In which of the following populations is the MOST energy concentrated (Answer fast)

A. Boreal owl
B. Limber pine
C. Canada lynx
D. Snowshoe hare

B. Limber pine

Explanation:

Going up the trophic levels, the energy is most concentrated in the lowest level. As it goes up, the amount of energy obtained through the consumption of those below is only 10% of the previous. So producers get the most energy, directly from the sun. (ex. 1000kcal) When the primary consumers eat them, they get only 10% of that energy obtained from the sun (which will be 10% of 1000).

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
