Ecosystem Productivity

Which of the following ecosystem types has the highest annual net primary productivity?

1. Tropical rainforest

2. Tropical deciduous forest

3. Temperate evergreen forest

4. Temperate deciduous forest

The biomass available for consumption by the herbivores and the decomposers is called:

1. net primary productivity

2. secondary productivity

3. standing crop

4. gross primary productivity

Secondary productivity is the rate of formation of new organic matter by:

1. Parasite

2. Consumer

3. Decomposer

4. Producer

Which ecosystem has the maximum biomass?

1. Grassland ecosystem

2. Pond ecosystem

3. Lake ecosystem

4. Forest ecosystem

In the equation GPP – R = NPP, R represents:
1. Environment factor
2. Respiration losses
3. Radiant energy
4. Retardation factor

In the equation 

GPP is Gross Primary Productivity. NPP is net Primary Productivity. R here is ___________
1. Reproductive allocation 
2. Photosynthetically active radiation 
3. Respiratory quotient 
4. Respiratory loss

In an ecosystem, if the Net Primary Productivity (NPP) of first trophic level is what would be the GPP (Gross Primary Productivity) of the third trophic level of the same ecosystem?

1.
2.
3.
4.

Given below are two statements:

Statement I:	The primary source of energy in an ecosystem is solar energy.

In the light of the above statements, choose the most appropriate answer from this options given below.

1.	Statement I is correct but statement II is incorrect
2.	Statement I is incorrect but statement II is correct
3.	Both statement I and statement II are correct
