Energy Flow

Question 1

Say it with me: All organisms need _____

Answer 1

ENERGY!!!!!!

Question 2

How and what do plants use energy from?

Answer 2

Plants use energy from the

Sun during photosynthesis

Question 3

What is burnt and when? (vague ik)

Answer 3

The glucose is then used to make carbohydrates, proteins, lipids and everything else the plant needs.

Question 4

autotrophs

Answer 4

make their own food (plant)

Question 5

heterotrophs

Answer 5

need ready made food

Question 6

A plant’s proteins, lipids, etc. become…

Answer 6

the components of food for consumers

Question 7

Food is a store of…

Answer 7

chemical potential energy

Question 8

How do consumers obtain their food?

Answer 8

from food made by plants, either directly or indirectly

Question 9

As consumers feed on plants, what is passed to them?

Answer 9

BACK TO ENERGYYYY

Question 10

What is used to support all life processes?

Answer 10

the energy released from food

Question 11

what does respiration do?

Answer 11

Respiration releases the chemical energy stored in food so that it can be used by the organism

Question 12

when does a plant gain energy?

Answer 12

A plant gains energy when it converts light energy to chemical potential energy during photosynthesis

Question 13

what does a plant store

Answer 13

It stores some of the energy by changing the glucose into carbs, lipids and yk other said chemicals

Question 14

what does a plant use up

Answer 14

it uses up some of the food during respiration to let go energy to grow and carry out other life processes (I process life sometimes… all the time)

Question 15

how does a plant lose energy

Answer 15

some of the energy released is lost and labelled as as heat energy in respiration (sarcasm ugh labels smh stop labeling things plants have feeling too yk)

Question 16

How is energy gained in an animal

Answer 16

energy is gained as the animals feeds (FEEDING TIMEEE… bro I’m hungry

Question 17

The animal’s energy is stored

Answer 17

as it grows (grow grow grow ur… animal? gently down the… land?/sea)

Question 18

the energy is lost as

Answer 18

faeces or urine… yk waste

Question 19

How do animals lose energy

Answer 19

Some of the stored energy is released during respiration for the organism to stay alive… yk live, sumn I’ve never done… and some of the energy is lost as heat to the environment (is it hot in here or is it just an animal losing stored energy am I right)

Question 20

What to do next(not a real question)

Answer 20

Look at the pics on slides for better demonstration

Question 21

What happens to each subsequent trophic level

Answer 21

Less energy is available to each

Question 22

Ecosystems usually contain a _____ number of small organisms and a ______ number of large animals

Answer 22

large number of small organisms and a smaller number of large animals

Question 23

Predators are usually ______ than prey and…

Answer 23

Predators are usually larger than their prey and must eat a number of them to stay alive

Question 24

All of the number of organisms info we talked about so far can be represented in a diagram called

Answer 24

a pyramid of numbers

Question 25

Do food chains depict the number of organisms at each trophic level

Answer 25

No cuz then they’d be num (numeral) chain, k bad puns I’ll stop haha

Question 26

what can be overcome by using a pyramid of numbers

Answer 26

the disadvantage/ limitation

Question 27

a pyramid of numbers is essentially what type of chart

Answer 27

a bar chart that is plotted horizontally /in, obviously, a pyramid formatting

Question 28

The area of each bar is…

Answer 28

proportional to the number of organisms at each trophic level

Question 29

Where are the producers and consumers placed on a pyramid of numbers

Answer 29

The producers are placed at the base of the pyramid and each successive consumer level is placed above them
