Roles of Living Things  All organisms need energy to live.  In ecosystem, energy moves in ONE direction: Sun Organisms  Energy from sun enters ecosystem.

What’s wrong with this food chain?

Arrows pointing wrong way

How do you work out biomass?

Number of organisms x average (dry) mass

List 2 ways energy is lost as you move up a food chain

Some parts don’t get eaten Some lost as faeces Some used in respiration (movement, keeping warm etc)

Why can farmers make more money by keeping battery hens in cages than they can from free range?

Less energy is lost in moving and keeping warm so farmers can feed them less

Name 2 biofuels

Biogas (methane) Bioethanol Wood

How do you make biogas?

Fermentation By bacteria In a digester

Why do farmers use pesticides?

So pests don’t eat crops (Less of the crop’s energy is lost to pests is a better answer)

What is biological control?

A natural predator eats the pest

What are the advantages of biological control?

No toxic chemical Useful insects not harmed Top predators not poisoned

What 3 conditions do decomposers need to grow?

Oxygen Water Warmth

Why does adding sugar or salt preserve food?

Removes water using osmosis

Name 2 uses of decomposing microbes?

Making compost Breaking down sewage

How does carbon get into plants?

Photosynthesis

List 3 ways carbon is put back into the atmosphere?

Respiration by animals Respiration by plants Respiration by decomposers (decomposition) Combustion

Why is there more carbon dioxide in the atmosphere in the winter?

Less photosynthesis (fewer leaves) More combustion (heating)

What other element is recycled in nature?

nitrogen
