which is a predator/prey relationship found in a freshwater ecosystem?

a. heron/fish

b. shark/crab

c. tiger/gazelle

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
