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.

Glycolysis requires an input of energy. What molecule provides this energy?
shusha [124]

Answer:

Glycolysis is actually a series of ten chemical reactions that requires the input of two ATP molecules. This input is used to generate four new ATP molecules, which means that glycolysis results in a net of two ATPs.

Lichens are composed of two organisms, a fungus
algol [13]

Answer:

B) ecological succession

Explanation:

The analogy given in this question describes ECOLOGICAL SUCCESSION, which is the series of changes that an ecosystem undergoes over a period of time. Ecological succession is of two types viz: Primary succession and Secondary succession.

Primary succession involves the series of changes that occurs on a new habitat that has never been previously colonized. This is the case of the colonization of bare rocks with no plant life by LICHENS. The action of the lichen, which involves secretion of acids that disintegrates the rocks into soil, paves way for the colonization of that area by new species.

Lichens, via the role they play in primary succession by helping alter a barren area into a fertile one that accommodates other organisms, makes them be regarded as PIONEERS of primary succession.
