Abiotic

non-living. ie. sunlight, water, soil, oxygen, temperature

Biotic

living. anima;s, insects, growth rate, bacteria

equilibrium

Chemical equilibrium is the balance between the amount of products being produced, and the amount of products reacting back to the reactants.

eutrophication
when fertilizer and manure from the land gets washed into nearby bodies of water by rain. the nutrients and minerals of the stuff is absorbed and utilized by aquatic plants in the water. the plants then slowly consume almost all the oxygen in the water bodies. that creates a top layer on the water which blocks sunlight from reaching the bottom so plants cannot photosynthesize. therefore because of that the rest of the biotic factors in the water die because lack of nutrients and oxygen.

food chain

a simple chain of feeding relationships between three-four organisms



is the way energy goes from one living thing to another through food

food web

a network of food chains/feeding relationships by which energy and nutrients are passed on from one species of living organisms to another

niche

the role of an organism in a ecosystem

overexploitation

means to harvest,extract or utilize water,gas,oil natural resources. when that stuff carries out a rate so great that leads to destruction/damage its called overexploitation

3 types of consumers

primary, secondary and teritary

herbivore,carnivore, omnivore

herbivore is an organism that only eats plants


omnivore is an organism that eats both plants and animals


carnivore is an organism that eats only meat//animals

5 terrestrial biomes in canada

tundra,


taiga, coniferous, deciduous, grasslands

photosynthesis reactants and products

r: water, carbon dioxide and sunlight energy


p:oxygen and glucose(sugar)

cellular respiration reactants and products

r: glucose and oxygen


p: carbon dioxide and water

trophic levels

Trophic levels are the feeding position in a food chain



produce, primary ,secondary and tertiary consumer

carbon cycle

Carbon is released into the air, absorbed by plants. Plants photosynthesize. Carbon dioxide + Water = Oxygen and Sugars. Plants release this oxygen. Animals breathe in the oxygen and breathe out carbon dioxide and the cycle continues.

nitrogen cycle

Nitrogen from the atmosphere is fixed through nitrogen fixation or nitrification. Nitrogen fixation fixes the nitrogen and plants are able to absorb it, then other species eat the plants and gets contained in their bodies. Nitrification is when the decaying organic matter releases nitrate and nitrites that turns into ammonium, which seeps back into the soil. The third way nitrogen gets cycled is denitrification - a chemical process that converts nitrates back into molecular nitrogen.

water cycle
Earth's water evaporation from the surface, condenses into clouds and precipitation to runoff, soil or water accumulation to the re-evaporation, the cycle of the cycle.

carrying capacity

The largest population size of a given species that an area can support without reducing its ability to support the same species in the future. Population size is stable when death: birth ratio equal.

5 factors that influence population size
competition, predation , parasitism and disease, human disturbances/clear cutting. climate extremes/natural disasters
biosphere
is the zone where life is created
biome
collection of ecosystems inhabited by certain species of life
ecosystem
the interacting parts of a biological community and its environment
community
population of all species living and interacting in an area
population
group of organisms of the same species living within a particular area
individual organism
any life form
biosphere
is the zone where life is created
biome
collection of ecosystems inhabited by certain species of life
ecosystem
the interacting parts of a biological community and its environment
community
population of all species living and interacting in an area
population
group of organisms of the same species living within a particular area
individual organism
any life form
major factors that lead to loss of biodiversity or affect sustainability
habitat change , overexploitation, pollution , invasive species , climate change
soil layers/ types
layers: top,sub,bedrock
types: Loam,clay,sand
assessing water quality
dissolved oxygen and BOD
bioaccumulation
is the gradual build up of a substance in an organisms body
biosphere
is the zone where life is created
biomagnification
is the increasing concentration of toxins in organisms up the food chain
aquatic biomes
fresh water and marine
energy flow
ecology - ecosystem that spreads out into biotic and abiotic factors. the biotic factors consist of decomposers,detritus ores consumers and producers. consumers consist of primary and secondary consumers. both have omnivore but primary has herbivore and secondary had carnivore
