Question

What is the best reason why marine organisms require fewer adaptations to live in the low tide zone than in the other zones?.

Answer 1

The best reason why marine organisms require fewer adaptation to live in the low tide zone than in the other zones is the ability to retain moisture and burrow into the sand.

Adaptation: -

Adaptation is the process in which living organisms develop trait or features which will help them to adapt, survive and reproduce in their environment, passing the trait from one generation to another.

Types of Adaptation

Adaptations can be of the following types:

1. Structural Adaptations:

These involve the physical features of an organism that help them to survive in the environment including the different types of  terrestrial habitat. The physical changes are related to the changes in the physical environment. For eg., camouflage, which is the protective coloration that helps an organism to blend in its environment. This protects them from predators and increases their chances of survival.

2. Behavioral Adaptations:

This is the change that affects the behavior of an organism. This could be caused due to the changes in the surrounding environment or due to the actions of other species. For eg: The rabbit freezes if it feels that it has been seen by a predator. Changes in reproductive strategy, feeding habits, migration, hibernation, communication methods are a few other examples of behavioral adaptations.

3. Physiological Adaptations:

Like structural adaptations, the physiological adaptations also involve physical changes in the species. However, physiological adaptations are not always seen in the organism’s appearance. This type of adaptation can be either due to changes in the environment or due to the behavior of other species. For eg: A fish living in water that suddenly becomes more acidic has to shift its body chemistry to adapt itself.

Adaptation is essential for the survival of living organisms. Animals, which are unable to adapt to changing environmental changes die. These adaptations are a result of genetic changes. The animals that survive pass on the mutated genes to their offspring's. This is known as natural selection. Therefore, The types of adaptations would help organisms living in the high intertidal zone of a sandy beach survive is The ability to retain moisture and burrow into the sand.
