Q2. Based on your knowledge of community ecology, what other factors may affect nuthatch abundance?

1. predation 2. competition 3. mutation 4. all of the above 5. predation and competition only

Q3. The statement- "to examine overall diffrences between the marine reserve and the unprotected area, proportional abundances and biomasses for each species (number of individuals of one species divided by the total number of individuals caught) were calculated for each sampling trawl" - would be found in which section of a scientific paper?

1. Discussion 2. Introduction 3. Methods 4. Results 5. Title

Q4. A species of birds is likely to be more aggressive towards another, distantly related species that fills a similar ecological niche, than antoehr closely related species that fills a different ecoloigcal niches.

True or False

Answer 1

2. Community ecology is association of two or more different species of organisms that occupy the same geographical area in a particular time. The factors that affect the abundance of a species in community ecology are predation, competition, and mutation.

Hence, the correct option is 4.

4. The aggressive behavior of birds is not restrained to birds of other species. For example, the males of same species fight with one another for reproductive access to females. Similarly, the domestic chickens (both male and female) show aggressive behavior to achieve and maintain status in dominance hierarchies. The aggressive behavior is of two types predatory or anti-predatory. The birds defend themselves from other birds.

Allopatric speciation is the common method in which the two separate species of organisms are formed due geographical isolation. Hence, related species occupy different ecological niche

Hence, the statement is True.
