Which marine habitats would have the least access to primary producers?
a.
salt marshes and estuaries
b.
coral reefs and lagoons
c.
mangroves and intertidal zones
d.
deep sea and sea floor

Correct answer choice is :

D) Deep sea and sea floor

Explanation:

The producers in all oceans, including the coral reefs, are essentially algae and phytoplankton, tiny photosynthetic plants that create food from water and sunlight. General forms of algae, like kelp, exist in cooler waters.Marine environments are the home to seaweeds, or marine algae, seagrasses, which are the only aquatic flowering plants, and mangroves, placed on muddy tropic beaches.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
