If an organism is stationary what is the purpose of having a motile phase at some point in the life cycle?

Answer/Explanation:

Stationary organisms generally do not move by self locomotion.They could move through the actions of external forces such as moving water but cannot move alone.

Most stationary organisms (also called sessile organisms) have a motile phase in their life cycle. This allows them do disperse across longer distances. This is important for the survival of the species, as it means they can exploit a larger food supply and other resources.

european union policies. the eu's long-term objective is to achieve levels of air quality that do not result in unacceptable impacts on, and risks to, human health and the environment. eu policies aim to reduce exposure to air pollution by reducing emissions and setting limits and target values for air quality.

the main environmental problems in western europe were: energy production/acid rain, nuclear power/waste, air pollution/climate, heavy metals, pesticides, water pollution, solid waste, and unforeseen accidents. many environmental problems are common to most european countries.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
