What do you call the ability of an organism to respond to stimuli?
The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity (excitability).
What is the word for a change in the environment that a receptor cell response to?
A stimulus is a change in the internal or external environment. A receptor detects a stimulus. A coordinator formulates a suitable response to a stimulus.
How do organisms respond to changes in their environment?
The control systems that allow organisms to respond to changes are incredibly important. Cells called receptors , which detect stimuli (changes in the environment). The coordination centre, such as the brain, spinal cord or pancreas, which receives and processes information from receptors around the body.
When an organism changes and reacts to a stimulus that is the?
A change in an organism’s surroundings that causes the organism to react is called a stimulus (plural stimuli). An organism reacts to a stimulus with a response- an action or change in behavior. Another example is if you are cold, you shiver. The cold is the stimulus while the shivering is the response.
Which is reaction of organism stimulus to?
> Here’s your answer : The reaction of an organism to a stimulus is called a response to stimuli.
Which process refers to the ability of organism in acquiring food?
Explanation: Autotrophic organisms make their own food by a process called photosynthesis. Green plants, for example, manufacture sugar and starch from carbon dioxide and water using the energy of sunlight to drive the necessary chemical reactions.
How do organisms interact with and respond to changes in their environment?
In all these environments, organisms interact and use available resources, such as food, space, light, heat, water, air, and shelter. Each population of organisms, and the individuals within it, interact in specific ways that are limited by and can benefit from other organisms.
What are the sensory receptors?
Sensory receptors are specialized epidermal cells that respond to environmental stimuli and consist of structural and support cells that produce the outward form of the receptor, and the internal neural dendrites that respond to specific stimuli.
How do organisms maintain a stable internal environment?
Living Things Maintain Stable Internal Conditions When any living organism gets thrown off balance, its body or cells help it return to normal. Maintaining a balance inside the body or cells of organisms is known as homeostasis. Like us, many animals have evolved behaviors that control their internal temperature.
How does an animal’s response to environmental stimuli help them survive and reproduce?
Animals may respond to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather (stimulus) some animals will hibernate. The animal’s body temperature drops, its heartbeat and breathing slow down, and it uses very little energy.
What is a change in an organism’s environment that causes the organism to react is called?
A change in an organism’s surroundings that causes the organism to. react is called a stimulus. An external stimulus comes from outside the organism, while an internal stimulus comes from inside the organism. An organism reacts to a stimulus with a response an action or change in behavior.
What is the process of change that occurs during an organism’s life to produce a more complex organism?
Growth is the process of becoming larger. Development is the process of change that occurs during an organism’s life to produce a more complex organism.
