Habitat vs. Niche HABITAT All organisms have an established habitat. The habitat is the place where a particular species lives and from which it obtains what it needs for survival. EXAMPLE Brook Trout ( PA state game fish. Called brookies ) are native to Eastern North America. Prefer cold, clean, highly oxygenated water (moving water) Stocked in numerous bodies of water in PA.
Habitat vs. Niche NICHE The role an organism plays in their habitat is called its niche. A niche, or it s lifestyle, is when the organism is active, how it eats, or when it EXAMPLE Brook trout have a diverse diet and will eat just about anything that fall into the water. Spawning occurs in the fall. A short-lived species, usually less than five years in the wild.
PA State Record: 22 -inch, 7-pound brook trout. World Record: 14 lbs. 8 oz.

Relationships There are 3 major types of relationships 1. Competition - with others of the same species or other species for resources. Wild Brook trout have to compete with hatchery raised brook trout for resources in the wild. 2. Feeding - all animals are predators to some degree. Herbivores prey on plants. Carnivores prey on other animals. Omnivores prey on both plants and animals. Most ecosystems tend to have a top carnivore or omnivore. Brook trout are preyed on by mink and fish-eating birds. (like osprey)
Relationships 3. Symbiotic are when two organisms live in close association with each other. The relationship can be beneficial, harmful or indifferent. Mutualistic - both organisms benefit. Parasitism one organism benefits (the parasite) and one organism is harmed. (the host) Commensalism one organism benefits and the other organism is neither helped nor harmed.
