Grade 9 Ecology

Front 1

Abiotic

Back 1

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

Front 2

Biotic

Back 2

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

Front 3

equilibrium

Back 3

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

Front 4

eutrophication

Back 4

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.

Front 5

food chain

Back 5

a simple chain of feeding relationships between three-four organisms

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

Front 6

food web

Back 6

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

Front 7

niche

Back 7

the role of an organism in a ecosystem

Front 8

overexploitation

Back 8

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

Front 9

3 types of consumers

Back 9

primary, secondary and teritary

Front 10

herbivore,carnivore, omnivore

Back 10

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

Front 11

5 terrestrial biomes in canada

Back 11

tundra,

taiga, coniferous, deciduous, grasslands

Front 12

photosynthesis reactants and products

Back 12

r: water, carbon dioxide and sunlight energy

p:oxygen and glucose(sugar)

Front 13

cellular respiration reactants and products

Back 13

r: glucose and oxygen

p: carbon dioxide and water

Front 14

trophic levels

Back 14

Trophic levels are the feeding position in a food chain

produce, primary ,secondary and tertiary consumer

Front 15

carbon cycle

Back 15

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.

Front 16

nitrogen cycle

Back 16

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.

Front 17

water cycle

Back 17

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.

Front 18

carrying capacity

Back 18

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.

Front 19

5 factors that influence population size

Back 19

competition, predation , parasitism and disease, human disturbances/clear cutting. climate extremes/natural disasters

Front 20

biosphere

Back 20

is the zone where life is created

Front 21

biome

Back 21

collection of ecosystems inhabited by certain species of life

Front 22

ecosystem

Back 22

the interacting parts of a biological community and its environment

Front 23

community

Back 23

population of all species living and interacting in an area

Front 24

population

Back 24

group of organisms of the same species living within a particular area

Front 25

individual organism

Back 25

any life form

Front 32

major factors that lead to loss of biodiversity or affect sustainability

Back 32

habitat change , overexploitation, pollution , invasive species , climate change

Front 33

soil layers/ types

Back 33

layers: top,sub,bedrock
types: Loam,clay,sand

Front 34

assessing water quality

Back 34

dissolved oxygen and BOD

Front 35

bioaccumulation

Back 35

is the gradual build up of a substance in an organisms body

Front 36

biosphere

Back 36

is the zone where life is created

Front 37

biomagnification

Back 37

is the increasing concentration of toxins in organisms up the food chain

Front 38

aquatic biomes

Back 38

fresh water and marine

Front 39

energy flow

Back 39

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
