LifeLine

An adaptation is a characteristic which helps an organism to survive in its environment. Plants and animals must adapt so they can compete for resources and live successfully in their habitat. Some adaptations can help organisms to not get eaten, hide, control body temperature or prevent water loss. An adaptation gives an organism a better chance of surviving in its environment. 

Importance of adaptation is vital for species survival. Every organism must adapt to its environment. Adaptation allows organisms to survive in specific, sometimes even harsh, climate. 

Types

Structural

• physical features of the body
• example
  • having fins for aquatic animals who need to swim  efficiently
  • Having camouflage that helps you blend  in with your environment
  • have brightly coloured flowers which attracts  insects 

Behavioral

• ways a particular organism behaves (mainly born with the ability)
• example
  • herding helps in getting food and spotting predators
  • hibernation or aestivation

Physiological

• mechanisms present
• process inside the organism
• example
  • snake’s ability to produce venom
  • mammal’s ability to maintain constant body temperature

Extremophiles

• Microorganisms like bacteria or archaea that are adapted to live in extreme environments
• Example:
  • Thermophiles
    • really high temperatures like in hot springs 
    • feed off of inorganic chemicals and have special enzymes to survive high temperatures
• Understanding the limits of life in these extreme conditions on Earth may provide scientists with clues of how life could possibly exist elsewhere in the universe.

Adaptation Examples

Camels 

Functional – They have a hump which stores fat, this helps in thermoregulation and helps with heat loss more easily. The concentrated fat helps in evaporating the sweat easily around the body surface. 

Structural – They have wide feets, to prevent them from sinking in the sand. They have eyelashes and thin nostrils to stop sand getting blown into them.

Behavioral – The spit as a reaction to a threat. They have compartments in the stomach in which grassy, tough food is fermented and broken down by special bacteria.

Ostrich 

Functional – They have long legs with strong muscles and thick bones to run fast at 43 miles per hour.

Structural – Flightless wings, a long neck, camouflage, and a decreased need for liquid water.

Behavioral – They bury their heads in the sand to keep from being seen and they dig holes to serve as nests for their eggs.

Adaptations of Plants In Deserts

Deserts are too dry and hot to imagine life in them. Despite these arid conditions, few plants have adapted to thrive here.

• Succulents are such plants which can store water in their modified stems and leaves
• The spines on cacti also help prevent excess water loss
• Some plants have long, deep roots which can absorb water from the ground
• Other plants grow short to save energy
• Another form of adaptation is dormancy, few seeds remain dormant until they get the water needed for growth

Adaptations are essential because environments are constantly changing. A species with the right traits can survive challenges like predators, extreme weather, or food shortages. Without adaptations, life wouldn’t have the incredible diversity we see today. It showcases how life finds a way to thrive even in the harshest conditions.
