What do the arrows mean?
They show the direction that the energy is passing through the system. It shows which organism is getting its energy by eating.Slide5

What is a niche?
What is an earthworm’s niche?
It is a decomposer, and is food for some birds and other organisms.
What is the niche of a tree?
It is a producer, it provides oxygen and provides shade.Slide15
What is the carrying capacity of the graph?Slide16
What is the carrying capacity of the graph?Slide17
What is the carrying capacity of the graph?Slide18
What is the carrying capacity of the graph?Slide19
What is the carrying capacity of the graph?Slide20
When an ecosystem has reached its carrying capacity, it is said to be in equilibrium. What does that mean?
The system is in
balance.
It has the necessary number of each organism living there to keep it going.Slide21
What is the carrying capacity of the graph?Slide22
Which of the following would be a limiting factor to a population of rabbits
A- Decrease in rainfall B- Increase in Birth Rate
C- Increase in Predators D- Increase in fish population
E- Drought F- A new disease in the rabbit population
G- Increased Rain H- Less Shade
I- Decrease in Predators J- More Plants
K- Decrease in Habitat L- Decrease in birth rate
M- Climate (weather) Change
Answer:
A, C, E, F, K,MSlide23
Why do grazing animals stay in herds?
For protection against predatorsSlide24
Where is most energy found in any food web, food chain or energy pyramid. What types of organisms produce the most energy for an ecosystem?
Producers (plants)Slide25
Which organisms provide the least energy to an ecosystem?Slide26
Eagles- higher level consumersSlide27
Which organisms provide the most energy?
plantsSlide28
Which organisms are primary consumers?
Deer, Beetle, Small FishSlide29
Which are secondary and tertiary consumers?
Frog, Large Fish, Turtle, Dragon Fly, EagleSlide30
The study of the environment is called:
ECOLOGYSlide31
The study of the environment and how living things interact is called
Ecology
An example of an
abiotic factor
would be
Soil
Air
Light
Temperature
waterSlide32
An ecosystem is made up of
Living
things and the physical environment
In an energy pyramid, the bottom level represents
Producers/ Plants
In an energy pyramid, the
top
level
represents
Higher level consumers
In an energy pyramid, the
greatest amount of energy is found in
ProducersSlide33
A__________ will
eat plants
herbivore
A__________ will eat meat
carnivore
A__________will
eat both plants and animals
omnivore
Which direction of arrows in a
food chain
would be correct?
plant
insect bird
plant insect bird bird insect plantSlide34
The arrows in a food chain represent
transfer of energy
The living parts of the environment only make up a(n)
community
A group of the same species in an area make up a(n)
population
Name some limiting factors to plants and animals
space, shelter, food, water, light, disease, predatorsSlide35
When a population cannot grow any larger it has reached its
carrying capacity
Grazing in herds benefits populations of deer because
it protects them from predators
The purpose or place an organism has in its environment is called its
niche
The specific place that meets the needs of a living organism is its
habitat
What are the 5 basic needs of all living organisms
food, water, shelter, space, arrangement
Which is most complex: Organism, population, community, ecosystem
EcosystemSlide36
The purple loosestrife is found in some wetland ecosystems. This invasive
species does what to biodiversity?
Decreases it
An example of a
nonrenewable
resource
is
coal, petroleum, gas, oil, anything mined from the Earth (gold, silver…)
An example of a
renewable
resource
is
air, sunlight, trees, food, water
Using the same resources again and again is called
recycling
An example of an alternative energy source is wind solar Hydroelectric (water) Geothermal (Earth’s heat)Slide37
A substance that makes air, water or land unfit for life is called a(n
)
pollutant
The many ways that humans can use natural resources without using them up are
called
sustainable practices
A population of an organism is in equilibrium when it has reached its
carrying capacity
If organisms are considered so similar that if they can produce offspring that can also produce offspring, they are considered a(n
)
species
Primary consumers eat
plants
An ecosystem differs from a community because a community
includes only the living things Slide38
What are examples of items that could be conserved:
water, air, renewable and nonrenewable resources
Things that would increase biodiversity would be
higher birth rate
more water
more food
new species not placed there by humans
