What are examples of symbiosis competition and predation in organisms?

Answer 1

Some symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival cannot live on their own. Others are facultative, meaning that they can, but do not have to live with the other organism.
Symbiotic relationships include those associations in which one organism lives on another
(ectosymbiosis, such as mistletoe), or where one partner lives inside the other
(endosymbiosis, such as lactobacilli and other bacteria in humans.

Competition happens when two parties want the same thing, but there isn’t enough of it to go around. You see it every day at work, sports events, etc. In nature, it would be seen between two packs of wolves or prides of lions.
Organisms compete for the resources they need to survive: air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem has a rich diversity.

Predators feed on other organisms and need them for life and to reproduce.
A red-tailed hawk is a generalist predator; they eat anything from rodents to reptiles to other birds. They are good competitors with other Birds of Prey because they consume a wide variety of prey so their options are many. Specialist predators, however, like the osprey, which eats strictly fish, are limited in their prey selection as well as their geographic range because they have to live in areas where their prey resides.
