slega [8]

Answer:

Option D, only II, III, and IV

Explanation:

Complete Question

Ecosystem services include processes that increase the quality of the abiotic environment. Which of the following processes would fall under this category?

I) Keystone predators have a marked effect on species diversity.

II) Green plants produce the oxygen we breathe.

III) The presence of land plants builds soil.

IV) The presence of diverse wetlands helps in flood control.

A) only II and IV

B) only I and III

C) only I, II, and IV

D) only II, III, and IV

Solution -

The services of ecosystem has been classified into four groups

a) Provisioning – Where essential abiotic and biotic substance are produces such as production of food and water, reproducing offspring etc.

b) Regulating – the ecosystems is controlled through environmental factors such as control of climate and disease

c) Supporting – Ecosystem support the activities that are essential for survival. Primarily includes all nutrient cycles, oxygen generation etc.

d) Cultural – Provide aesthetic view and recreational benefits

Option II co mes under supporting service of ecosystem

Option III co mes under Provisioning service of ecosystem

Option IV co mes under Regulating service of ecosystem

Hence, option D is correct

scientists believe the earth likely warmed between 0.65 celsius and 1.05 celsius with an average value of 0.85 celsius between y

scoray [572]

Answer:

The lower limit is 0.65°C

The upper limit is 1.05°C

the average is 0.85°C

The difference between the average and the lower limit is:

0.85°C - 0.65°C = 0.20°C

the difference between th average and the upper limit is:

0.85°C - 1.05°C = -0.20°C

Then we can write the change in temperature as:

T = 0.85°C ± 0.20°C

Now we want to find the error bar.

The error bar would be the total distance between the lowest value and the largest value.

Then the error bar is:

1.05°C - 0.65°C = 0.40°C

notice that the error bar is twice the error, which makes a lot of sense because the error (± 0.20°C) goes up and down.

Then the error bar in this measure has a magnitude of 0.40°C.
