Energy Transfer in the Biosphere

Question 1

All organisms need what to live?

Answer 1

Energy

Question 2

What is the first law of thermodynamics?

Answer 2

The first law of thermodynamics is that energy cannot be created or destroyed

Question 3

If energy can not be created, where did the energy came from?

Answer 3

The sun

Question 4

What is Albedo?

Answer 4

Albedo refers to the amount of energy reflected by the clouds, water, and land.

Question 5

Energy can be converted into different forms. Radiant energy from the sun that does reach the earth is converted into various forms of usable energy by living things.

Answer 5

Energy can be converted into different forms. Radiant energy from the sun that does reach the earth is converted into various forms of usable energy by living things.

Question 6

List the path of energy flow through our biosphere in order

Answer 6

Sun, plants, glucose, animals, ATP

Question 7

The portion of the sun’s energy that reaches the ground is used by..

Answer 7

Producers for photosynthesis (producer = plants)

Question 8

Producers (plants, algae and some bacteria) converts radiant energy into..

Answer 8

Chemical energy

Question 9

Chemical energy is stored in the bonds of

Answer 9

Carbohydrates / Glucose

Question 10

After producers make chemical energy, the energy is stored in glucose which is used to..

Answer 10

fuel cellular activities like cellular respiration

Question 11

Autotrophs are also known as..

Answer 11

producers. They use the sun to create they’re own food

Question 12

What is different kind of producer?

Answer 12

Chemosynthesis

Question 13

Microorganisms who lives under deep dark sea without light uses what to produce their own carbohydrate based energy?

Answer 13

they use hydrogen sulphide to produce their own carbohydrate energy

Question 14

what is the chemosynthesis formula?

Answer 14

CO2 + 4 H2S + O2 –> CH2O + 4 S + 3 H2O

Question 15

What is ecology?

Answer 15

A study of interactions between organisms and their environment

Question 16

List the 4 ecology in order from smallest to largest

Answer 16

Organism, population, community (more than one population make a community) and ecosystem

Question 17

The product of chemosynthesis is..

Answer 17

sulphuric acid instead of oxygen

Question 18

In cellular respiration, how does consumers obtain energy?

Answer 18

Eating producers or other consumers

Question 19

ATP from cellular respiration is burned to..

Answer 19

power our cellular process

Question 20

When ATP from cellular respiration is burned to transform to usable energy, what are the 2 energy?

Answer 20

Kinetic energy (for us to move) and thermal energy (to keep us warm)

Question 21

Heterotrophs are consumers that..

Answer 21

obtain their energy from other organisms (eating them)

like secondary consumers and tertiary consumers

Question 22

In fermentation, anaerobic environments with heterotrophs (usually bacteria) are able to perform cellular respiration w..

Answer 22

without oxygen

Question 23

Anaerobic bacteria that produces different by-products is a result of..

Answer 23

fermentation

Question 24

List the 4 consumers

Answer 24

Primary consumers, secondary consumers, tertiary consumers and decomposers

Question 25

Primary consumers do not get their energy from consumers, they get it from..

Answer 25

eating plants ( herbivores - organisms that only eat plants)

Question 26

Secondary consumers get their energy mainly from eating consumers, they get it from eating..

Answer 26

herbivores ( Omnivores or carnivores)

- ex. Spiders, frogs (eats insects and some plants)

Question 27

Tertiary consumers are organisms that eat..

Answer 27

Carnivores ( TRUE carnivores)

- ex. lions, wolves (they only eat animals)

Question 28

Decomposers are organisms that take..

Answer 28

left overs or waste matter

- ex. bacteria, some insects (they eat the left over dead bodies)

Question 29

How does energy cycle?

Answer 29

Energy is taken from sun, producers take sun energy and convert to glucose and oxygen through photosynthesis.

Consumers take glucose through cellular respiration and release carbon dioxide and water (which producers need to perform photosynthesis)

then it cycles
