Energy In Biomass Flashcards

1
Q

What does a pyramid of biomass represent?

A

The mass of organisms at each stage in a food chain and are more accurate than ?Pyramids of numbers for example one bush may have many insects feeding on it but the mass of the bush is far greater than the mass of the insects

Q

Why are plants at the base of the pyramid?

A

Plants capture light energy and transfer it to chemical energy they make food which is then eaten by animals. Plants start the process of energy transfer in living organisms

Q

What is some of the biomass used as?

A

Respiration which releases energy for process which include movement so the more something moves the more energy it uses and less available for growth

16
Q

Why do materials need to be recycled in nature?

A

So the nutrients don’t run out

17
Q

What does the recycling of carbon involve?

A

Photosynthesis and respiration

18
Q

What does photosynthesis do?

A

Removes co2 from the atmosphere

19
Q

What do green plants and animals do?

A

They respire returning co2 to the atmosphere m

20
Q

What happens when humans burn or cut down trees?

A

Co2 is released

21
Q

What happens when animals eat green plants?

A

They build the carbon into their bodies

22
Q

When plants or animals die or produce waste what happens so the co2 is released back into the atmosphere?

A

Microorganism feed of them and respire giving out the co2

23
Q

What is a stable community?

A

A community that recycles all of the nutrients it takes up

24
Q

Which process takes co2 out of the atmosphere?

A

Photosynthesis

25
Q

What is organic waste?

A

Waste materials from living organisms

26
Q

Why is it good to compost garden and kitchen waste?

A

Reduce landfills
Reduce methane
Recycle minerals and nutrients

27
Q

What is the most efficient way to compost?

A

Mix waste with oxygen and moisture

28
Q

What can be added to compost to help decay?

A

Worms

29
Q

Why do councils shred waste before binning it

A

They have a larger SA so will speed up decomposition

30
Q

What is biomass?

A

The mass of living material in plants and animals
