Q

what does a plant use up

A

Q

how does a plant lose energy

A

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)

Q

How is energy gained in an animal

A

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

17
Q

The animal’s energy is stored

A

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

18
Q

the energy is lost as

A

faeces or urine… yk waste

19
Q

How do animals lose energy

A

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)

20
Q

What to do next(not a real question)

A

Look at the pics on slides for better demonstration

21
Q

What happens to each subsequent trophic level

A

Less energy is available to each

22
Q

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

A

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

23
Q

Predators are usually ______ than prey and…

A

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

24
Q

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

A

a pyramid of numbers

25
Q

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

A

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

26
Q

what can be overcome by using a pyramid of numbers

A

the disadvantage/ limitation

27
Q

a pyramid of numbers is essentially what type of chart

A

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

28
Q

The area of each bar is…

A

proportional to the number of organisms at each trophic level

29
Q

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

A

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