2. a sharp decrease in human death rate.
3. (both)
4. (neither)

True/False:

• If you ask a population ecologist, all the individuals in a population belong to the same species. : True
• A single population might exist in multiple territories that do not overlap, with no migration of individuals between territories.,true
• A population's carrying capacity depends on the action of parasites. fasle
• Most populations have a random dispersion pattern. False
• In general, animals are most likely to die at an age near their maximum possible lifespan. fasle

Answer 1

ANSWER -

there was a sharp decrease in the mortality rate in the early tweentieth century, this occured because there were various factors governing for it, one of them was the increased living facility and standard due to the rise of industrialisation, also there was a kind of economic bom , people were earning well and there were improve hygeine conditions along with the improve sanitation facility. all these were simultaneously took place one after another.

therefore, there was a sharp decrease in the mortality rate in the early tweentieth century

TRUE FALSE

1)TRUE - population in terms of ecology is a group of living beings living together in a particular area who can breed together and belong to the same species. and to make it more clear, do we count animals or birds in our census?? no>? right? therefore, population is a group of same species living together.

2) TRUE - different population of same species can live in different areas without being overlapped, humans living in australia and humans living in russia , both will survive and continue to grow even if there is no migration and no overlapping.

3) FALSE - how can parasite govern the maximum carrying capacity of a population? carrying capacity is defined as the maximum growth of a population in an area with maximum outcomes, provided all resource requirements are met.

4) FALSE - as there are various type of dispersion pattern , its not necessary that the dispersion pattern is random, there are other patterns of population like uniform pattern , clumped pattern. example of uniform pattern are plants who secretes toxins to inhibit the growth of nearby plants, example of clumped dispersion are animals who travel in groups like elephant.

5) FALSE -well, a lot of other factors also depends on it, and also if we change the nutrients and the way of living of animals, then they can live for more than their average life span, experiments were conducted for the same where it has been seen that after changing the food habits and type of nutrients the mice and rat survive for a longer period of time than the average.
