Rachael's Biology Ecology Flash Cards

?
Habitat
Physical place occupied by an organism
1 of 33
Population
All organisms of one species in an area at one time
2 of 33
Community
All organisms in an area at one time
3 of 33
Eco system
Interaction of a community of living organisms with the non living parts of the environment
4 of 33
Abiotic
Non living
5 of 33
Biotic
Living
6 of 33
Give me some abiotic factors
Moisture level, light intensity, temperature, carbon dioxide level, wind intensity, oxygen level, soil pH
7 of 33
Give me some biotic factors
Predators, competition, pathogens, availability of food
8 of 33
Interdependence
Each specie relying upon each other for things such as food
9 of 33
Stable communities
Have a balance in population size and it stays roughly constant
10 of 33
Adaptations
Allow organisms to survive, they can be structural, behavioural or mechanical
11 of 33
Give me some structural adaptations
Shape, colour
12 of 33
Give me some behavioural adaptations
Migration
13 of 33
Give me some mechanical adaptations
Animals lower there metabolism when hibernating
14 of 33
What is the order of a food chain
Producer, primary consumer, secondary consumer, tertiary consumer
15 of 33
Tropic levels
Tropic level 1 contains producer, level 2 contains primary consumer and so on
16 of 33
Biomass
Amount of energy stored in a plant/animal
17 of 33
Pyramids of biomass
Show the relative mass of each trophic level
18 of 33
Biomass transfer
Biomass is lost between each trophic level because the energy is used for things such as movement, so the next level will get less
19 of 33
Calculate efficiency of biomass transfer
Efficiency = biomass transferrred to next level / biomass available at previous level x100
20 of 33
Quadrats
Randomly select coordinates in sample area to calculate organism population
21 of 33
Transects
To study the distribution of organisms along a line
22 of 33
Water cycle
Evaporation, condensation, transpiration, precipitation
23 of 33
Carbon cycle
Burning, photosynthesis, products of plants/animals, respiration, decay
24 of 33
Factors affecting the rate of decay
Temperature, oxygen availability, water availability, no. of decay organisms
25 of 33
Biogass
Made by anaerobic decay (no oxygen), the methane is used as a fuel immediately as it cannot be stored. Biogass generators can be batch or continuous
26 of 33
Biodiversity
Variety of different species of organisms living in an area
27 of 33
Global warming
Carbon dioxide and methane trap energy from the sun
28 of 33
Deforestation
Cutting down trees for space, farming, the wood. Carbon is released, and there's less photosynthesis
29 of 33
Peat bogs
Peat is partly rotted plant matter build up in areas of land which are acidic and waterlogged. When peat is cut up, carbon is released
30 of 33
Food security
Having enough food to fead the growing, demanding population
31 of 33
How to make food production more efficient
Animals given small pens, less exercise, more feed. Eating higher protein food. Genetic modification
32 of 33
What's been done about over fishing
Fishing qoutars, small net sizes
