Question

1. energy transfer & trophic levels

only about % of energy is transferred to the next trophic level.
most energy is or lost as.
order the trophic levels from most to least energy: 1. 2.

1. 4.

Explanation:

In the context of energy transfer in ecosystems (a topic in Biology, a subfield of Natural Science), the 10% rule states that only about 10% of energy is transferred to the next trophic level. Most energy is used for metabolic processes (like respiration) or lost as heat. Trophic levels, from most to least energy, are producers (they capture energy from the sun), primary consumers (eat producers), secondary consumers (eat primary consumers), and tertiary consumers (eat secondary consumers), as energy decreases with each transfer.

Answer:

Only about $\boldsymbol{10}$% of energy is transferred to the next trophic level.
Most energy is $\boldsymbol{used\ for\ metabolic\ processes}$ or lost as $\boldsymbol{heat}$.
Order the trophic levels from MOST to LEAST energy: 1. $\boldsymbol{Producers}$ 2. $\boldsymbol{Primary\ Consumers}$ 3. $\boldsymbol{Secondary\ Consumers}$ 4. $\boldsymbol{Tertiary\ Consumers}$
