Functional

Answer 14

Desert animals conserve water by producing very little swaet and small amounts of concentrated urine.

Question 15

Bears Functionality

Answer 15

Hibernate during the winter lower their metabolism which conserves their energy.

Question 16

Food chains

Answer 16

Food chains always start with an producer eg dandelions.

Question 17

Producers

Answer 17

Producers are usually green plants or algae

Question 18

Energy

Answer 18

Energy is transferred through living organisms in an ecosystem when organisms eat other organisms.

Question 19

Producers 2

Answer 19

Producers make (produce) their own food using energy from the sun.

Question 20

Food Chain 2

Answer 20

Producers are eaten by primary consumers. Primary consumers are then eaten by secondary consumers and secondary consumers are eaten by tertiary consumers.
Eg
Producer 5000 dandelions feed 100 rabbits primary consumer which feed 1 fox secondary consumer.

Question 21

Carbon cycle

Answer 21

The constant cycling of carbon is called the carbon cycle.

Question 22

Environmental change

Answer 22

The distribution of bird species in Germany changing as rise in temperature.

Question 23

Water Cycle

Answer 23

The water cycle means the endless recycling of water.

Question 24

Decay

Answer 24

Microorganisms break down plant and animal waste to get energy.

Question 25

Temperature-Decay

Answer 25

The temperature causes faster rate of decay.

Question 26

Oxygen-Decay

Answer 26

Oxygen availability is often a way in which microorganisms die as a result of decay.

Question 27

Water-Decay

Answer 27

Water availability leads to decay to animals that are to weak to fight for water.

Question 28

Number of decay organisms

Answer 28

The more microorganisms the faster decomposition happens.

Question 29

Biogas

Answer 29

Methane is an biogas which can be burned as fuel.

Question 30

Biogas-Fermenter

Answer 30

Biogas is made in a simple fermentor called a digester or generator.

Question 34

How do green plants remove carbon dioxide

Answer 34

Photosynthesis

Question 35

Combustion

Answer 35

Burning

Question 36

Trees

Answer 36

Trees only give out carbon dioxide when they die

Question 37

Photosynthesis

Answer 37

Carbon dioxide+water=glucose+oxygen

Question 38

Respiriation

Answer 38

Glucose+oxygen=carbon dioxide+water

Question 39

Combustion

Answer 39
