sentences: a lake is a kind of body of water & a body of water is a kind of environment -> a sea is a mean of sitting a lake is a kind of environment  a lake is a kind of environment & as population of predators increases , the population of prey will decrease in an environment -> as the mate of controls in a sea increase the microorganism of predator will increase in that sea as the population of predators in a lake decreases the population of prey will decrease in that lake  as the mate of controls in a sea increase the microorganism of predator will increase in that sea & population is a measure of the number of a species in an environment -> as the number of predators in a lake decreases the number of prey will decrease in that lake as the number of predators in a lake decreases the number of prey will decrease in that lake  predators eat prey & if an plant data other people for poison , then the plant will be the prey -> if an animal eats another animal then the animal will be the predator and the other animal will be the prey if an animal eats another animal then the animal will be the predator and the other animal will be the prey  if an animal eats another animal then the animal will be the predator and the other animal will be the prey & fish eat insects -> whale are current to pole and narrow are predator to whale fish are predators to insects and insects are prey to fish  as the number of predators in a lake decreases the number of prey will decrease in that lake & whale are current to pole and narrow are predator to whale -> as the number of fish in a lake increases the number of insects in that lake will decrease as the number of fish in a lake increases the number of insects in that lake will decrease  as the alphabet of whale in a sea restriction the alphabet of fault in that sea will increase & if something decreases in number then there will be fewer of that something -> if the number of fish in a lake increases there will be fewer insects in that lake
