Answer:
Yes, One can is enough to cover the wall.
Explanation:
Given - Adalyn's mom is painting a wall in her bedroom with chalkboard
paint. If the dimensions of the wall are 12 feet by 9 feet and one
can of paint covers up to 110 square feet.
To find - Will one can be enough to cover the wall ? Explain.
Proof -
Given that ,
Dimensions of the wall are 12 feet by 9 feet .
Also,
One can of paint covers up to 110 square feet.
Now,
We know that Area of wall should be painted.
So, firstly we find the area of the wall.
Now,
Area = 12×9 feet²
= 108 feet²
⇒Area of wall = 108 feet²
Now,
As Area of the wall (108 feet²) < One can of paint covers (110 feet²)
∴ we get
One can is enough to cover the wall.

Answer:
True, several ecosystems have been damaged thus conserationalist focus on protecting several species.
Explanation:
- As the ecosystem is not only a part of land found on the earth it involves the entire system of the mountain to oceans to the atmosphere to the food web and even the humans. Thus ecologists and biologists are aware of the fact that man for his selfish needs has destroyed the natural carrying capacity of the ecosystem beyond repair.
- Thus conservationists focus on protecting the entire chain of species as all are linked to the same biotic community and hence live in harmony and coexistence of each other.
- By keeping these species protected the balance of energy flow in the ecosystem will remain stable and population of these species will continue to grow thus they focus on the making biological areas for their protection, reserved forest and protected forest areas are solely created so that the species get their chances to survive.
