Animals And Ecosystems

Question 1

Population?

Answer 1

A group of a particular organism

Question 2

Community?

Answer 2

Different populations interacting with each other

Question 3

Habitat?

Answer 3

Where the organisms live

Question 4

Interdependence?

Answer 4

Populations replying on eachother

Question 5

Abiotic factors?

Answer 5

Non-living conditions which can influence where plants and animals live
Light intensity, temp,water,wind

Question 6

Why animals can’t get all the energy from an organism they eat?

Answer 6

Energy released through movement, excretion of waste, regulating body temperature. Also some parts of animals are inedible

Question 7

Biotic factors?

Answer 7

Living conditions that affect where a plant or animal lives

Food,predators,pathogens

Question 8

Parasitism?

Answer 8

An organism benefits by feeding off of a host organism. Lives in or on the host and host usually survives

Question 9

Mutualism?

Answer 9

Organisms living together that both benefit. Eg. Bee pollinates flower (producing fertilised eggs) and the bee has food

Question 10

Eutrophication?

Answer 10

Addition of more nutrients into an ecosystem than it normally has, eg. Fertiliser

Question 11

Potable?

Answer 11

Drinkable

Question 12

Water cycle process?

Answer 12

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

Question 13

What makes a drink potable?

Answer 13

Sterilised with chemicals and dirt filtered out

Question 14

Desalination?

Answer 14

Collecting water from the sea

Question 15

Directions arrow means?

Answer 15

Eaten by

Question 16

Humans are?

Answer 16

Top consumers

Question 17

How carbon dioxide gets in the air?

Answer 17

Burning fossil fuels, respiration, decay

Question 18

Host

Answer 18

Organism where a parasite lives

Question 19

Parasite

Answer 19

Am organism that lives off a host and cause the host harm

Question 20

Ways carbon is released into the air?

Answer 20

Respiration, fossil fuels(combustion)

Question 21

How nitrogen is in the air?

Answer 21

Death and excretion, proteins and urea in soil, nitrates in soil are broken down by bacteria in soil into the air

Question 22

How can animal species be conserved?

Answer 22

Building nesting platforms for animals to live. Killing their predators

Question 23

How can reforestation affect biodiversity?

Answer 23

Increases range of habitat and increase number of species living in the area

Question 24

How can conservation protect biodiversity?

Answer 24

When animals are assisted in survival, their numbers increase and therefore other animals’ numbers increase due to mutualism and interdependence

Question 25

Indigenous and non indigenous?

Answer 25

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

Question 26

Water cycle?

Answer 26

Ground water moves through soil and rock, rivers flow into lakes and eventually water returns to ocean
Evaporation
Condensation
Precipitation

Question 27

Eutrophication cycle?

Answer 27

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
