Document Summary
Carnivores: animals that kill and eat other animals. Herbivores: animals that prey on plants and algae: plants are usually damaged but not killed, not necessarily true for algae. Parasites: obtain their nutrition from other organisms, can harm that organism, but they don"t normally kill it. Parasitoids: insects, lay eggs on or near the host insect, which is subsequently killed and eaten by the developing parasitoid larvae. In medium oat with sediment (which constituted a refuge for paramecium, didinium starved and then paramecium emerged to increase in numbers: the mechanism to achieve stability was through immigration. One paramecium and one didinium every third day: gaude conclusion: that stable oscillations in this system are not the property of the predator prey interaction and it is in fact the result of interference from outside the system. Population cycles: such as gauss and huffaker produced, are also observed in nature.
