Explain how shark populations have changed over time?
Shark populations have declined significantly over time due to overfishing, habitat destruction, and climate change. Many shark species are now threatened or endangered, with some populations decreasing by as much as 90%. Conservation efforts are being made to protect sharks and their habitats to help stabilize their populations.

What is the biggest endangered animal?
The blue whale is the largest endangered animal. Despite their size, blue whales are considered endangered due to threats such as ship strikes, pollution, and climate change impacting their populations. Conservation efforts are underway to protect and preserve this species.
Are wildlife populations static (stay the same) or do they fluctuate (change) as part of an overall balance?
They change over time in response to factors in the environment such as weather and food supplies.
Scientific study of human populations?
The scientific study of human populations is called demography. Demography involves analyzing statistics related to population size, density, distribution, age structure, and other characteristics to understand trends and patterns within populations. It helps to inform decision-making in areas such as public health, economics, and social policy.
How do seasonal variations affect population and ecosystem?
Yes. Seasons can change the size of populations
What natural factors can change a population?
parasites predation weather and clement are four ways natural factors can change a populations size.
Does natural selection require small population size?
No. Natural selection works in all populations. However, new alleles spread more slowly in large populations; the large size has a stabilizing effect. So one should expect large populations to change more slowly than smaller populations.

How does the size of the human population change with time?
Like the populations of many other living organisms,the size of the human population tends to increase with time.
What difficulties have resulted from the change in the size of world populations?
The difficulties is that there is many people in one country that the housing and the food is not enough for all of them. Also jobs.
What is happening to the size of populations?

Which factors affect a populations growth regardless of the populations size?
density - dependent limited factors

How might a change in one populations affect other populations in a community?
It would change because when a population changes, a community changes too.
What is the study of the characteristics of populations called?
The study of the characteristics of populations is called demography. Demography examines various aspects such as population size, density, distribution, age structure, birth and death rates, and migration patterns. This field provides insights into how populations change over time and the implications for social, economic, and environmental issues.
