Question

What is adaptation of plants and animals living in aquatic habitat?

Answer 1

Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes. These plants require special adaptations for living submerged in water, or at the waters surface. The most common adaptation is aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is permanently saturated with water.

They are therefore a common component of wetlands. An aquatic animal is an animal, either vertebrate or invertebrate, which lives in water for most or all of its life. Many insects such as mosquitoes, mayflies, dragonflies and caddisflies have aquatic larvae, with winged adults. Aquatic animals may breathe air or extract oxygen from that dissolved in water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land).

Answer 2

Explanation:

• The term hydrophytes or macrophytes is also used to describe plants that live in water.
• Dissected leaves and floating plants are two examples of aquatic plants' adaptations. Aquatic animals have gills for respiration, fins and tails for propulsion, and streamlined bodies for easier swimming.
• Aerenchyma, a lightweight interior packing cell, is the most frequent adaption, but floating leaves and finely divided leaves are also frequent.
• Only in water or in soil that is frequently drenched with water may aquatic plants flourish. Therefore, they are a typical part of wetlands.

An aquatic vertebrate must be able to endure:

• Forces of gravity in order to exist on land.
• Air breathing is a must.
• Should reduce water loss (desiccation).
• It must modify its senses to make them appropriate for air as opposed to water.
