Question 15

food chains are

Answer 15

diagrams that show the movement of
energy/nutrients through an ecosystem.

Question 16

(food chains) producers are

Answer 16

always the first organisms in a food chain

Question 17

(food chains) producers capture..

Answer 17

the energy from the sun, (source of
energy for all living things), through the process of photosynthesis, and make it available to the other organisms of the community, these are the plants

Question 18

(food chains) consumers are

Answer 18

organisms that eat food. This transfers energy/nutrients
from the organism eaten to the organism eating it

Question 19

Primary Consumer

Answer 19

these are herbivores. Energy/nutrients is
transferred from plants to the herbivores

Question 20

Secondary Consumer

Answer 20

these are carnivores. Energy/nutrients
are transferred from the prey organisms to the predator/
scavenger.

Question 21

Decomposers

Answer 21

These organisms break down dead organisms and the wastes
produced by organisms and return these materials to the
environment.

These organisms are the bacteria of decay and fungi

Question 22

Food webs are made up of

Answer 22

many food chains that overlap

Question 23

food webs are

Answer 23

what we actually find in nature, as most living things
have more that one food source.

Question 24

Like food chains, food webs show

Answer 24

the transfer of nutrients and
energy through an ecosystem

Question 25

For all the pyramids, the _______ are always at the bottom

Answer 25

producers

Question 26

(pyramid) producers have the

Answer 26

most energy, biggest population, and the most biomass

Question 27

As we move up the pyramid,

Answer 27

the amount of energy, size of
population, and biomass gets smaller

Question 28

The second level of any pyramid, just above the producers, is always the

Answer 28

herbivores

Question 29

The remaining levels of the pyramids are made up of

Answer 29

carnivores

Question 30

the top level of the food chain being made up of one

Answer 30

dominant
carnivore (apex predator)

Question 31

The pyramid of energy demonstrates

Answer 31

how much energy is
needed to support the level above it.

Question 32

About 10% of the energy that moves up a level..

Answer 32

is stored. The
remainder is lost to metabolism.

Question 33

The base of the pyramid, the ______ are known as

Answer 33

autotrophs

the first trophic level.

Question 34

the base of the pyramid has the most

Answer 34

energy

Question 35

The second level of the pyramid, the ________ are

Answer 35

heterotrophs

the second trophic level.

Question 36

The third level is the

Answer 36

third trophic level,
and so on.

Question 37

The pyramid of numbers demonstrates

Answer 37

the number of
organisms needed to support the level above it

Question 38

(pyramid of numbers) Like the pyramid of energy,

Answer 38

the autotrophs are on the bottom,
base, the second level is made up of the herbivores, and the
top levels are carnivores.

Question 39

In ecology, biomass refers to

Answer 39

the organic material found in
living things

Question 40

The pyramid of biomass demonstrates

Answer 40

how much biomass is
needed at each level to support the level above it

Question 41

(pyramid of biomass) Like the pyramid of energy, the plants make up the

Answer 41

base of
the pyramid, the herbivores make up the second level, and
the carnivores make up the top levels.

Question 42

There is a limited amount of _____ on the Earth

Answer 42

material

Question 43

There is a need to recycle materials, otherwise

Answer 43

we would run
out of these materials and life would no longer exist.

Question 44

There are material cycles for

Answer 44

all materials

Question 45

Three examples of material cycles are the

Answer 45

carbon cycle,
water cycle, and nitrogen cycle

Question 46

(carbon cycle)
The storage area for carbon is

Answer 46

in the atmosphere in the form
of carbon dioxide.

Question 47

(carbon cycle)
Carbon is pulled out of the air by

Answer 47

plants, through the process
of photosynthesis, and they make the carbon available to the
other organisms of the ecosystem in the form of sugars and
starches.

Carbon is then moved through the ecosystem when animals
consume food

Question 48

(carbon cycle)
Carbon is returned to the atmosphere in the form of

condensation + precipitation

the water falls to the Earth

Question 52

(water cycle)

Water not absorbed or stored on the Earth returns to

nitrogen-fixing
bacteria. This bacteria makes nitrogen available to plants.

The nitrogen compounds are then transferred through the ecosystem when the organisms consume one another

Question 56

(nitrogen cycle)

Answer 56

dead organisms and their wastes, releasing simple nitrogen
compounds into the soil for plants to use

Question 57

(nitrogen cycle)

Answer 57

dead organisms and wastes. These bacteria return the nitrogen
back to the atmosphere.

Question 58
