Energy flow and nutrient cycling are two important components of an ecosystem. What will be true comparison of the two?

The amount of nutrients present in the soil, at any given time, is referred to as:
1. Standing state
2. Standing crop
3. Primary productivity
4. Secondary productivity

The reservoir is located in the Earth’s crust for:
I. Gaseous type of nutrient cycle
II. Sedimentary nutrient cycle
1. Only I
2. Only II
3. Both I and II
4. Neither I nor II

The function of a reservoir of nutrient cycle is to:
1. synthesize minerals
2. transfer minerals to other ecosystems
3. meet any deficit
4. destroy the unwanted minerals

The maximum percent of total global carbon is found:
1. in fossil fuels
2. in atmosphere
3. dissolved in oceans
4. in biomass of microbes

Consider the given two statements:

An important feature of the phosphorus cycle is that its reservoir is in:
1. aquifers
2. soil and rocks
3. the atmosphere
4. the sun

Regarding phosphorus cycle:

1. Only I is true.
2. Only II is true.
3. Both I and II are true.
4. Both I and II are false.

If we put a price tag on nature’s life-support services, about 50 % of the total cost will be accounted for by:
1. Recreation and nutrient cycling
2. Soil formation
3. Climate regulation
4. Habitat for wildlife
