Answer:
Option B, 2 percent
Explanation:
Complete question is
In a community, autotrophs generate 1,000 calories per hour of GPP and 500 calories per hour of NPP. Primary consumers convert 10 calories per hour into their own biomass. What is the ecological efficiency in the link between autotrophs and primary consumers in this community?
1 percent
2 percent
20 percent
10 percent
Solution
Given
Autotrophs generating calories per hour of GPP 
Autotrophs generating calories per hour of NPP 
The rate at which the primary consumers convert calories per hour into biomass is equal to
calories per hour
The ecological efficiency is equal to" the rate of calorie conversion to biomass" divided by the net produced calories multiplied by 
Rearranging the above relation in a mathematical equation, we get -

Hence, option B is correct

<span>Hi,
The food is chewed and grinned up from the teeth and broken down from saliva, then the epiglottis shuts covering the trachea allowing food to travel
down the esophagus, once it travels down it reaches the stomach which is mechanically and chemically broken down from the stomach muscles and the hydrochloric acid. Then it goes into small intestine, then the large intestine where it is determined to be a solid, liquid, or gas and the liquid is normally drained out causing it to be solid, Then it is eventually stored in the rectum and released through the anus. There are three helping organs the liver, gallbladder, and pancreas which produce the digestive enzymes but arent part of the digestive tract,
