury are bioaccumulative. It becomes more concentrated as you go up the food chain. How can you reduce this problem?
