BIOXII14: ECOSYSTEM

344523 To identify how many organisms are present at each trophic level, the pyramid is called

1 An energy flow pyramid
2 Pyramid of numbers
3 Pyramid of energy
4 Food chain/food web pyramid
BIOXII14: ECOSYSTEM

344524 Ascending trophic level in grazing food chain pyramid represents

1 Gradual decrease in biomass from base to the apex
2 No change in biomass
3 Gradual increase of the biomass from producers to the tertiary consumers
4 gradual decrease in biomass from apex to the base
BIOXII14: ECOSYSTEM

344525 Read the following statements and select the correct option
I. Producers constitute the first trophic level of a detritus food chain
II. Productivity of an aquatic system is less than that of a terrestrial system
III. A given species may occupy more than one trophic level in the same ecosystem at the same time

1 II and III
2 I and II
3 Only III
4 I and III
