What does competitive exclusion theory state?
1. Two closely related species competing for the same resources cannot co-exist indefinitely and competitively inferior one will be eliminated eventually
2. Human beings are the most widespread agents of disturbance
3. In a competition for similar resource, both the participants are benefitted in limited resources
4. In a competition, both the participants are in state of diapouse
1. Rivet-Popper Hypothesis
2. Gause’s Competitive Exclusion Principle
3. Hardy Weinberg Principle
4. Verhulst-Pearl logistic equation

The most observed circumstantial evidences in favour of Gause's principle is
1. Extinction of Abingdon tortoise
2. Extinction of Health hen
3. Extinction of Tasmanian wolf
4. Extinction of Dodo
| 1. | Increased predation from introduced carnivores. |
| 2. | Habitat destruction caused by human settlement. |
| 3. | Overgrazing of vegetation by introduced goats, which outcompeted the tortoise for food resources. |
| 4. | Climate changes that decreased its primary food sources. |
1. feeding at the same time
2. choosing different foraging patterns
3. increasing time spent on attacking each other
4. predating on each other
| 1. | superior species to exclude the inferior species from the habitat. |
| 2. | co-existence of competing species. |
| 3. | reproductive isolation and speciation. |
| 4. | competing species to grow exponentially. |
| 1. | Two closely related bird species competing for nesting sites in a cave |
| 2. | Fishes and flamingos consuming the same zooplankton in shallow South American lakes |
| 3. | Two species of grasses competing for nitrogen in nutrient-poor soil |
