Matter?It’s crowdedup in here!
This is the source of all energy in an ecosystem
The sun
This is the name given to all the living parts of the environment
Biotic Factors
Water, temperature, and air are this type of factors
Abiotic
This is the name given to organisms that make their own
food, from solar energy
Producers/autotrophs
What is another name for a consumer?
Heterotroph
This is the type of relationship between a flea and a dog
Parasitism
Bacteria in the stomachs of cows help cows digest their food. We
describe this as this type of relationship…
Mutualism
This word is used to describe how organisms interact with one
another we define it as “living together”
Symbiosis
An orchid can use a tree trunk to receive extra nutrients, it does not hurt the tree by growing on it…
this is an example of:
Commensalism
A lion may hunt a zebra. They belong to different trophic levels. Name what type of consumer the
lion and zebra would be?
Lion= secondary consumerZebra= Primary consumer
What do the arrows represent in a food chain
Grass Rabbit Fox
Energy transfer
This is the name given to organisms that eat both animal
and plant material
Omnivores(Tertiary Consumers)
Animals that eat plants only are called
Herbivores(Primary consumers)
Organisms that include bacteria and fungi are called:
Decomposers
How many herbivores are in the food web above?
Three: Grasshopper, squirrel and rabbit
This is what we call anything that takes up space
Matter
Give an example of types of matter that get recycled in the
environment
Water, Carbon
At
In an energy pyramid, organisms at the top only get a certain amount of energy, because most energy is lost as heat and waste material. What do
we call this rule?
10 % Rule
What happens to all the matter that exists on earth?
It gets recycled
What process shown above, decreases the amount of carbon
dioxide in the air?
Photosynthesis
As a predator population increases, what happens to the prey population?
Decreases
What do we call this type of growth?
Exponential (J-curve)
What is another name for carrying capacity ?
(K)
Space, births, mates, food are considered this type of factors….
Density-Dependent
What does the dashed line represent?
Carrying capacity (K)
