Study Notes
Living Organisms - Characteristics and Habitats
- A habitat is a natural place for an organism to live, survive, breed, and flourish.
- Biotic components are all living components of a habitat (e.g., plants, animals, microorganisms).
- Abiotic components are all nonliving components of a habitat (e.g., soil, water, air, sunlight).
- Adaptation is a feature developed in an organism to survive in a particular environment.
- Nocturnal animals are active during the night.
- Hibernation is a long winter sleep of some organisms.
- Xerophytes are desert plants.
- Succulent plants store water in their spongy stems.
- Hydrophytes are aquatic plants of fresh water.
Types of Habitats
- Terrestrial habitats are land habitats, including forests, mountains, grasslands, deserts, and coastal regions.
- Aquatic habitats are water habitats, including seas, lakes, rivers, and ponds.
- Aerial or arboreal habitats are air or tree habitats, such as tropical forests.
Components of Habitats
- Biotic components are all living things: humans, animals, plants, and microorganisms. They are the living component.
- Abiotic components are non-living things like soil, water, atmosphere, and meteorological factors (sunlight, temperature, rainfall, wind). They are the non-living component.
Adaptations in Different Habitats
- Organisms adapt to specific features of their environment.
- Adaptations are typically specific features that help improve the chances of survival in a particular environment.
- Permanent adaptations have a genetic basis and cause permanent changes.
- Temporary adaptations are short-term adaptations that are not inherited.
- Examples include camel adaptations to arid regions or birds adapted to live in cages.
Adaptation to Desert Habitats
- Desert climates are hot and dry with little vegetation.
- Many desert animals are inactive during the day and active at night (nocturnal).
- Certain animals hibernate for part of the year
- Adaptations include physical changes to extremities (e.g., large pads for movement across hot sand and fat reservoirs in the humps of camels). These adaptations are specific to the desert environment.
- They store or retain water
Adaptation to Mountaineous Regions
- Mountainous regions are typically cold and windy.
- Mountain plants include cone-shaped trees with sloping branches and needle-like leaves; these adaptations help rainwater and snow slide off easily.
Adaptation to Grasslands
- Grasslands have plenty of grass.
- Herbivores in grasslands have strong teeth for chewing grass, long ears for tracking predators, and long legs for running.
- Carnivores (meat-eating animals) living in grasslands have sharp claws, eyes in front of their face, and long strong canines for catching and killing prey.
Adaptation to Aquatic Habitats
- Aquatic habitats include fresh and saltwater habitats.
- Aquatic animals have streamlined bodies and adaptations such as gills, fins, or flippers to aid in movement and breathing.
- Aquatic plants have hollow stems or air spaces to keep them afloat.
Living Beings - General Characteristics
- Need food for energy and to grow
- Breathe in air (or oxygen dissolved in water in aquatic organisms). This process is called respiration
- Excrete waste products; this process is called excretion.
- Respond to stimuli from the environment (e.g., temperature, touch, light, sound); this is a response to stimuli.
- Reproduce producing their own kind.
- Grow and develop over time.
- Have a life span—a period of time from birth to death.
- Are made up of cells (the smallest structural and functional units of a living being).
