energy and matter exchange

Question 1

open system

Answer 1

allows energy and matter to enter and exit the system

Question 2

closed system

Answer 2

allow only energy (not matter) to enter and exit the system (earth is an example of a closed system)

Question 3

lithosphere

Answer 3

the land part of the biosphere

Question 4

hydrosphere

Answer 4

the water part of the biosphere

Question 5

atmosphere

Answer 5

the air part of the biosphere

Question 6

producers

Answer 6

organisms that use the suns energy to perform photosynthesis and produce their own food

Question 7

consumers

Answer 7

organisms that cannot make their own food but consume other organisms to obtain energy (you know the three types)

Question 8

the sun

Answer 8

is the main source of energy for most producers

Question 9

albedo

Answer 9

the amount of light reflected back to space. if something has high albedo more reflection, low albedo less reflection (clouds)

Question 10

greenhouse gases

Answer 10

gases in the atmosphere like water vapour and CO2

Question 11

oceans and land (energy absorption)

Answer 11

most of the energy coming from the sun is absorbed by earths surface

Question 12

how much sun energy actually reaches the earth?

Answer 12

1-2%

Question 13

chemosynthesis

Answer 13

the process for deep sea creatures to receive energy since the sun can’t reach down that deep.
bacteria inside tubeworms are able to absorb energy stored in the bonds of hydrogen sulfide coming from deep sea vents

Question 14

trophic levels

Answer 14

describe feeding relationships in the ecosystem that allow the passing of energy

Question 15

producers

Answer 15

also called autotrophs and are typically photosynthetic organisms that use light to create sugars (plants)

Question 16

consumers (trophic structures)

Answer 16

also called heterotrophs that directly or indirectly depend on producers for food
