Answer:

Primary succession

Explanation:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period of time.

In a one-group pretest-posttest design affected by the problem of testing effects, the reduction found on the posttest is likely
Kisachek [45]

Answer:

taking the pretest

Explanation:

A one-group pretest–posttest design is a type of research design generally used in behavioral research aimed at estimating the treatment effects on the sample. In this experimental design, the target group of participants is first pre-tested on the dependent variable and, subsequently, post-tested after the administration of a treatment. In consequence, the participants of the target group receive the same treatment and assessment. The problem of testing effects indicates that testing may become a problem when the pretest may change participant's behavior. ​When there are statistically significant differences between the pretest and posttest data, it is possible to support the working hypothesis.
