The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.

The correct answer is -

Gar population: increase

crabs: decrease

diving duck: decrease.

Explanation:

As it is known that alligators eat gar in any aquatic ecosystem and gar depends on the crabs for their food and nutrition and share the crab population as food with diving ducks in a particular ecosystem. So if the alligator population decrease in the ecosystem then The gar population will increase as there are fewer or no alligators eating them.

And as the population of gar will increase then there would be a decrease in the population in crab population as there will be more gars to eat them and the population of diving duck will reduce due to the increase in the gar population which results in competition for the crabs as food.

Gar population: increase

crabs: decrease

diving duck: decrease

Explanation:

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
