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
Define transpiration
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
What is the difference between evaporation and transpiration
If operation occurs in water becomes paper from bodies of water transportation occurs when water leaves a plant as vapor
26
Name a type of succession that would take place it's a fire destroyed forest
Secondary succession
27
Name a type of succession that would take place is a volcano erupted
Primary succession
28
Describe the 10% rule
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
Is a rabbit a heterotroph are in autotroph
Rabbits are heterotrophs
30
What are the characteristics of living things
``` Growth Reproduction Metabolism Stimuli DNA or genetic material Cell organization Evolution ```
31
Give an example of a producer
Grass
32
Give an example of a consumer
``` Dear wolves Bears grasshoppers hocks ```
33
What is one major difference between a producer and consumer
Producers are autotroph's and consumers are heterotrophs
34
Give me example of a herbivore
Deset
35
Give an example of a carnivore
Wolves
36
Give an example of an omnivore
Bears and rats
37
Give an example of a scavenger
Vultures and raccoons
38
Give an example of a decomposer
Bacteria and fungi
39
What is a detritivore
An animal that feeds on dead organic material especially plant detritus
40
Give an example of a detritivore
Earthworms
41
Three reasons why decomposers are vital to an ecosystem
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
An example of mutualism
Digestive bacteria and humans | The bacteria stays alive the humans get get help with the process of digestion
43
An example of commensalism
Birds and trees
44
An example of parasitism
Wasp larvae and Catapillar | Tick and dog
45
What is an example of predation
Tigers hunting buffalo
46
why is bio diverse city important
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
What are the three main components of the water cycle
Evaporation condensation and precipitation
48
When it rains on land one of three things will happen to that water named those three possibilities
Infiltration Run off Transpiration
49
What is the relationship between photosynthesis and respiration in the carbon cycle?
Photosynthesis converts CO2 into O2 , Respiration does exactly the opposite bonding carbon with O2 to make CO2
50
Name three ways humans impact the carbon cycle
Urbanization Forest fire Burning fossil fuels
