Primary carnivores are, most aptly, characterized as:
1. | Secondary producers | 2. | Primary consumers |
3. | Secondary consumers | 4. | Tertiary consumers |
In a terrestrial ecosystem, a much larger fraction of energy flows through the:
1. | DFC | 2. | GFC |
3. | Either of DFC or GFC | 4. | Nither of DFC nor GFC |
In an aquatic food chain, zooplankton occupy which trophic level?
1. | First | 2. | Second |
3. | Third | 4. | Fourth |
Identify the incorrectly matched pair:
1. Carnivores -- secondary or tertiary consumer
2. Decomposers -- microbial heterotrophs
3. Herbivores -- primary consumer
4. Omnivores -- molds, yeasts and mushrooms
Each trophic level has a certain mass of living material at a particular time, best called as:
1. | Biomass | 2. | Standing state |
3. | Standing crop | 4. | Gross productivity |
Approximately, what percent of energy is transferred to each trophic level from the lower trophic level in an ecosystem?
1. | 1 | 2. | 10 |
3. | 50 | 4. | 90 |
