Ecology Flashcards
What are ecosystems?
Communities interacting with non living things
What is interdependence?
Species being dependent on other species
What are some abiotic and biotic factors?
Abiotic (non living): Moisture level Light intensity Temperature Carbon dioxide level Wind intensity Oxygen level Soil pH
Biotic: Predators Food New pathogens Competition
What do animals compete for?
Animals:
Food
Territory
Mating
Plants:
Light
Space
Water and minerals
What’s the order of food chains?
Producer
Primary Consumer
Secondary Consumer
Tertiary Consumers
What’s the carbon dioxide cycle?
Animals feed on plants containing CO2.
Animals eventually die and fossilise
They are turn to cool, oil and gas
CO2 goes in the air and plants absorb it
How do humans decrease biodiversity?
Buildings Quarrying Landfill Peat bogs Deforestation
What are the different types of pollution?
Landfill
Smoke and acid rain
Pesticides in water
What are the effects of biodiversity?
Loss of habitats
Changes in distribution
Changes in migration
Reduced biodiversity
