1.What is the main factor causing the salinity of the Everglades to change?(1 point)

snake populations

flood control levees

climate change

transportation canals

2.Which animal was responsible for a 99% drop in the opossum populations in the Everglades by 2012?(1 point)

wading bird

fox

python

whooping crane

3.How are Burmese pythons and whooping cranes similar?(1 point)

Both species were relocated to new environments as pets.

Both species’ populations were affected by human actions that caused environmental changes.

Both species’ populations were almost wiped out because of a variety of environmental changes.

Both species became top predators in their new environments.


4.A student is conducting research on the impact of humans on whooping crane populations in the North America. Which statement best supports the student’s claim that animals have been positively impacted by human intervention?(1 point)

Captive-bred whooping cranes have been introduced to natural environments.

In the 1800s, North America was home to over 1,000 whooping cranes.

In the early 1900s, the U.S. and Canada jointly signed a migratory bird treaty.

Although the hunting of whooping cranes was criminalized, their numbers continued to decline.

Explanation:

1. The Burmese python is an invasive species in the Everglades ecosystem. This means its numbers increase dramatically due to lack of natural predators. The python is feeding on small mammals such as rodents that feed of egg of animals such as the turtles. This, therefore, causes a ripple effect on the food web in the ecosystem e.g  dramatically increasing turtle population.

2. Due to the lack of natural predators in the ecosystem, the Burmese python causes an imbalance in the Everglade ecosystem. They reduce the biodiversity of the ecosystem hence diminishing the quality of natural resources.

3. The number of Burmese pythons can be regulated by introducing a predator in the Everglade ecosystem. Examples of animals that can prey on the snake are eagles, pumas, lions, crocodiles, cobras, and humans. This will reduce the numbers of the Burmese python and restore the balance in the ecosystem.

Climate change leads to salinity, the python is responsible, the populations were affected due to human actions that caused environmental changes. In the early 19th, America and Canada signed a migratory bird treaty.

What is the explanation of the above answers. ?

The   Everglades is a wetland preserve of southern Florida and is made up of coastal mangroves. Due to the impacts of the climate the region is under threat from the rising seawater and hence salinity is also one of the factors that are due to climate change.

The python is a species that is responsible for the 99% for drop in the level of the possum population of the everglades.  The native Burmese's python is a cause of animal decline they are similar to the cranes because both of them are wiped by the environmental changes made by man.

As per the research of the student the impact of human whooping cranes in North America is due to the early 19th century both the US and Canada signed the migratory bird treaty.
