It can be internal (inside the body) or external (outside the body).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Types of Stimuli:<\/strong>\n<ul class=\"wp-block-list\">\n<li>External stimuli: These come from the outside environment, such as light, sound, temperature, or touch.<\/li>\n\n\n\n<li>Internal stimuli: These originate within an organism, like hunger, pain, or thirst.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Sensory Organs:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Living organisms have specialized sensory organs to detect different types of stimuli. For example, eyes detect light, ears detect sound, and skin detects touch.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Response to Stimulus:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Organisms respond to stimuli to survive and adapt to their environment.<\/li>\n\n\n\n<li>A response can be a physical or behavioral change. For instance, moving away from a painful stimulus like a hot object.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Nervous System:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Many animals have a nervous system that plays a crucial role in detecting and responding to stimuli. It includes the brain, spinal cord, and nerves.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Reflexes:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Reflexes are rapid, involuntary responses to a stimulus. They help protect the body from harm without conscious thought. For example, the knee-jerk reflex when a doctor taps your knee with a hammer.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Types of Responses:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Positive response: An organism moves towards a stimulus that benefits it, like reaching for food when hungry.<\/li>\n\n\n\n<li>Negative response: An organism moves away from a stimulus that harms it, like running from a predator.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Adaptations:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Over time, organisms can adapt to their environment by developing responses to specific stimuli. This is a key aspect of evolution.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Tropism:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Plants also respond to stimuli through a process called tropism. For example, phototropism is when a plant grows towards light.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Instinct and Learning:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Some responses are instinctual, meaning they are hardwired into an organism&#8217;s genetics. Others are learned through experience.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Habituation and Sensitization:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Habituation is when an organism becomes less responsive to a repeated stimulus that has no negative or positive consequences.<\/li>\n\n\n\n<li>Sensitization is the opposite, where an organism becomes more responsive to a repeated or intensified stimulus.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>In summary:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Organisms respond to stimuli through specialized sensory organs and their nervous systems.<\/li>\n\n\n\n<li>Responses can be voluntary or involuntary, and they help organisms survive and adapt to their surroundings.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<p class=\"has-text-color has-large-font-size\" style=\"color:#d90000\">Let&#8217;s practice!<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/wordwall.net\/play\/82399\/107\/117\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-78.png\" alt=\"\" class=\"wp-image-5066\" srcset=\"https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-78.png 500w, https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-78-300x300.png 300w, https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-78-150x150.png 150w, https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-78-400x400.png 400w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/wordwall.net\/play\/81815\/955\/144\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-76.png\" alt=\"\" class=\"wp-image-5067\" srcset=\"https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-76.png 500w, https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-76-300x300.png 300w, https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-76-150x150.png 150w, https:\/\/6thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-76-400x400.png 400w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/figure>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Response to stimulus Key Notes : Let&#8217;s practice!<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"om_disable_all_campaigns":false,"_mi_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"class_list":["post-4473","page","type-page","status-publish","hentry","entry"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/6thclass.deltapublications.in\/index.php\/wp-json\/wp\/v2\/pages\/4473","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/6thclass.deltapublications.in\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/6thclass.deltapublications.in\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/6thclass.deltapublications.in\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/6thclass.deltapublications.in\/index.php\/wp-json\/wp\/v2\/comments?post=4473"}],"version-history":[{"count":12,"href":"https:\/\/6thclass.deltapublications.in\/index.php\/wp-json\/wp\/v2\/pages\/4473\/revisions"}],"predecessor-version":[{"id":14762,"href":"https:\/\/6thclass.deltapublications.in\/index.php\/wp-json\/wp\/v2\/pages\/4473\/revisions\/14762"}],"wp:attachment":[{"href":"https:\/\/6thclass.deltapublications.in\/index.php\/wp-json\/wp\/v2\/media?parent=4473"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
