Q

Interactions

A

Living organisms interact with each other and their abiotic environment

17
Q

As rainfall increases

A

Desert to grassland to forest

18
Q

As temperature increases

A

Cool to temperate to tropical

19
Q

Affected by

A

Temperature, rainfall, latitude and altitude

20
Q

Producers

A

Plants, algae, produce energy from the Sun, autotrophs

Deep ocean bacteria, chemosynthesis

21
Q

Consumers

A

Herbivorous are primary, carnivorous are secondary, tertiary, etc

22
Q

Decomposers

A

Break down living things to leave no waste

23
Q

Food web vs food chain

A

Food chain is single line while food web branches out

24
Q

Energy

A

Energy is lost by the animal living and therefore less energy is given to the next level consumer

25
Solar insolation
Amount of sunlight received, more at equator than poles. Ecosystems rely on large amounts of solar insolation
26
Common types of terrestrial biomes
- Desert - Tropical savanna - Coniferous forest - Polar - Alpine
27
GPP
Gross primary production | Total energy produced by producers
28
NPP
Net primary production | Energy released into the ecosystem by the producers
29
Highest NPP
Swamps, tropical rainforests and estuaries
30
98%
Of Terrestrial, vertebrate biomass are human, livestock or pets (estimated)
31
Staple food
Eaten regularly by a community, main part of diet | Egs: rice, wheat, yam, corn, potato
32
Grains and Grasses
Annual, main food for most people
33
Traditional food
Gaining popularity in developed countries
34
Best biome
Temperate grassland due to rich soil and temperature
35
Humans alter biomes
Vegetation and habitat clearance, source water supplies, terracing
