Question

1. this series of changes in the area over hundreds of years is known as

a. evolution
c. nitrification
b. succession
d. decomposition

1. what is shown in diagram a above?

a. desert community
c. pioneer species
b. climax community
d. stable community

Explanation:

• For question 2, succession refers to the series of changes in an ecological community over time. Evolution is about genetic - based changes in species, nitrification is a part of the nitrogen cycle, and decomposition is the breakdown of organic matter.
• For question 3, pioneer species are the first species to colonize a new or disturbed area, which is often depicted as the starting point in succession diagrams like Diagram A. A desert community has specific arid - adapted species, a climax community is the final stable stage of succession, and a stable community implies a long - term equilibrium.

Answer:

1. b. Succession
2. c. Pioneer species
