AveGali [126]

Answer:

a. Approximately 1,003 weasels, 3,345 mice and 16,729 wheat plants per one hawk are in the ecosystem

Explanation:

The percentage of the weasel population eaten by a hawk = 30%

The percentage of the mouse population eaten by a weasel = 30%

The percentage of the wheat plants population eaten by a mice = 20%

a. One hawk needs 330 kJ of energy per day, which gives 330 kJ × 365 = 120,450 kJ per year

Let 'x' represent the number of weasels to support one hawk, we have;

0.3 × x = 120,450 kJ/year/(400 kJ) = 301.125

x = 301.125/0.3 = 1,003.75

The number of weasels required to support one hawk per year ≈ 1,003 weasels

The total weasels ≈ 1,003

ii) The number of mice needed, y = x/0.3 = 1,003.75/0.3 = 3,345.8\overline 3

The total mice, y ≈ 3,345 mice

iii) The number of wheat flower needed, z = y/0.2

∴ The number of wheat flower needed, z = 3,345.8\overline 3/0.2 ≈ 16,729.1\overline 6

The total wheat plants ≈ 16,729.

Match the rocks with the material they are made of. igneous rocks /sedimentary rocks /metamorphic rocks
Vlad1618 [11]

The answers would be:

Igneous Rocks - They are made from hot magma.

Sedimentary Rocks - They are made from weathered pieces of rock.

Metamorphic Rocks - They are rocks, small or large which reformed due to high temperature.

If you'd like to know more, read on:

Igneous rocks are formed when hot magma is cooled and then it hardens into a rock. The word igneous comes from the word, "ignis" which means "of fire. They can be formed beneath the Earth or on the surface.

Sedimentary rocks are formed from weathered pieces of rock. These pieces are called <u>sediments</u>. They can also be made out of other material. When these sediments settle, it continues to do so until so much sediment accumulate and they start to press down on each other. The sediments then start to go through compaction and sedimentation which for a sedimentary rock.

Metamorphic rocks form under heat and pressure. They are squeezed and shaped and go through <u>metamorphosis </u>or go through change. A metamorphic rock can be formed from any other type of rock as long as it goes through changes due to intense pressure and/or heat.
