TPO 33 - Question 4
A sample Answer to this speaking in text:
The greatest number of animals a habitat can support is called carrying capacity. Carrying capacity is not fixed. It changes according to the environment. The professor uses the relationship of moth and ragwort to illustrate this concept. Moth is a kind of insect that eats ragwort. Ragwort is a plant that grows in the field. Normally, the number of moth in the ragwort field is stable. But if there were a lot less rain in a year, ragwort wouldn’t grow well. Moth wouldn’t survive and even those that survived lay fewer eggs. So the number of moth would decrease. But if the rain went back to a normal level, the ragwort would grow well. Moth would have enough to eat and would lay more eggs. And the number of moth would also increase.
