Q1. The realized niches observed in nature are often larger than the fundamental niches of the organisms being observed. True Submit Q2. The competitive exclusion principle only applies when the niches of competing species are different (i.e., do not overlap). True Submit ● False Submit False Q3. Four snake species colonize an island at the same time. The species are biologically identical in every way and the island is habitable to them. If nothing changes, which of the following options is most likely to happen over time? All four species will coexist because they will divide up the prey on the island. All four species will go extinct because they have identical niches. D One species will develop a new realized niche and survive while the others go extinct because of competition. One species will persist, but we cannot predict which one; the others will go extinct because of competition.

When species occupy the same niche, they must compete with each other for limited resources. Check each outcome that is likely to occur in the long-term if two species occupy the same niche. (Select all that apply): O Exclusion of one species from the entire niche, but not the other. OExclusion of both species from the entire niche. Persistence of both species throughout the entire niche. O Division of the niche into two smaller niches, each dominated by a single species. Alternating cycles where one of two species is initially excluded but subsequently becomes dominant, excluding the other.
1. What are the three types of ecological relationships? 2. What is "symbiosis"? 3. What are the types of symbiotic relationship? 4. Describe each type of relationship and give examples. 5. What is " Predation" and "Competition"? Why is "predation and competition" necessary among organisms in an ecosystem? Cite examples to support your answers. 6. Describe the two types of competition and give examples.
