In a marsh ecosystem, alligators feed on blue crabs. blue crabs feed on salt meadow grass, shrimp, and detritus.
what would most likely happen to the food web if there were a sudden decrease in the number of blue crabs?

The populations of salt meadow grass and shrimp would increase.

The population of alligators would decrease.

Explanation:

According to the given information, blue crabs are prey species for alligators. A sudden decrease in the number of blue crabs would reduce the food availability for alligators and food scarcity would reduce their population size.

On the other hand, blue crabs feed on salt meadow grass, shrimp, and detritus. A sudden decrease in the number of blue crabs would increase the population size of salt meadow grass and shrimp. Detritus would accumulate in the system.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
