What are 3 environmental variable that affect the size of population?
Water is one of the main environmental variables that can affect the size of a population. For a population to thrive water must be both available and safe for drinking.
What are the causes and effects of environmental destruction?
Environmental destruction is caused by climate changes, population expansion, and toxic gases being emitted into the atmosphere. The effects of environmental degradation are that resources such as wildlife, water, and soil can be permanently changed.

What are defactors that affect the process of natural selection?
Some factors that can affect the process of natural selection include mutation rate, genetic diversity within a population, environmental changes, competition for resources, and presence of predators. These factors can influence which traits are favored or selected for in a population over time.
How might one change in one population affect other population in a community?
It would change because when a population changes, a community changes too.
What Factors affect population?
Factors that affect population size include birth rates, death rates, immigration, and emigration. Additionally, access to healthcare, socioeconomic factors, education, and environmental conditions can influence population growth or decline. Government policies and urbanization also play a role in shaping population changes.
How do environmental changes affect the Great Barrier Reef?
Environmental changes, like global warming, can affect the Great Barrier Reef quite substantially. When the water temperature rises, it forces the coral to expel what they use as energy, and bleaches the coral.
How can population changes affect demand for certain goods?
immediate demand for a good will go up if it's price is expected to rise. this is how population changes affect demand for certain goods.
Describe three factors that affect changes in the human population of Ireland?
There are 2 major categories that affect the population of a country. One being environmental, the other non-environmental. Environmental Categories... 1. Disease 2. Natural Disasters 3. An unbalance of predator prey relationship. Example, a decline in the fox population will increase the amount of hairs (rabbits). Non-environmental Categories... 1. Death 2. Birth 3. Emigration (When one leaves their country) 4. Immigration (When one enter another's country). Hope this was helpful.
Spontaneous changes in genetic material are called?
Spontaneous changes in genetic material are called mutations. These changes can occur naturally during DNA replication or as a result of environmental factors such as radiation or chemicals. Mutations can affect an organism's traits and may contribute to genetic diversity in a population.
What is a factor that might cause the carrying capacity of a population to change?
Environmental changes such as availability of resources, changes in predation pressure, or disease outbreaks can affect the carrying capacity of a population by either increasing or decreasing the amount of resources available for the population to survive and reproduce.
