Energy transfer

Question 1

Why are all living things dependent on the sun?

Answer 1

Because plants make glucose and oxygen via photosynthesis using the sunlight. So in other words plants make their own food but need the sun to make it work. All living things need oxygen and plants contain energy so primary consumers will eat it and gain energy essential for life.

Question 2

What is an alternate way of transferring energy?

Answer 2

When organisms die microorganisms break them down. These are called decomposers or detritvores.

Question 3

What do plants use sunlight for?

Answer 3

Growth, photosynthesis and respiration

Question 4

When consumers eat plants, where is some of the energy inputted?

Answer 4

Growth, movement, respiration and excretion. (faeces, urine)

Question 5

How do you calculate efficiency of energy?

Answer 5

energy at next stage/energy at last stage *100
