Explanation:

A niche is the role and position a species has in its environment, including what it eats, how it obtains food, and its interactions with other species. Symbiosis means "living together" and occurs when two species have a close - long - term interaction. Parasitism is when one organism (parasite) benefits at the expense of another (host), like a tick on a dog. Predation is when one organism (predator) hunts and eats another (prey), e.g., a lion eating a zebra. Herbivory is when an organism eats plants, like a cow eating grass. Competition is when two or more organisms compete for the same resources such as food, water, or territory. Mutualism is a symbiotic relationship where both species benefit, like bees and flowers (bees get nectar, flowers get pollinated). Commensalism is a symbiotic relationship where one species benefits and the other is neither helped nor harmed, like barnacles on whales. A generalist is an organism that has a broad niche and can use a wide variety of resources. A specialist is an organism that has a narrow niche and is adapted to use a very specific set of resources.

Answer:

A niche is: The role and position of a species in its environment.
Symbiosis means "living together" and happens when two species have a close, long - term interaction.

Interaction	Species 1	Species 2	Definition and example
Competition	Competing organism 1	Competing organism 2	Organisms compete for resources (two plants competing for sunlight).
Mutualism	Mutualist 1	Mutualist 2	Both species benefit (bees and flowers).
Commensalism	Commensal 1	Neutral species 2	One benefits, the other is unaffected (barnacles on whales).

A generalist is: An organism with a broad niche and wide resource use.
A specialist is: An organism with a narrow niche and specific resource use.

1. Mutualism
2. Commensalism
3. Parasitism
