How do symbiotic relationships evolve? ! ! i need

~Hello There!~

To get this concept you need to understand natural selection. This is where nature favors those with better adaptations for survival. Certain species help others get things for survival e.g food. As natural selection goes on, these organisms depend more on the symbiosis for survival because natural selection favored those traits over others.

Hope This Helps You!

Good Luck :)

Have A Great Day ^_^

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
