Food webs are different than food chains because___________

The water cycle includes which of the following steps?
Precipitation
Carbon dioxide
Evaporation
Condensation
Consumers
The carbon cycle includes which of the following steps:
Carbon dioxide
Carbon monoxide
Producers
Evaporation
Consumers
The main source of energy is:
Salad
Producers
The sun
Decomposers
Why is the carbon cycle important?
It's not- there is no reason for it
If carbon did not cycle, it would be used up and everything that needs carbon (aka like everything) would die
Without water, we would all be thirsty
Without carbon, we would all be tired
Which of the following is an example of a decomposer?
A mushroom
A tree
A zebra
A cactus
Pollution is __________________
The release of helpful chemicals into the environment
The release of harmful chemicals into the environment
The protection of species and resources
Niche
Energy from the sun is transfered to organisms by_________
Winning rock, paper, scissors
Energy flow
Condensation
Carbon dioxide
Lions and tigers eat from the same zebra population. This is an example of:
Symbiosis
Condensation
Competition
Same snack shop
Conservation is____________
Difficulty thinking
Unable to protect the environment
Protecting and restoring species and resources
Throwing trash out your car window
All of the following are examples of pollution except:
Littering
Smog from factories
Reusing your water bottle and not getting a new one from the front desk every day
Getting a plastic water bottle from the front desk every day.
Cutting up paper for fun then leaving it all around the classroom
How does pollution cause an imbalance to the environment?
The harmful chemicals allow plants to grow
The harmful chemicals get into the soil and prevent plants to grow
The air gets angry and causes rain
The competition between niches prevents conservation
Deforestation can cause:
The loss of animal habitats
Nothing, it's beneficial to the environment
There is a lack of oxygen produced because there are no trees
The air becomes unhealthy because it cannot be filtered through the trees
What would cause an imbalance to a forest habitat?
What is the difference between restoration and prevention
Restoration is returning something to its original form and prevention is allowing something harmful to happen
Restoration is returning something to its original form and prevention is keeping something harmful from happening
Restoration is to keep something from happening and prevention is returning something back to normal
There is no difference, they're the same thing
