Explanation:

1. Mammals have important roles in the food webs of practically every ecosystem. Mammals are important members of food chains and food webs, as grazers and predators. ... Fruit-eating bats (Figure below) also receive food from plants. In return, they help these plants spread their seeds.

2. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism.

Mutualism: both partners benefit. ...

Commensalism: only one species benefits while the other is neither helped nor harmed.

3. Mammals also do work for us. ... Humans also use some mammals for food. For example, cows and goats are commonly raised for their milk and meat. Mammals' more highly developed brains have made them ideal for use by scientists in studying such things as learning, as seen in maze studies of mice and rats.

The Golden Retriever is a land animal, they spend almost the entirety of their lives on land, but they can also swim if needed. The Golden Retriever's origin was in there UK area and a couple places around like Scotland and England.
