Presentation transcript:

Eco-friendly A special relationship Web Browser What’s the Matter? It’s crowded up 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 consumer Zebra= 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)
