Concept explainers
To determine: The kind of bottom features that might be involved to influence the settlement and metamorphosis of planktonic larvae.
Introduction: Metamorphosis is the process of development of an organism after the birth. This process involves the change in the structure of the animal body through cell growth and differentiation. Metamorphosis is the process that extends from an egg stage to the adult stage. The complete metamorphosis occurs in four stages including egg, larva, pupa, and adult.
Explanation of Solution
Metamorphosis is triggered by several physical, chemical, and biological factors.
The factors (physical, chemical, and biological factors) that influence the settlement and metamorphosis of planktonic larvae are given as follows:
- General type of bottom (rock, mud, sand).
- Size of particles (if mud or sand).
- Tridimensional part of rocky bottom (presence of crevices).
- Amount of dissolved oxygen in between sediment particles.
- Presence of hydrogen sulfide.
- Chemical composition of the substrate.
- Water temperature.
- Salinity.
- Currents.
- Sunlight.
