This content explores various biological concepts, including how students can get sunburned due to skin exposure during races, emphasizing the skin as a vital organ in the integumentary system. It also highlights the significance of green plants for animals by producing food and releasing oxygen. Additionally, we discuss the internal structures of organ systems and examine bat behavior, focusing on their unique echolocation abilities and how they navigate their environment, even when their eyesight is not utilized for hunting.

Notes: Several students get sunburned during the race. The skin is an organ in the integumentary (skin) system.
Notes: Green plants are important to animals because the plants produce food and give off oxygen. (⏎Food)
Notes: All of the internal structures shown are an organ system (made up of cells, tissues, and organs).
Notes: Bats can detect echoes because low frequency sounds have long wavelengths that are too broad to pinpoint motion in objects that small.
Notes: A bat species can hunt perfectly well without its eyes; sight may be a favorable trait, but not for hunting.
