Pioneer species such as lichen and moss inhabit an area after a major disturbance such as a volcanic eruption. Over time, other species are found in the disturbed area and the number of pioneer species decreases. Why does the number of pioneer species decrease?:quizzes

The correct answer is - The area has more soil to support complex plants. The competition decreases the pioneer species role.

Explanation:

Pioneer species are the initial species of organisms such as lichens and moss. These species appears in disturbed land where they break the rocks and at that time of their introduction to the area, there is enough amount of nutrition for their growth and survival.

After establishing the complex plant species these pioneer species are decreased due to the competition for the resources but due to enough soil and complex structure of the new plant species, they get very few minerals and other nutrition.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

the answer is c.
