Compare the water cycle with the carbon cycle. What do both have in common?

The water cycle uses plants for uptake of water and transpiration from the surface, so that water can be sent to the atmosphere. Carbon cycle uses plants for uptake of CO2, by which it is removed from the atmosphere (and sent back to atmosphere when the plant is dead).

Hope this helps

Explanation:

The water cycle uses plants for uptake of water and transpiration from the surface, so that water can be sent to the atmosphere. Carbon cycle uses plants for uptake of CO2, by which it is removed from the atmosphere (and sent back to atmosphere when the plant is dead).

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
