How are plant cells different from animal cells?

plant cells have cell wall, large vacuole, and chloroplasts

Based on this energy pyramid, which would get the most energy from producers

primary consumers because producers have most energy

Which body system is responsible for the movement of blood throughout the body?

circulatory system including the heart, blood and vessels

Which would be the last to receive energy in an energy pyramid.

decomposers, they get energy when things die

What might you expect to happen if a drought kills all producers in an ecosystem?

The ecosystem would collapse from lack of energy

Why can two girls from same parents have different eye and hair color, and be different heights

each child inherits random traits from mother and father

What is the function of the decomposers in the environment?

recycle elements used by producers to make chemical energy

Which of the following represents the correct flow of energy in this food chain?

producer, primary, secondary, tertiary, quanternary consumer

Based on this food chain, which organism receives the least amount of energy

Hawk, energy transferred is smaller as you go up food chain

As you move from the bottom of the energy pyramid to the top,

the energy available is reduced by 90% at each level

What is the one things essential for all food chains and food webs?

light energy - producers can't make food without sunlight

Which organism(s) captures 100% of the energy used in this food web.

green plants because they get all their energy from the sun

Which organism has the highest energy concentration

phytoplankton because they get energy directly from the sun

Answers

1
How are plant cells different from animal cells?
plant cells are round, small vacuole, chloroplasts, lysosome
animals cells have cell wall, large vacuole, chloroplasts
animal cells have cell wall and plant cells do not.
plant cells have cell wall, large vacuole, and chloroplasts
2
Based on this energy pyramid, which would get the most energy from producers
tertiary producers because they produce more
primary producers because they produce the energy
primary consumers because producers have most energy
tertiary consumers because they are the largest animals
3
Which of the following is the correct path of energy flow in the food web?
grass, grasshopper, mouse
grass, mouse, owl
grass, rabbit, owl
grass, grasshopper, owl
4
Which body system is responsible for the movement of blood throughout the body?
respiratory system because it includes blood
digestive system because it includes the heart for pumping
circulatory system including the heart, blood and vessels
nervous system because it controls the heart
5
How much of the energy the grasshopper got from grasses, will go to the bird
100%
1%
10%
50%
6
Which would be the last to receive energy in an energy pyramid.
tertiary consumers like the mackerel
decomposers, they get energy when things die
tertiary consumers like the shark
producers like the phytoplankton
7
As you move through a food chain, the correct order of energy flow is
producer, omnivore, herbivore
producer, herbivore, carnivore
carnivore, omnivore, herbivore
producer, omnivore, carnivore
8
What might you expect to happen if a drought kills all producers in an ecosystem?
The herbivores would die also, but consumers would survive
smaller plants would grow because of lack of water
The omnivores would eat carnivores for energy
The ecosystem would collapse from lack of energy
9
Why can two girls from same parents have different eye and hair color, and be different heights
each child inherits random traits from mother and father
these traits are random in girls
these traits can be selected before birth of child
these are traits that are controlled by the environment
10
In this energy pyramid, energy flows from
backswimmer, sunfish, heron
Sunfish, bass, heron
Cattail, sunfish, bass
Algae, sunfish, heron
11
What is the function of the decomposers in the environment?
they make sure things are really dead not sleeping
recycle elements used by producers to make chemical energy
destroy dead organisms so they don't cover the Earth
they release heat energy from dead organisms to environment
12
Which of the following represents the correct flow of energy in this food chain?
producer, primary, secondary, tertiary, quanternary consumer
primary, secondary, tertiary producers, consumers, herbivore
producer, primary, secondary, tertiary consumers, herbivores
producers, secondary, tertiary consumers, heterotrophs
13
Based on this food chain, which organism receives the least amount of energy
grasses because it get energy from the sun
Hawk, energy transferred is smaller as you go up food chain
all levels get same amount of energy
Frog because it eats small insects
14
How much of the frog's energy will go to the snake?
1%
10%
100%
50%
15
As you move from the bottom of the energy pyramid to the top,
the energy increases to support more animals
the energy available is reduced by 25% at each level
the energy available is reduced by 90% at each level
the energy at each level is the same
16
What is the one things essential for all food chains and food webs?
oxygen - producers can't make food without this element
light energy - producers can't make food without sunlight
oxygen - consumers can't survive without oxygen
water - nothing can live without water
17
Which organism(s) captures 100% of the energy used in this food web.
rabbit and grasshopper because they eat green plants
Rabbit because it get all the energy from plants
caterpillar because it eats green plants
green plants because they get all their energy from the sun
18
In secondary succession, what is the most stable stage of development?
grasses and shrubs
softwood forest
Pine wood forest
hardwood forest
19
Which organism has the highest energy concentration
crustaceans because they eat the producers
phytoplankton because they get energy directly from the sun
all are the same in an energy pyramid
sharks because they are the largest and eat the most
20
The starting source of energy for this energy pyramid is
Diatoms
sunlight
ocean water
copepods
21
Passage of genetic information from one generation to the next is
animal husbandry
heredity
selective breeding
adaptation
