Adapting to survive Adaptation: The process helps living organisms to survive in the environment where they live. Habitat: the area where the living organism lives Types of adaptation Structural (physical) behavioral adaptation adaptation Adaptation related to the body Change in the behaviors or acts of structure of living organism. living organism.

Genetic factors: are inherited traits transfer from the parents to offspring. Miss.

Miss. Kholoud Ahmed 01158479276  Plants in desert ex: cactus, palm, opuntia  they have short extended root; to absorb any available water.  Long roots; to absorb the ground water.  Thick leaves and stem; to store water.  Thorns; to keep away herbivores. Desert Is the most extreme environment on the earth. It may be hot or cold. Antarctica is a cold desert Genetic factor (inherited traits) helps the plants in desert to survive in extreme hot weather and little rainfall and become stronger than their parents. Miss. Kholoud Ahmed 01158479276 Gene Tiny structure inside the cell nucleus of the living organisms body that carries the inherited traits. Transfer from the parent to offspring. Ecosystem: Area of land contains biotic and abiotic factors interact with each other. Biotic factors Abiotic factors Living organisms Non-living things Such as: plants - animals Such as: air-water-light-soil Arctic ecosystem Caribou feeds on grasses and the wolves hunt the caribou. Miss. Kholoud Ahmed 01158479276  The abiotic factors affect the growth of biotic factors Ex: the intensity and amount(quantity) of light effect on the plant. Duration of light: is the amount of time the plant exposed to the light Some plants grow and produce fruits when the day is longer than the night. Some other plants produce flowers when the day is shorter than the night. Such as: chrysanthemum plant If light is too intense, it may cause burning and drying the plant. Inherited traits (genetic factor) Offspring inherit the appearance from their parents. sphynx cat Birman cat doesnot have long silky colored hair hair Miss.
