The roles and relationships that exist amongst the producers, consumers, and decomposers in an ecosystem is described by the food chain.

The meaning of ecosystem is the complex of a community of organisms and its environment functioning as an ecological unit.

Producer is an organism that produces its own food e.g. photosynthesis in plants. Also known as the base of the food-chain.

Consumer is an organism that consumes (eats) either a producer or another consumer e.g. animals will solely eat plants (herbivore), solely animals (carnivore), or a combination of both (omnivore).

Studies are showing that most animals are omnivores. Even pre-concluded herbivores or carnivores are found to eat a small variety of both plants and animals in a pinch. E.g. a deer would eat a baby bird if it found it on the ground.

Decomposers are organisms that 'eat' and break up dying/decaying material e.g. earthworms and fungi.

All of this together is the food cycle.

Answer:

61/10 or in decimal form 6.1 or 6 1/10

Step-by-step explanation:

Answer:

166.3

Step-by-step explanation:

line that shows 8, shows that each of six sides is 8

so that's 48

to get the "apothem"

it means get a side of the triangle where the hypotenuse is 8 and the base is 4 (half of 8)

so that is square root of 48 which is like 6.928

then plug into the formula

1/2 x 6.928 x 48 which is like 166.27

Answer:

13

Step-by-step explanation:

You need to use pythagorean theorem (a^2 + b^2 = c^2). In this case 5 is a, 12 is b, and z is c. 5^2 + 12^2 = z^2, this ends up as 169 = z^2. Now you find the square root of 169 which is 13.

Step-by-step explanation:

Maybe it is root 5²time 12²=60

Answer:

(d)

Step-by-step explanation:

Given

See attachment for [tex]\triangle BCD[/tex] and [tex]\triangle B"C"D"[/tex]

Required

The transformations

Using B and B"" as points of reference, we have:

[tex]B = (1,4)[/tex]

[tex]B"" = (5,-1)[/tex]

The transformation is as follows:

First, reflect across y axis.

The rule is:

[tex](x,y) \to (-x,y)[/tex]

So, we have:

[tex]B(1,4) \to B'(-1,4)[/tex]

Next, translate 6 units right.

The rule is:

[tex](x,y) \to (x + 6,y)[/tex]

So, we have:

[tex]B' (-1,4) \to B"(-1 + 6,4)[/tex]

[tex]B' (-1,4) \to B"(5,4)[/tex]

Lastly, translate 5 units down

The rule is:

[tex](x,y) \to (x,y-5)[/tex]

So, we have:

[tex]B"(5,4) \to (5,4-5)[/tex]

[tex]B"(5,4) \to (5,-1)[/tex]

Answer:

[tex](c)\ 9 - (3 * 2) \div 3 + 6[/tex]

Step-by-step explanation:

Given

(a) to (d)

Required

Which equals 13

[tex](a):\ 9 + 3 * (2 \div 3) + 6[/tex]

Solve the bracket

[tex]9 + 3 * (2 \div 3) + 6 =9 + 3 * (\frac{2}{3}) + 6[/tex]

Open the bracket

[tex]9 + 3 * (2 \div 3) + 6 =9 +2 + 6[/tex]

[tex]9 + 3 * (2 \div 3) + 6 == 17[/tex]

[tex](b):\ (9 + 3) * 2 \div 3 + 6[/tex]

Solve the bracket

[tex](9 + 3) * 2 \div 3 + 6 =(12) * 2 \div 3 + 6[/tex]

Open bracket

[tex](9 + 3) * 2 \div 3 + 6 =24 \div 3 + 6[/tex]

Divide

[tex](9 + 3) * 2 \div 3 + 6 =8 + 6[/tex]

[tex](9 + 3) * 2 \div 3 + 6 =14[/tex]

[tex](c)\ 9 - (3 * 2) \div 3 + 6[/tex]

Solve the bracket

[tex]9 - (3 * 2) \div 3 + 6 =9 - (6) \div 3 + 6[/tex]

Remove bracket

[tex]9 - (3 * 2) \div 3 + 6 =9 - 6 \div 3 + 6[/tex]

Divide

[tex]9 - (3 * 2) \div 3 + 6 =9 - 2 + 6[/tex]

[tex]9 - (3 * 2) \div 3 + 6 =13[/tex]

[tex](d)\ (9 + 3 * 2) \div 3 + 6[/tex]

Solve the bracket (the product, first)

[tex](9 + 3 * 2) \div 3 + 6=(9 + 6) \div 3 + 6[/tex]

[tex](9 + 3 * 2) \div 3 + 6=15 \div 3 + 6[/tex]

Divide

[tex](9 + 3 * 2) \div 3 + 6=5 + 6[/tex]

[tex](9 + 3 * 2) \div 3 + 6=11[/tex]

Only (c) equals 13

Step-by-step explanation:

Hi

Answer:

the amount paid by Sarah is $20.64

Step-by-step explanation:

Given that

The total cost of the dinner is $61.92

And her friends pay 2 by 3

We need to find out the amount paid by Sarah

Since her friends pay 2 by 3 of the total cost

That means the remaining should be paid by Sarah i.e. 1 by 3

So, we need to multiply 1 by 3 with the total cost of the dinner i.e.

= 1 ÷3 × $61.92

= $20.64

Hence, the amount paid by Sarah is $20.64

hello :

d. No solution

Let the two whole numbers be 2x and 5x

The difference between 2x and 5x is 99. So,

5x-2x=99

3x=99

x=99/3

x=33

Therefore the two numbers are

5x=5*33=165

2x=2*33=66

Answer:

28:71

Step-by-step explanation:

99/7=14.14285714 (make sure to keep that in the calculator) that equals 1 part.

Therefore,

5×14.14..=71 (round up to nearest whole number)

Imagine this < as a alligater and itś eating the greater number!!

Answer:

C.) r ≥ 7

Step-by-step explanation:

1. Add 7 to each side to cancel it out and keep the sign the way it is to avoid confusion

3r - 7 ≥ 14

   + 7    +7

3r ≥ 21

2. Divide each side by 3 to get the variable alone

3r/3 = r

21/3 = 7

r ≥ 7

This means r is greater than or equal to 7, and it can also be written as 7 ≤ r

Answer:

1.66$ per liter

Step-by-step explanation:

Hi there! I hope you're having a good day so far. :)

So this equation is quite simple. To write it out, you get:

35/21.00=?

All you need to do is get a calculator and put that in.

Then you will get 1.66666667, but to 'simplify' it, you just get 1.66 dollars per liter.

Therefore, the answer is 1.66$ per liter.

Answer:

Step-by-step explanation:

ah,  probability,  so the std. deviation is 2 MPH,  so that means to get from the mean.. or average speed of 94, he'll have to vary by 3 std. deviations  or  6 MPH to hit 100

99.7%  of throws fall into that area of with in 3 std. deviations so that means

0.3% fall outside also , 1/2 of those will 3 std. deviations slow while the other half is fast

so

0.15%  will be 100 or faster.... not many

0.15% is the percent of Kershaw’s fastballs will travel at least 100 mph.

A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

The standard deviation is 2 MPH,  so that means to get from the mean.. or average speed of 94, he'll have to vary by 3 standard deviations  or  6 MPH to hit 100

99.7%  of throws fall into that area of with in 3 standard deviations  so that means

0.3% fall outside also , 1/2 of those will 3 standard deviations slow while the other half is fast

so 0.15%  will be 100 or faster
