1 (e.a.) Biotic and Abiotic
An organism (and each of its cells) must breathe, grow, reproduce, use energy and responds to stimuli. Like a plant bending toward the light, the cells of the stem tissue are responding to the light. The light is the stimulus. All organisms react to changes in their environment. A change in an organism’s surroundings that causes the organism to react is called a stimulus (plural stimuli).
An organism responds to both the living and nonliving parts of its habitat. The living parts of a habitat are called biotic factors (by aht ik). Abiotic factors (ay by aht ik) are the nonliving parts of an organism’s habitat. They include water, sunlight, oxygen, temperature, and soil.
All organism reproduce through either sexual or asexual reproduction. Single celled organisms like bacteria reproduce asexually. Asexual reproduction involves only one parent and produces offspring that are identical to the parent. Sexual reproduction involves two parents who combine their genetic material to produce a new organism, which differs from both parents.
