Ecologist study population by mark and recaptur tagged and released.
Ecologists can estimate population size through methods such as mark-recapture, distance sampling, and census surveys. Mark-recapture involves capturing and marking individuals, releasing them, and then recapturing a sample to estimate total population size. Distance sampling involves estimating population size by observing and recording the distances to individuals from a specific vantage point. Census surveys involve conducting a thorough count of all individuals in a specific area.
An ecologist might use observation to study a population of mountain goats. This is because they are not interfering with them.
There are several things that demographers use to predict how a population will grow. Some of them include gender balance, age, income levels and so much more.
The ecologist is using the mark and recapture method to estimate the population number of a certain species. This involves capturing, marking, and releasing a sample of individuals, then recapturing a new sample later to estimate the total population size based on the proportion of marked individuals in the second sample.
The study of changes in a population's size is called demography. It involves analyzing birth rates, death rates, migration patterns, and other factors that can influence population growth or decline. Demographers use mathematical models to predict future population trends.
when there is only small amount
they help predict future population growth, to predict how the worlds human population will grow
they help predict future population growth, to predict how the worlds human population will grow
soem uknown factors that make it hard to predict the future size of human population are:::::: -disease ( ex: who knows when another h1n1 outbreak will occur!) -war ( who knows how the wars and future wars will affect population) -natural disater ( another earthquake, hurricane, tsumami,ect.)
His brother was an ecologist by profession. This is a sentence using the word ecologist.
