Apopulation of zebras experienced ten births, six deaths to predation, three deaths to disease, three individuals joining the population, and zero individuals leaving. what is happening to the population growth?
a.) it is increasing.
b.) it is decreasing.
c.) it is staying the same.
d.) it reaches carrying capacity.

It would be: 10-6-3+3-0 = 4

A.) It is increasing

a.) it is increasing.

Explanation:

The population density can be define as the number of individuals in a population per unit area in a concerned time. The population density can be influence by factors such as birth rate, death rate, immigration rate and emigration rate. The birth rate can be defined as the number of live births in a population per unit area in a concerned time. The death rate can be define as the number of deaths in a population per unit area in a concerned time. The immigration rate can be define as the number of individuals who arrive in the concerned location in a concerned time. The emigration rate can be define as the number of individuals of the population who depart from the concerned location in a concerned time.

According to the given situation, ten births and three individuals joining the zebra population will increase the individuals in the population, therefore the population will increase by 10+3= 13

Also there were six deaths and zero individuals leaving the area, therefore the population will decrease by 6

The number of increasing individuals are more than the decreasing ones (13>6). Therefore, the population growth will increase.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
