One mouse eats 1 kg of plant food. Lynxes can eat 2% of the mouse population (an average of 800 rodents per year each). How many lynxes can survive in a community with a phytomass of 8000 tons if mice consume 1% of their phytomass and are the main food for lynxes?
1) Calculate the amount of phytomass that rodents eat: 8000 t – 100% xm – 1%
x = 80 tons (80,000 kg) of plants.
2) Since one mouse eats 1 kg of plant food, the number of mice is equal to 80,000 individuals. Let’s calculate how many mice the lynx eat:
80,000 – 100%
x = 1600 individuals.
3) If one lynx eats 800 rodents per year, then two lynxes can survive in this community (1600: 800 = 2).
Answer: 2 trot.
