Question

question new technology is helping scientists locate orangutans on borneo, a southeast asian island. in the last century, the bornean orangutan population has declined from roughly 230,000 to about 104,000 individuals. when it comes to critically endangered species, however, rough estimates are not good enough to help ensure their survival. thats why an unlikely team of ecologists and astrophysicists, who study space, are teaming up. they have used cutting - edge, remote - controlled drone technology to count the animals from the sky. they outfitted a drone with the same type of thermal imaging camera used by astronomers to look at the stars. this device measures the amount of heat that an object gives off. the team found the system was not very reliable during the day. however, it worked well before 9 a.m. and after 7 p.m. that is when the air temperature is cool enough to determine the difference and spot the apes body heat. orangutans werent the only species caught on camera. the drones also picked up on a troop of proboscis monkeys and a group of pygmy elephants. in previous tests, the team also used the drone to track mexican spider monkeys and rabbits in south africa. this is not the only way drones are affecting ecology. drones are being used to collect samples from plumes of water shot out of whale blowholes. they are also being used to estimate numbers of nesting birds, seals and turtles, and to monitor things like land - use change and deforestation jason daley, smithsonian.com, adapted by newsela staff 04/17/2019 which list includes only biotic factors mentioned in the article? scientists, proboscis monkeys, pygmy elephants, spider monkeys, and rabbits endangered species, drone, stars, nesting birds, sky, heat, and thermal imaging land - use, space, camera, heat, air temperature, plumes of water, and stars animals, sky, thermal imaging, land - use, seals, orangutans, heat, and turtles

Explanation:

Biotic factors are living components of an ecosystem. Probosci's monkeys, pygmy elephants, spider monkeys, rabbits, nesting birds, seals, orangutans, and turtles are living organisms.

Answer:

probosci's monkeys, pygmy elephants, spider monkeys, rabbits, nesting birds, seals, orangutans, turtles
