A food chain shows a single connected path of energy flow through an ecosystem. It shows the different levels of eating in an ecosystem. Both a good web and a good chain include a number of organisms including both producers and consumers. A food chain is very simple while a food web is complex and consists of a number of food chains. In a food chain each organism has only one consumer or producer.

Question 8 How would you describe the effect of different magnitudes of the same factor on the number
Ghella [55]

Answer:

Let's start off with an example. Imagine a population of organisms—let's say, deer—with access to a fixed, constant amount of food. When the population is small, the limited amount of food will be plenty for everyone. But, when the population gets large enough, the limited amount of food may no longer be sufficient, leading to competition among the deer. Because of the competition, some deer may die of starvation or fail to have offspring, decreasing the per capita—per individual—growth rate and causing population size to plateau or shrink.
