Answer:
Amount of food is independent variable
Explanation:
As food increases the population increase and population is the dependent variable. hope this helps :)
<span>The option which is a limiting factor for a ground squirrel population is a population of hawks. If hawks were to overpopulate the area, that would obviously negatively impact the population of ground squirrels given that hawks are birds of prey which feed of small rodents such as squirrels, among other things. So a large number of hawks would limit the number of squirrels that live on the ground.</span>
The level of organization is plants, coral and water. Water came first.
Answer:
Purpose: to impart better night vision to nocturnal animals by increasing the available light for photoreceptors.
It is called "tapetum lucidum".
Explanation:
The reflective material in the choroid coat of some nocturnal vertebrates is called "tapetum lucidum". Its function is to improve the night vision of nocturnal animals. The tapetum lucidum serves to reflect the dim light available in the night. The reflected light re-stimulates the photoreceptor cells present in the retina. This increases the available light for night vision.
Tapetum lucidum makes the eyes of nocturnal mammals to shine at night.
The coral provides the algae with a protected safe environment (a home) and compounds they need for photosynthesis. The algae in return, produce oxygen and help the coral to remove wastes. Most importantly, zooxanthellae supply the coral with glucose, glycerol, and amino acids, which are the products of photosynthesis.
