Brainliest! (as always) which of these examples describes a structure penguins use for movement?
question 9 options:

a penguin stands with a group of other penguins when a predator approaches.

a penguin holds an egg under its feathers to keep it warm

a penguin uses sleek, smooth belly feathers to slide on ice

a penguin holds a squid in its bill.

It is the third option. Reason being is because the first one describes what they do when danger approaches and it doesn't say anything about moving. The second one describes what they do to protect their young from the harsh environment around them; no movements mentioned. The fourth one just says what a penguin does but they can be standing when they do it; no mention of any movements at all.

Hope this helps!! :)

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

idk im sorry.
