Consider the following statements:
1. The energy flow in an ecosystem results in entropy.
2. In prairie ecosystem, `90%` of the secondary productivity occurs in the soil.
3. The detritus chain is of greater importance in energy flow in many ecosystem than are herbivorous/carnivorous/omnivorous grazing chains.
Which of these statements are correct?

Which of the following statements is not correct about energy flow in an ecosystem ?

Which of the following statements is not correct about energy flow in an ecosystem ?

Which of the following statements about food chains and energy flow through ecosystem is false?

Give scientific reasons for the following statements : Energy flow is always unidirectional in an ecosystem.

Mention briefly the factors of energy flow in ecosystem. Give an example of detritus food chain.

Correct and write the following statements and justify your corrections: The flow of nutrients in an ecosystem is considered to be a one way transport.

Which of the following statement(s) regarding energy flow is/are false? I. The detritus food chain begins with dead organic matter. II. In aquatic ecosystem, detritus food chain is the major conduit for energy flow. III. In terrestrial ecosystem a larger fraction of energy flows through grazing food chain. IV. Producers belong to the first trophic level of the food chain.
