plzmark me as brainlliest
Explanation:
One way multicellular organisms respond to changes in the environment is by behavioral adaptations. An example of this is in a desert ecosystem. Many organisms will seek shelter during the day and hunt during the nighttime when it is cooler.
A dog salivating at the smell of food, a flower opening in sunlight and a worm crawling towards moisture are examples of organisms responding to stimuli from their surroundings. All organisms respond to their surroundings in order to improve their chances of survival and reproduction.
An ice age caused Earth's oceans to cool, which killed many of the unicellular organisms. When the ice age ended and Earth warmed, the continents broke apart. ... The warming of Earth, accompanied by the seas covering the land, created the proper conditions for multicellular organisms to form.
Answer:
MULTICELLULAR ORGANISMS RESPOND TO CHANGE IN ENVIRONMENT BY BEHAVIOURAL ADAPTATION
MANY ORGANISMS WILL SEEK SELTER IN DAY AND HUNTING IN NIGHT BECAUSE THEY WANT TO CONSERVE THEIR ENERGY AND WATER, DURING DAY TIME THERE IS LOSE OF ENERGY AND WATER SO THEY ARE HUNT IN NIGHT
THIS HELPS TO CONSERVE WATER IN THEIR BODIES AND ASSIST WITH THERMOREGULATION
ANYTHING IN THE ENVIRONMENT WHICH CAUSE CHANGE IS CALLED STIMULI
ORGANISMS RESPOND MAANY STIMULI LIKE LIGHT, WATER, HEAT, TEMPERATURE, SUNLIGHT, ODOUR, SMELL, CHEMICAL, FORCE, GRAVITY, PRESSURE.
HOPE THIS HELPS YOU DEAR
