Animals And Ecosystems Flashcards
Population?
A group of a particular organism
Community?
Different populations interacting with each other
Habitat?
Where the organisms live
Interdependence?
Populations replying on eachother
Abiotic factors?
Non-living conditions which can influence where plants and animals live
Light intensity, temp,water,wind
Why animals can’t get all the energy from an organism they eat?
Energy released through movement, excretion of waste, regulating body temperature. Also some parts of animals are inedible
Biotic factors?
Living conditions that affect where a plant or animal lives
Food,predators,pathogens
Parasitism?
An organism benefits by feeding off of a host organism. Lives in or on the host and host usually survives
Mutualism?
Organisms living together that both benefit. Eg. Bee pollinates flower (producing fertilised eggs) and the bee has food
Eutrophication?
Addition of more nutrients into an ecosystem than it normally has, eg. Fertiliser
Potable?
Drinkable
Water cycle process?
Ground water moves through soil and rock into water supplies
Rivers flow into lakes and eventually goes to the ocean
Water evaporates
Cool air condenses vapour into clouds
As water droplets get too large and heavy they fall as rain/snow
What makes a drink potable?
Sterilised with chemicals and dirt filtered out
Desalination?
Collecting water from the sea
Directions arrow means?
Eaten by
Humans are?
Top consumers
How carbon dioxide gets in the air?
Burning fossil fuels, respiration, decay
Host
Organism where a parasite lives
Parasite
Am organism that lives off a host and cause the host harm
Ways carbon is released into the air?
Respiration, fossil fuels(combustion)
How nitrogen is in the air?
Death and excretion, proteins and urea in soil, nitrates in soil are broken down by bacteria in soil into the air
How can animal species be conserved?
Building nesting platforms for animals to live. Killing their predators
How can reforestation affect biodiversity?
Increases range of habitat and increase number of species living in the area
How can conservation protect biodiversity?
When animals are assisted in survival, their numbers increase and therefore other animals’ numbers increase due to mutualism and interdependence
Indigenous and non indigenous?
Indigenous means the animal originated from that area and naturally occurs there. Non indigenous means the organism doesn’t naturally live there but is living outside its native distributional range
Water cycle?
Ground water moves through soil and rock, rivers flow into lakes and eventually water returns to ocean
Evaporation
Condensation
Precipitation
Eutrophication cycle?
Addition of more nutrients, eg fertiliser
Rain washer fertiliser off and nitrates and phosphates dissolve into water and into river stream
High nitrates and phosphates encourages algae and plants to grow quick
Surface plans block sunlight and water plants stop photosynthesis growth and producing oxygen. Oxygen levels decrease and aquatic animals die
