Animals exhibit basically the same types of interactions as humans.The male is usually the stronger of the species and is usually territorial. However, in the animal world the female is the one who chooses who to mate.
On the primitive level of both animals and humans, when they first see another animal they have to decide whether the other is a threat or not. Different animals have different ways of doing this but a lot is from instinct (learning how to survive).
Once they determine there is no threat they may be curious and friendly. Not very many animals are like this though. Most are thinking of protecting their territory (space) and usually don't want anyone else in it. Humans like to protect their territory also!
So with the above, there are different forms of agression. Physical contact may or may not occur. Example: sometimes cats will just growl at each other but not fight. The human animals does everything from facial gestires to physical gestures to all-out mass war. That's what happens when animals form groups.
Usually most types of animals avoid each other. Some may tolerate being in the same area but don't make physical contact. Within some species you will find that certain animals don't even want to be around one of their own kind, unless it's to mate.
A person who studies how animals interact with their environment is called an Ecologist.

the study of biology includes the investigation of interactions among species
Ducks are among the most versatile animals for various reasons. There are different types of ducks which provide humans with eggs, meat and feathers.
Ecology, the study of interactions among organisms and their ecosystem.
Symbiosis. Some different animals species even co-evolve based on their interactions. Could be that there is a misfiring of a behaviour as well in some cases.
Some examples of animals that live in lakes and ponds are fish, frogs, freshwater clams among many other animals.
