Q

What is the role of the decomposer in an ecosystem

A

Decomposers breakdown dead plants and animals they also break down the waste of other organisms
If decomposers weren’t an ecosystem the plants would not get essential nutrients and dad matter and waste would pileup

Q

Define evaporation

A

Changing of the liquid into a gas often under the influence of heat

21
Q

Define condensation

A

The conversion of a vapor or gas to a liquid

22
Q

Define pprecipitation

A

Water that falls to the ground as rain snow etc.

23
Q

Define collection/run off

A

Water from rain or snow that flows over the surface of the ground into streams

24
Q

Define transpiration

A

Transpiration is the process where plants absorb water to the roots and then give off water vapor through pores in their leaves an example of transpiration is going to plant absorbs water in its roots

25
Q

What is the difference between evaporation and transpiration

A

If operation occurs in water becomes paper from bodies of water transportation occurs when water leaves a plant as vapor

26
Q

Name a type of succession that would take place it’s a fire destroyed forest

A

Secondary succession

27
Q

Name a type of succession that would take place is a volcano erupted

A

Primary succession

28
Q

Describe the 10% rule

A

It states that energy when passing from prey to predator is only concert rated at about 10%. For example, when do you eat the grass only 10% of the energy that the grass received from the sun is passed onto the dear

29
Q

Is a rabbit a heterotroph are in autotroph

A

Rabbits are heterotrophs

30

A 
Growth
Reproduction
Metabolism
Stimuli

Cell organization
Evolution
31
Q

Give an example of a producer

A

32
Q

Give an example of a consumer

A 
Dear
 wolves 
Bears 
grasshoppers
 hocks
33
Q

What is one major difference between a producer and consumer

A

Producers are autotroph’s and consumers are heterotrophs

34
Q

Give me example of a herbivore

A

Deset

35
Q

Give an example of a carnivore

A

Wolves

36
Q

Give an example of an omnivore

A

Bears and rats

37
Q

Give an example of a scavenger

A

Vultures and raccoons

38
Q

Give an example of a decomposer

A

Bacteria and fungi

39
Q

What is a detritivore

A

An animal that feeds on dead organic material especially plant detritus

40
Q

Give an example of a detritivore

A

Earthworms

41
Q

Three reasons why decomposers are vital to an ecosystem

A

Breakdown animal waste and dead organisms and released free nutrients back into the ecosystem
Break down the dead organisms to where the scavengers can eat the organism that was broken down without the decomposers scavengers will die
Breakdown organics into nutrients which can be used by living organisms to create new life

42
Q

An example of mutualism

A

Digestive bacteria and humans

The bacteria stays alive the humans get get help with the process of digestion

43
Q

An example of commensalism

A

Birds and trees

44
Q

An example of parasitism

A

Wasp larvae and Catapillar

Tick and dog

45
Q

What is an example of predation

A

Tigers hunting buffalo

46
Q

why is bio diverse city important

A

Biodiversity boost economic productivity were each species, no matter how small, I’ll have an important role to play. For example, a large number of plant species needs a greater variety of crops. Greater species diversity is insures natural sustainability for all lifeforms
They help keep our lives in balance and regulate the climate

47
Q

What are the three main components of the water cycle

A

Evaporation condensation and precipitation

48
Q

When it rains on land one of three things will happen to that water named those three possibilities

A

Infiltration
Run off
Transpiration

49
Q

What is the relationship between photosynthesis and respiration in the carbon cycle?

A

Photosynthesis converts CO2 into O2 , Respiration does exactly the opposite bonding carbon with O2 to make CO2

50
Q

Name three ways humans impact the carbon cycle

A

Urbanization
Forest fire
Burning fossil fuels
