the answer is <u>C</u>, because if you add the integers together, it equals four
Answer: 10% is the correct option.
Explanation:
when energy is passed in an ecosystem from one food chain level to the next, only ten percent of the energy will be passed on.
The amount of energy at each food chain level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any food chain level is transferred to the next level, the rest is lost largely through metabolic processes as heat.
Answer: Producers is the base of a food web.
Explanation:
At the base of the food chain lie the primary producers. The primary producers are autotrophs and are photosynthetic organisms such as plants, algae, etc.
0.808 km, you find the difference between the two numbers
Final list of friends = 10
Possible number of friends who can sit close to the head table = 6
This is a question of the number of combinations in choosing 6 friends from the list of 10 friends.
That is,
Number of ways = 10C6 = (10!)/[6!*(10-6)!] = 3628800/(720*24) = 210 ways.
Solve both equations for y:
Set the expressions equal to each other:
So, for every nonzero number a the system of equations has
one solution.
