28
Q

Invasive species

A

Is a species that takes over a habitat, ecosystem,or territory

29
Q

How did the zebra mollusels arrive to the great lakes

A

They hitched on a cargo ship from Europe

30
Q

How are zebra mussels harmful to humans?

A

Because damage to boats and docks clogged waterways and litter beaches. They don’t even taste good

31
Q

How do zebra mussels affect food webs?

A

They cut off the food supply from other hard shelled organisms by attaching to them. Since they are filter feeders, they clear out huge bodies of water removing food for native invertebrates and small fish

32
Q

Biosphere

A

The regions of the surface and atmosphere and hydrosphere

Q

Population

A

A group of the same species living in a particular area

A

Organisms that can eat both primary and secondary consumers

A

Organisms that break down dead organisms

40
Q

Energy pyramid

A

A model that shows the flow of energy

41
Q

Relationship Web

A

An inner circle of close relationships and the outer circle

42

A decomposer that eats dead or decaying matter like earthworms, millipedes and dung beetle

43

Producer

46
Q

Type?Autotroph

A

producer - makes its own food by using photosynthesis

47
Q

Type?
Heterotroph

A

Consumer that is a A heterotroph is an organism that can’t make its own food and must get energy by eating other plants and animals. Examples of heterotrophs include:Herbivores: Eat only plantsCarnivores: Eat only other animals or meatOmnivores: Eat both plants and animalsDecomposers: Break down dead organisms or their waste products into nutrients for soilDetritivores: Eat detritus which is dead or decaying matter

48

53
Q

Where does all the energy in an ecosystem come from?

A

The energy from an ecosystem comes from the sun

54
Q

In a food web what do the arrows represent? And which way do arrows point?

A

To show which animals eat the other like a food chain or a food web

55
Q

What is the role of plants in a food web?

A

The role of the plants in the food web is to make their own food by doing photosynthesis

56
Q

What does competition mean in terms of a food web?

A

That means the two animals will compete for the same resources

57
Q

Can an organism be a consumer at multiple levels in an ecosystem?

A

An organism can be a different trophic levels this occurs when an organism is an omnivore which means it consumes both plants and animals

58
Q

Why are decomposers important to the food web and ecosystem?

A

They decompose the dead organisms so they can give nutrients to the soil so they can make more green plants

59
Q

A bean plant is an autotroph because it…

A

A bean plant is an autotroph because it produces his own food by using photosynthesis and other chemicals
