Question

1 point a marsh ecosystem, alligators feed on blue crabs Blue crabs feed on saltmeadow grass, shrimp, and detritus. What would most likely happen to e food web if there were a sudden decrease in the number of blue crabs? None of the above The population of shrimp and saltmeadow grass would decrease while the population of alligators would increase. The populations of shrimp and saltmeadow grass would remain the same while the population of alligators would increase. The populations of shrimp and saltmeadow grass would increase while the population of alligators would decrease.

Answer 1

The populations of shrimp and saltmeadow grass would increase while the population of alligators would decrease.

Answer 2

## Step 1This problem is about the dynamics of a food web in an ecosystem. The food web is a graphical representation of the feeding relationships among species in an ecosystem. In this case, the food web consists of alligators, blue crabs, shrimp, and saltmeadow grass.## Step 2The problem states that blue crabs feed on saltmeadow grass, shrimp, and detritus. This means that blue crabs are a primary consumer in this food web, feeding on producers (saltmeadow grass) and other consumers (shrimp and detritus).## Step 3If there is a sudden decrease in the number of blue crabs, it would disrupt the balance of the food web. This is because blue crabs are a significant source of food for other species in the ecosystem.## Step 4With fewer blue crabs, there would be less competition for food among the other species. This could lead to an increase in the populations of shrimp and saltmeadow grass, as there would be less competition for these resources.## Step 5However, the decrease in the number of blue crabs would also mean less food for alligators, which are the predators of blue crabs. This could lead to a decrease in the alligator population.
