Answer 15

The more herbivores can be supported

Question 16

When comparing NPP,

We are measuring the change in a ecosystem

Question 17

When comparing NPP,

Answer 17

We are measuring the change in a ecosystem

Question 18

Consumer

Answer 18

An organism that is incapable of photosynthesis and must therefore obtain energy by consuming other organisms ( Hetertroph Herbivore)

A consumer that eats other consumers

Question 21

Carnivore

Answer 21

A consumer that eats other consumers

Question 22

Secondary Consumer

Answer 22

A carnivore that eats primary consumers

Tertiary Consumer

Answer 23

A carnivore that eats secondary consumer

Question 24

Tropic Levels

Answer 24

Transfer of matter and energy; successful level of organisms consuming one another

Question 25

Food chain

Answer 25

The sequence of consumption from producers through tertiary consumers

Question 26

Scavenegers

Answer 26

An organism that consumes dead animals (wait till something already dead)

Question 27

Scavenegers

Answer 27

An organism that consumes dead animals (wait till something already dead)

Question 28

Detrivore

Answer 28

An organism that specializes in breaking down tissue and waste products into smaller pieces (dead but eat smaller animals)

Question 29

Decomposters

Answer 29

Fungi and bacteria that complete the breakdown process by converting organic matter into small elements and molecules that can be recycles back into the ecosyem (chemically break down food first)

Question 30

Decomposters

Answer 30

Fungi and bacteria that complete the breakdown process by converting organic matter into small elements and molecules that can be recycles back into the ecosyem (chemically break down food first)

Question 31

Ecological Efficenty

Answer 31

The proportion of consumed energy that can be passed by one trophic level to another

Question 32

Ecological Efficenty

Answer 32

The proportion of consumed energy that can be passed by one trophic level to another

Question 33

10 % rule

Answer 33

Of the total biomass available of the given trophic level, only about 10% (5-25%) can be converted into enegery at the next given higher trophic level

Question 34

Trophic Pyrimaid

Answer 34

A representation of the distribution of biomass, numbers, or energy amoung trophic levels

Question 35

Food Web

Answer 35

A model of how energy and matter move through 2+ interconnected food chains

Question 36

Food Web

Answer 36

A model of how energy and matter move through 2+ interconnected food chains

Question 37

When do feedback loops occur?

Answer 37

When the result of a process returns back to the system and change the rate of process
(Positive and negative feedback loops)

Question 38

Positive feedback loops

Answer 38

• Move to an extreme
• good and bad

Question 39

Negative feedback loops

Answer 39

• Stabalizes a system
• EX: Air COnditioner
